- Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
- Further stabilization for the Intel 960.
- * Makefile.dist: Parameterize the location of the "include"
- and "bfd" directories, as well as "getopt". Add symfile.c.
- Link in both dbxread and coffread. Fix up "make depend" to
- rewack the locations of include, bfd, and getopt in its output.
- * README: Document moving include files, improve some of
- the other doc.
- * coffread.c: Move common code out to symfile.c. Change
- symbol_file_command style interface to use new *_symfile_init
- and *_symfile_read interface under BFD. Use BFD internal
- info to locate line table, symbols, etc.
- * core.c (core_fetch_registers): Rename to get_core_registers
- to avoid confusion with fetch_core_registers.
- (register_addr): Move to coredep.c, which is already machine
- dependent. This leaves core.c pretty clean of dependencies.
- * coredep.c (register_addr): Accept this routine from core.c.
- * dbxread.c: Move common code (with coffread.c, etc) into new
- symfile.c. Each psymtab now contains a pointer to the
- format-dependent function that knows how to read it in. Make
- some things static.
- (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
- (process_one_symbol): Add code to complain about a "compiler bug
- we muzzle here", if we actually see it.
- * eval.c (evaluate_subexp): Insert missing "break" statements
- in code that determines whether a variable is an lvalue in
- memory, register, or whatever. I detected this via a compiler
- bug in which it *almost* mashed out the whole switch statement.
- * gdb-int.texinfo: Add minor sections on configuring gdb for
- release, and about the README file.
- * infcmd.c (registers_info): Fix formatting somewhat. Still
- not as pretty as before, but it handles byte swapping.
- * remote-nindy.c: If data cache routines are interrupted while
- waiting for the remote end, be sure that any uninitialized cache
- blocks are on the free list, not on the valid list!
- * symfile.h: Flesh out this header file with all the various
- routines and variables that have been merged in from dbxread.c
- coffread.c, and symtab.c to symfile.c.
- * symfile.c: New file, containing code common to dbxread.c,
- coffread.c, and some code from symtab.c. All generic code for
- reading symbol files should be in here now.
- (unrecord_misc_function): Remove unused function.
- * symtab.h: Remove file-reading things to symfile.h.
- * symtab.c: Remove file-reading things to symfile.c.
- * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
- to decode i960 fault types.
- * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
- target.c: Change type of the "resume" function from int to void,
- since its result was never used.
- Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
- * main.c: Replace "stupid" with "caution"; you now "set caution
- on or off".
- * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
- * infcmd.c (do_registers_info): Call val_print to deal with the
- byte order of the registers being printed. FIXME, this makes
- the formatting of the output uglier.
- * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
- defined, call it for signals the debugger doesn't itself use.
- The i960 uses this for more detailed fault information.
- * remote.c (remote_open): If arg is null, print help rather than
- dumping core.
- * sparc-xdep.c (register_valid): Avoid declaring size, since
- various modules will think of various sizes depending on the
- architecture of their tm-file. FIXME, we need protection against
- actually entering one of those modules, which would clobber
- storage if not for the target architecture compiled into gdb.
- * stack.c (up_command, down_command): Always print the frame
- you arrive at.
- (up_silently_command, down_silently_command): New commands
- for use in scripts.
- * i960-pinsn.c (reg), i960-tdep.c: Lint.
- * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
- more parameters than it used to.
- * findvar.c (registers): Increase slop to 256 bytes, which should
- protect us against even most RISC machines with large register
- sets.
- (locate_var_value): Move declaration inside related ifdef.
- * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
- throughout, to avoid throwing away buffered input from the board.
- (nindy_wait): Supply_register takes addr_of_value, not value.
- (i960_print_fault): Renamed from i80960_fault.
- (nindy_fetch_registers): Avoid have_regs stuff, just get them.
- (nindy_store_registers): Avoid regs_changed stuff, just stuff
- them.
- (nindy_create_inferior): Don't bother to write PC_REGNUM since
- we can set the PC in the call to proceed(). Unpush nindy_ops
- before pushing it on top, to avoid message to user. Eliminate
- commentary from Unix machines that just misleads here.
- (reset_command): Fix error message to suggest target command.
-
- Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
- Release 3.92.5 as frozen.
- Stabilize the merged release...with help from lint, Saber C,
- gcc -W, etc.
- Everywhere: Add include files needed to declare return types
- of functions called.
- * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
- * breakpoint.h: Add undeclared breakpoint functions, and some
- functions for display handling since I couldn't think of a better
- .h to put them in.
- * breakpoint.c (insert_breakpoints): Make code for disabling
- shared library bkpts more likely to work. It's used when we
- rerun a program and stop before the shared library has been
- mapped in.
- (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
- cast from pointer, so it squeezes through catch_errors.
- (bpstat_stop_status): Fix logic broken some time ago. We now
- always create a bpstat if the stop address matches a breakpoint,
- even if we don't stop there -- just like the old code used to do
- before I got my fingers into it (sigh).
- (breakpoint_1): Print "ignore count" after "stop only if"
- condition, since that's how it actually works.
- (mention): Handle watchpoints as well as breakpoints.
- (watch_command): use set_raw_breakpoint and mention to do most
- of the work (and initialize all the fields!). Only pass one
- arg to parse_c_expression, since that's all it takes.
- * command.c (not_just_help_class_command): Rename arg to args
- since we ignore "unused argument" warnings on vars named "args".
- inflow.c (child_terminal_info): ditto.
- infptrace.c (kill_inferior): ditto
- main.c (catch_errors, version_info, quit_command, pwd_command,
- source_command, dump_me_command, editing_info,
- set_history_size_command, set_history, show_history,
- set_verbose): ditto
- stack.c (locals_info): ditto
- target.c (target_files_info): ditto
- valprint.c (set_input_radix, set_output_radix): ditto
- * core.c: Remove old variables for handling core and exec file
- sections (data_start, data_end, stack_start, stack_end,
- reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
- text_end, exec_data_start, exec_data_end, text_offset,
- exec_data_offset, data_offset, stack_offset). They're
- superseded the more general build_section_table and
- xfer_memory.
- (get_exec_file): Mention the `file' command.
- (read_memory_check): Rename to memory_error, and only call it
- in the case of an actual error.
- (read_memory, write_memory): call memory_error.
- (core_fetch_registers): Register section name is ".reg".
- coredep.c: Remove a bunch of crud now that all this file does
- is pull the registers out of a core file.
- (fetch_core_registers): Rewrite to actually work, I hope.
- dbxread.c: Use a.out.gnu.h, not system a.out, now.
- Replace index() with strchr(). Remove all the pre-BFD macro
- definitions for accessing the symbol file.
- (struct dbx_symfile_info): Encapsulate the information that
- dbx_symfile_init needs to pass to dbx_symfile_read in this
- struct.
- (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
- dbx_symfile_discard): Rearrange symbol file reading to divide
- the format-specific part from the format-independent part,
- leaving the format-independent part such as file name expansion
- and opening in symtab.c. This replaces
- partial_symbol_file_open and partial_symbol_file_read.
- Symbol_file_read, add_file, add_file_target_command,
- add_file_addr_command move to symtab.c. Pass an explicit
- "mainline" flag for when reading the main symbol table, rather
- than relying on the offset address to be zero or nonzero.
- (dbx_symfile_read): Don't allow void *'s to be printed as
- typedefs.
- (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
- (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
- macro" debug version really work.
- (read_dbx_symtab): Remove unref'd parameter inclink.
- Avoid swapping N_SLINE symbols, for speed.
- Merge N_TEXT!N_EXT case with the other external symbol
- definitions' case. Add comments.
- (start_psymtab): Allocate the symfile name in the psymtab on
- the psymbol_obstack, rather than using the caller's storage.
- (end_psymtab): Only allocate a dependencies list if there are
- more than zero.
- (psymtab_to_symtab_2): Use BFD when reopening file to read
- its symbols for real.
- (read_struct_type): Add FIXME comments where it needs work
- for C++ bogosity.
- (read_huge_number): Add FIXME about overflows.
- (read_range_type): Add FIXME about comparing a long to 1<<32.
- * coffread.c: Minor changes to move things closer to the new
- regime with symtab.c and dbxread.c Major work is still needed
- here.
- * exec.c (exec_file_command): Remove old variables (see core.c
- above).
- (xfer_memory): If memory transfer is right at the end of a
- section, don't lose.
- * findvar.c (get_saved_register): If value is in a real
- register, LVAL is lval_register, not lval_memory.
- frame.h: Declare print_sel_frame and record_selected_frame.
- gdb-int.texinfo: New file, for GDB internals documentation.
- Very simple, unformatted doc of cleanups is there for now.
- gdbcore.h: Remove obsolete variables that described a.out
- section addresses and offsets. (See core.c above.)
- Declare fetch_core_registers and registers_fetched.
- getopt.c: Declare char *alloca(); even on SPARC.
- infcmd.c (run_command): Call target_kill rather than
- kill_inferior.
- (step_command, next_command, stepi_command, nexti_command):
- Declare from_tty parameter even though we don't use it.
- (run_stack_dummy): argument BUFFER is a char array, not
- a pointer to REGISTER_TYPE.
- (finish_command): using_struct_return needed a value *,
- not a struct symbol *.
- * infptrace.c (child_xfer_memory): To avoid dependency on
- where sections are in memory, try PT_WRITE_D and if that fails,
- try PT_WRITE_I. Most Unixes don't care which you use.
- * infrun.c (step_resume_break_shadow): Change to array to
- match other breakpoint shadow storage.
- (clear_proceed_status): Pass address of bpstat to
- bpstat_clear, not the bpstat itself.
- (child_create_inferior): FIXME comment about if the child
- exits.
- (start_inferior): Remove old function.
- (child_open): Use target_kill rather than kill_inferior.
- (wait_for_inferior): Ditto.
- (insert_step_breakpoint, remote_step_breakpoint): Use
- new step_resume_break_shadow.
- * inftarg.c (child_wait): If all child processes die,
- pretend that the one being waited for exited with signal 42.
- * main.c (command_line_input): When scanning for comments,
- don't coredump on unclosed quotes.
- (quit_command): Use target_kill rther than kill_inferior.
- (_initialize_main): Rename class_user from "user" to
- "user-defined".
- * printcmd.c (print_command_1): Initialize "fmt" if no format
- is specified by the user.
- (print_frame_args): Only add to args_printed if we are
- actually fetching args from the stack (avoiding undefined
- arg_size).
- (_initialize_printcmd): Remove bogus \{ from string.
- * remote-eb.c (eb_open): Avoid coredump on no argument.
- * remote-nindy.c: Bring out of Intel environment into new
- target environment. Remove all conditional compilation on
- I80960. Massive hacking throughout.
- (nindy_xfer_inferior_memory): New routine stolen from
- infptrace.c.
- (nindy_create_inferior): New routine pieced together, probably
- not quite working yet.
- (nindy_ops): New target_ops struct for nindy.
- * remote-vx.c: Use write_memory rather than target_write_memory
- to get error checking.
- (vx_add_file_command, vx_open): Use symbol_file_add rather than
- add_file.
- (vx_create_inferior): Use target_terminal_ours...
- * signame.c (_initialize_signame): Always initialize, since
- we need the table for things other than psignal.
-
- * solib.c (solib_add): Use symbol_file_add, not add_file.
- (solib_address): Return boolean result rather than struct
- pointer which nobody else knows the type of.
- * sparc-tdep.c, valops.c: Use write_memory rather than
- target_write_memory, to get error checking.
- * stack.c (locals_info, catch_info, args_info,
- get_selected_block, frame_command, up_command): Use
- target_has_stack, rather than have_inferior_p or
- have_core_file_p.
- * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
- * symfile.h: New file, defining the interface between the
- generic and object-file-specific symbol reading code.
- * symtab.c: Move generic symbol-reading interface to symtab.c,
- from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
- table to map BFD targets to symbol-reading modules in GDB.
- Change index to strchr.
- (lookup_struct_elt_type): Use error() rather than hand-made
- simulations thereof.
- (lookup_partial_symbol): Speedup slightly when length == 0.
- (symbol_file_add): New function.
- (symbol_file_command): Call it.
- (symfile_open, symfile_init): New function.
- (add_file_target_command, add_file_addr_command): moved from
- dbxread.c.
- * target.c (target_command): use target_kill.

- * valops.c (value_assign): FIXME comment that long long
- bitfields will break here.
- * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
- Update `make saber_gdb' to work better.
- * TODO: A woman's work is never done.
- * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
- main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
- remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
- sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h

- valops.c, valprint.c, exec.c: Lint.
- Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
- Continuing Intel 960 port merge of GDB.
- * Makefile.dist: Merge i960 "nindy-share" files. Rename
- malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
- Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
- Wack over "make depend" so it handles files in subdirectories
- vx-share, nindy-share, bfd, and in the current directory.
- * blockframe.c (get_prev_frame_info): Remove fatal error
- if stack not defined.
- * core.c (core_open, core_detach): New functions that handle
- the old "core-file" command as "target core" and "detach" instead.
- (core_file_command): Call them.
- (core_xfer_memory): Use common routine xfer_memory.
- * dbxread.c: Include a.out.gnu.h, not system a.out.h.
- dbxread now uses bfd for everything but symbol reading itself.
- BFD internals are used to drag out the relevant file offsets.
- (partial_symbol_file_open): Change args all around for BFD.
- * symtab.c: Rename "value" to "val" everywhere, so we can
- #include "value.h".
- (symbol_file_command): New command, moved from dbxread.c
- and coffread.c. It uses BFD to read the file, then vectors
- based on its type, to dbx or coff symbol readers.
- * symtab.h: Extern a few vars for symbol_file_command.
- * target.h: Breakpoint takes a char * save area, not a char **.
- * valprint.c (val_print): When unpacking bitfields, offset
- the address in gdb of the value, if it is declared with a shorter
- type. Remove the last "runtime kludge test" of host byte order.
- * utils.c: Remove old my_bfd_read routine.
- * stack.c (frame_info): Use target_has_stack. Print program counter
- register's actual name rather than "pc", since it's called the
- "ip" (instruction pointer) on the i960 (sigh).
- * target.c (target_command): Add command for selecting a target
- type and calling its open routine. This is used for initiating
- communication with a particular target, in a generic way.
- * tm-i960.h: Update for modern gdb. Remove semicolons from
- various macros. Handle reading struct return convention, and
- error-out attempts to return structs with the "return" command.
- Be sure gdb doesn't think we know how to call functions in the
- inferior.
- * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
- to i960_xxx in lower case.
- (arg_address): Circumvent errors due to LOC_ARG_BLOCK
- not being defined yet.
- * remote.c (remote_open): Call start_remote to initialize
- wait_for_inferior during open.
- (remote_xfer_inferior_memory): Return length written rather
- than errno value.
- * remote-vx.c (target_command -> vx_open): Use new generic
- target command.
- * remote-eb.c, inftarg.c, exec.c: ditto.
- * infrun.c: Fix comments.
- (attach_program -> child_open): Use new generic target command.
- (wait_for_inferior): Clear saved register values before target_wait,
- so target_wait can set some of them if convenient.
- * infptrace.c (fetch_inferior_registers, store_inferior_registers):
- Return success indicator, not void.
- (child_xfer_memory): Avoid fetching initial word if we'll
- overwrite it anyway.
- * infcmd.c (attach_command): Use new generic target open routine.
- (_initialize_infcmd): Update doc on attach and detach commands.
- (do_registers_info): Merge in a byte-order problem as a FIXME
- comment.
- * findvar.c (find_saved_register): Avoid problem in current frame.
- (read_relative_register): Ditto.
- (write_register): Convert byte order on the way out.
- * exec.c (file_command): Add.
- (add_to_section_table, exec_command): Use new bfd_map_over_sections.
- (xfer_memory): Common function between core_xfer_memory and
- exec_xfer_memory.
- (exec_xfer_memory): Use it.
- * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
- * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
- valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
- infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
- Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
- Merge Intel 960 port of gdb, continuing...
- * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
- symbol_file_command): Pass from_tty arg to hush 'em up.
- * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
- Add magic numbers for 960 COFF format.
- Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
- Merge Intel 960 port of gdb, from Intel "1.2" release.
- CHANGE_LOG entries from their port, which was based on
- gdb+-2.8.0:
- Thu Sep 6 11:02:22 PDT 1990
- Remove temp file if download is interrupted.
- Wed Aug 1 09:08:33 PDT 1990
- Now uses binary protocol to talk to NINDY.
- Old hex protocol (NINDY 2.13 and older) supported with -O switch.
- Times out after 5 seconds when trying to talk to NINDY.
- Tue May 29 12:54:49 PDT 1990
- Added variable baud rate (-b switch).
- Source code reorganization.
- Thu Apr 26 11:09:55 PDT 1990
- More cleanup of batch mode; specifically, execute "-s", "-e", and
- "-se" switches as soon as they are encountered on the invocation line.
- Fri Apr 20 13:47:15 PDT 1990
- Add -brk switch.
- Thu Apr 19 09:54:28 PDT 1990
- Add 'reset' command.
- Wed Apr 18 09:48:07 PDT 1990
- After opening remote tty, wait for 1 second to go by without input
- from it before trying to talk to NINDY (fixes problems with the
- Heurikon HK80/V960E).
- Mon Apr 4 16:33:05 PDT 1990
- Some output was not being suppressed in 'batch' mode.
- Thu Mar 22 15:31:11 PST 1990
- Ask user if old symbol table should be deleted when new file is
- downloaded.
- Allow user to run a program downloaded before gdb960 was brought up.
- Correct "exec-file" help message for i80960 context.
- Correct bug in calculating user space address: could occasionally
- corrupt user program.
- Make sure to zero low-order bits in rip's because of bug in 960CA
- A-step part: could cause operation faults when "next"ing across
- a function call.
- Correct bug that made it impossible to get source line numbers for
- code loaded at addresses higher than 0x7fffffff.
- Wed Jan 10 12:43:22 PST 1990
- Open remote tty for exclusive use.
- Fri Jan 5 12:14:42 PST 1990
- Correct disassembly (CA manual was right after all):
- opcode for sysctl is 0x659
- Mon Oct 23 12:03:04 PDT 1989
- Use G960BASE and G960BIN environment variables to find 'sx' utility.
- Mon Oct 16 14:15:09 PDT 1989
- "sfr0"-"sfr31" should have been named "sf0"-"sf31"
- Mon Oct 2 15:56:31 PDT 1989
- Added 960CA disassembly support.
- To simplify maintenance:
- - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
- directly instead.
- - eliminated opcode.h: incorporates tables into i960-pinsn.c
- - moved 960-specific routines from i960-pinsn.c to i960-md.c
- - made disassembly interface identical to that in gdmp960.
- Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
- * target.h: Allow targets to stack. Add target_has_memory,
- _registers, etc. Restructure memory access and "info files"

- * inftarg.c (child_files_info): New "info files" regime.
- * remote-eb.c: New memory regime, new info files.
- * remote-vx.c: New memory regime, new info files. Now use
- separate targets for VxWorks attachment to machine, and
- actually running a process under VxWorks, since one has
- stack & execution & regs and the other doesn't.
- * remote.c: New memory regime, new info files.
- * sparc-xdep.c (fetch_core-registers): New memory regime.
- * target.c: New routines and support for stacked targets,
- new memory regime, new info files regime.
-
- Generalize section handling for an arbitrary number of sections,
- including use of the new BFD (binary file) library.
- * gdbcore.h: Add struct section_table.
- * exec.c (build_section_table): Iterate all sections and
- record what gdb needs to know about them.

- targ-vx.c. A few other cleanups.
- * TODO, Projects: Lots more stuff to do...
- Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
- Massive changes to wall off the remote-debugging interface
- behind a function vector. The port to handle VxWorks targets
- is also part of this.
- All files: Replace references to renamed functions,
- remove references to remote_debugging, remove references to
- have_include_file, have_core_file in favor of target_has_stack,
- target_has_memory, etc.
- * Modularize the breakpoint interface.
- breakpoint.h (BREAKPOINT_MAX): New define sets max length of
- a breakpoint instruction.
- breakpoint.c: struct breakpoint's shadow_contents now sized as
- BREAKPOINT_MAX.
- (insert_breakpoints): Vector to target to install breakpoints.
- (remove_breakpoints): Vector to target here too.
- Remove REMOTE_SA_SPARC kludges and other remote_debugging.
- sparc-tdep.c (single_step): Use new breakpoint interface for
- the single-step breakpoints.
- mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
- New file, contains routines to insert and remove breakpoints by
- reading out the old contents and later replacing them. This is
- how ptrace breakpoints work, and many remote systems as well.
- * tm-vxworks68.h: New config file, overrides a few things for
- Wind River's preferences.
- * target.h: New file, for transfer vector used to talk to the
- inferior (child, attached, core, exec, remote, etc). All accesses
- to the thing being debugged should come through these vectors.
- target.c: New file, routines to handle transfer vector.
- (various files): Add transfer vectors XXX_ops for the various
- targets and pseudo-targets (core files, etc) we support.
- * breakpoint.c (bpstat_stop_status): Further explorations of
- watchpoints and why things don't work all the time.
- (bpstat_alloc): New fn to allocate a bpstat and chain it.
- * config.gdb: Only add "source ${srcdir}/.gdbinit" to
- the local gdbinit if it doesn't already have it.
- * core.c (core_ops): add and install.
- Allow core debugging without exec file.
- * dbxread.c (free_and_init_header_files): Merge two fns.
- (end_symtab): Free named symbol table when a new version comes in.
- (read_dbx_symtab): Relocate all kinds of symbols with base
- address. First step toward handling different text, data, bss
- reloc.
- (add_file_addr_command): Renamed add_file_command.
- (add_file_command): Vector to remote handler.
- Add "load" as an alias for "add-file" command.
- * defs.h: Allow "volatile" to be used in non-ANSI; use it for
- non-returning functions.
- * exec.c: Add exec_ops, and push it as a target when an exec
- file is specified.
- * infcmd.c (run_command): Pass executable file name and arg list
- separately when starting an inferior. Permit "run" when no exec
- file is specified, for VxWorks.
- (detach_command): Move to child_detach in inftarg.c.
- * inftarg.c: New file. Unix-child-specific routines, and the
- child_ops structure.
- * inferior.h (registers): Export "registers" as the way for
- target dependent register handlers to find gdb's local copy of
- the registers. Rename "stop_after_attach" to "stop_soon_quietly"
- since it is now used by places that want wait_for_inferior to
- handle the grunge but want to see every trap from the inferior.
- * inflow.c (create_inferior): Pull out, and merge into infrun.c.
- Eliminate remote_debugging hooks in terminal handling.
- * infrun.c: Replace start_inferior with child_create_inferior.
- Move all the hair of Unix shells and ptrace idiosyncracies into
- child_create_inferior, so remote handlers don't have to deal.
- Remove running_in_shell. Rename stop_after_attach to
- stop_soon_quietly, and use it in a few other places where we want
- to just call wait_for_inferior and get control back on the first
- trap. trap_expected now never takes a value > 1.
- (init_wait_for_inferior): Initialize static vars when a new
- process is created.
- main.c (gdbinit): Add new hook for .gdbinit file name, let
- it be overridden by config files as GDBINIT_FILENAME.
- (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
- Both of these are used for VxWorks gdb.
- mcheck.c: rename include file "gmalloc.c" to avoid problems
- with system include file "malloc.c".
- param-no-tm.h: New include file, same as param.h but does not
- include the default "tm.h" file. This is used in files where
- the target is known, e.g. remote-eb.c or sparc-xdep.c.
- param.h: Now just a shell that includes tm.h and param-no-tm.h.
- remote-vx.c: New file, VxWorks remote debugging support. Uses
- RPC routines that are shared with the target system, in directory
- ${srcdir}/vx-share.
- remote.c: Vectorize remote interface.
- source.c: Globalize source_path, and make an alias "l" for "list"
- since we now have the "load" command.
- sparc-xdep.c: Use new param-no-tm.h.
- symmisc.c (free_named_symtab): Add new function from Wind River.
- However, ifdef it out for now while we think about what it should
- really be doing.
- tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
- PREPARE_TO_STORE to
- the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
- non-Unix-children handle this with their own code in the target
- transfer vector.
- Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
- source and target lists. Add vx-share to default list of include
- directories. Add new files to src and target lists: mem-break,
- target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
- ${srcdir} versions of munch and createtags are used.
- * valops.c (find_function_addr): Split out of call_function.
- (call_function_by_hand): Rename call_function; this function
- calls functions in the target by laboriously patching the target
- word-by-word with the right stack, args, regs, etc.
- Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)

- * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
- * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.

- * defs.h (xmalloc, xrealloc): ditto
- * utils.c (quit): Grab the terminal from the child if necessary.

- to "info terminal".
- * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
- (is_delayed_branch): Speed up.
- * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
- Still missing some float ops, and needs testing.
- * Support for input and output radixes other than base 10
- * defs.h (input_radix, output_radix): Declare.

- numbers in varying column widths.
- * valprint.c (val_print): Use output_format to print scalar ints.

- Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
- * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
- bfd stuff is still screwed up, but with some manual work, it
- compiles.
- * breakpoint.c (bpstat_do_actions): Start over if a command
- proceeds the inferior, since the inferior will have stopped and
- will need to have its new stop-actions taken care of.
- * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
- compiler fits, simplify it.
- * gdb.texinfo (directory command): Doc new dir command.
- source.c (directory_command): "dir" now puts things on the front
- of the path, moves dups up front, and handles multiple names
- on the command line, inserting each one in order. It also
- blows away cached line and full_filename info.
- * stack.c (backtrace_command): Skip "more stack frames follow"
- unless interactive.
- * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
- xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
- xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.

- which runs expressions and doesn't print the result if void.
- (print_command_1): implement it.
- * command.c: Remove #if 0'd code. Initialize all the fields
- in add_cmd (). Rename do_nothing_command to
- not_just_help_class_command, and make it externally visible.

- calling convention of value_struct_elt () that got dropped in
- merge.

- sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
- * tm-sparc.h (POP_FRAME): replace some constants with defines.
- * sparc-xdep.c (store_inferior_registers): defer stores to regs
- until a good time (e.g. when we are about to run the child),
- saving ptrace calls.
- * infrun.c (proceed): handle DO_DEFERRED_STORES.
- * tm-sparc.h: define DO_DEFERRED_STORES.
- * sparc-xdep.c (store_inferior_registers): when storing float
- registers, don't store stack regs too. When storing the SP,
- however, DO store the stack regs too. This fixes a bug in which
- the dummy frame is not recognized when a call_function finishes,
- because its frame pointer (in the stack regs) was never
- initialized.
- (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
- even though we don't know how to read them from an inferior.
- valops.c (call_function): Comment about storing SP.
- * infrun.c (save_inferior_status): Save away the original bpstat
- chain so it can be restored later. Install the copied version for
- use by whoever saved the status. It will be blow away by
- restore_inferior_status, and the original chain restored. This is
- important for people who have pointers into the original.
- * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
- findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,

- Add stuff.c and kdb-start.c to the OTHERS list for tar files.
- Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
- * Merge Mike Tiemann's multiple inheritance changes from Sun.
- Store the baseclasses in a type struct starting from array element
- 0 rather than from the unusual array element 1.
- dbxread.c: the above.
- (virtual_context): Add
- Read new debug information about which virtual function table
- a virtual function is from, and store it in fn_field.fcontext.
-
- symtab.h: Add fcontextt. Fix baseclass indices. Typo in
- TYPE_FN_FIELD_STATIC_P.
- symtab.c: the above.
- valops.c: the above. Handle pointer casts of object *'s.
- (search_struct_method): Add.
- (value_struct_elt): First arg is now a pointer to a value, and is
- modified on return.
- valprint.c: the above.
- values.c (value_virtual_fn_field): Add type arg. Handle
- offsetting to the proper object when calling virtual fns.
- The above.
- (baseclass_addr): Add valuep arg.

- we allocate one.
- symtab.c (B_CLRALL): define.
- * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
- using == rather than =. Huh... This fixes the dreaded problem
- wherein builtin_type_int becomes TYPE_CODE_FLT.
- * core.c (info_files): Show the inferior pid.
- * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
- already knows how to look in the source directory.
- * Remove psymtab hair from many places. Remove duplicated code
- for searching symbol tables. Hide psymtabs from most places.
- Make it fast to get from a psymtab to its symtab.
- blockframe.c (blockvector_for_pc): Remove psymtab hair.
- coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.

- dbxread.c: export psymtab_to_symtab, make it work if called N times.
- (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
- new symtab completely. New psymtabs get symtab pointer
- initialized to zero. Remove MI warning printf.
- symtab.h: Comments. Add psymtab to symtab pointer.
- (PSYMTAB_TO_SYMTAB): New macro.
- symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.

- compilation fields.
- stack.c (backtrace_command): Avoid pre-pass to read symbols, if
- verbose is not set.
- (print_frame_info): Avoid special-casing symbols that have not yet
- been read in.
- * source.c (open_source_file): Quick path if we have already
- located the source file by its full name.
- * symtab.c (lookup_symbol): Use find_pc_symtab rather than
- find_pc_psymtab. When a name is found in the misc function
- vector, search the symbol table for its mangled name, not the
- name that the user typed.
- * bfd.h: Fix missing comment terminators, make #endifs match.
- * valarith.c (value_less): Handle unsigned int comparisons.
- Add FIXME about pointer compares, which assume host and target
- pointers are the same.
- * command.c (do_nothing_command): lint
- dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
- fix comments on debug symbol format for visibility. Actually set
- visibility of symbols.

- tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
- obstack.h (_obstack_blank): Rearrange pointer math to avoid
- pointing past end of allocated memory; saber complains.
- obstack.h: Declare the external functions that we use.
- valarith.h: use <string.h>
- solib.c (solib_add): lint.
- Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
- * main.c (initialize_main): Default info_verbose to off, now that

- * Initial BFD (binary file diddling library) merger:
- coffread.c: Change AOUTHDR to struct exe_hdr.
- dbxread.c: ditto.
- core.c: initialize initialized data at compile time.
- (core_file_command): Move from coredep.c, convert to bfd.
- (xfer_core_file): Convert to bfd.

-
- * coredep.c: (fetch_core_registers) Convert core_file_command to
- fetch_core_registers.
- mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
-
- * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
- (my_bfd_read): More bogosity, which I don't think we call.
- (program_name): Remove this atrocity asap!
- Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
- * From Per Bothner:
- values.c: allocate_repeat_value was not clearing the
- optimized_out field.
- (value_static_field): minor stylistic fix (wrong macro was used).
- valops.c (value_struct_elt_for_address): didn't work for C++
- static fields.
- * signame.c (_initialize_signame): Initialize signal names once.
- * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
- exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
- symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
- * remote-eb.c: Support user-settable baud rates on the serial port.
- * tm-sun3.h (PREPARE_TO_STORE): fix typo.
- Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
- * tconfig/sun3os4: Remove warning about native assembler,
- since it also occurs in the xconfig file.
- * findvar.c (registers): Allocate some slop after `registers'
- to prevent stray accesses from trashing the next variable.
- * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
- on the sun-3, by changing the #ifdef from `sun3' (which is not
- defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
- vars, which happened to follow `registers' in the executable.
- * readline/history.c (history_search): Heed gcc-2's advice
- and parenthesize && inside ||).
- * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
- tm-29k.c: Insert FSF copyright headers.
- * remote-eb.c: Better comments.

- prev_* if the inferior no longer exists.
- * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
- CANNOT_EXECUTE_STACK.

- * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
- * inferior.h (PC_IN_CALL_DUMMY): New macro.
- infrun.c (wait_for_inferior, 2 places): Use it.
- * values.c (value_being_returned): Only use
- EXTRACT_STRUCT_VALUE_ADDRESS if defined.
- * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
- right thing for remote-eb.c.
- * sun3-xdep.c: Remove extraneous call to remote_store_registers.
- * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
- * blockframe.c: Put get_frame_saved_regs inside #if !defined
- (FRAME_FIND_SAVED_REGS).

- Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
- * coffread.c (read_one_sym): Make temp_aux an AUXENT, not

- coffread.c: #include <sys/stat.h>.
- (read_coff_symtab): Typo: in_source_files -> in_source_file.
- Add missing ')' in check for "lc%" and friends. Remove
- extraneous '}'.
- Declare read_one_sym() at top of file.
- (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
- MC68WRMAGIC can have the same value without causing a duplicate
- case.
- Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
- * Allow a Makefile to be built without building the
- tm and xm file links that screw up builds in subdirectories.
- This is done with `config.gdb none', then you can do things
- like `make gdb.tar.Z'.
- * tconfig/none: Config file for no target system
- * xconfig/none: Config file for no host system
- * config.gdb: If no TM or XM files are called out by the
- host or target file, don't make links for them.
- * cplus-dem.c: Add documentation.
- * dbxread.c (read_ofile_symtab): Turn a fatal error into a
- simple error, so the user's gdb doesn't crash due to some object
- file problem (e.g. somebody is rebuilding the file out from under
- gdb).
- * printcmd.c (print_address_symbolic): demangle the symbol.
- * Makefile.dist (OTHERS): Remove tdesc-lib because it has
- Motorola copyrights in it. Make "make gdb.tar.Z" work.
- (alldeps.mak): sort and uniq all results from this; duplicates
- hose gdb.tar.Z link building. Remove RCS files from
- tconfig and xconfig. Add config files for sun386. Add
- a few odd files to OTHERS and HFILES.
- Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
- * Makefile.dist: Pull solib.c to tconfig/sun?os4.
- Roll version number to 3.91.5. Make lint work in bindir.
- * README: Document cross-debugging and new file structure.
- * blockframe.c: Lint. Include "value.h" to declare read_register.
- (find_pc_partial_function): remove duplicate line.
- * command.h: Lint. Declare error_no_arg and dont_repeat.
- * tm-news.h: Remove inadvertently duplicated stuff.
- * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
- Clean up usage of misc_function_type. Declare some CORE_ADDRs.
- * config.gdb: Allow `config.gdb host target' form. Clean
- up previous change that printed bogus messages when you just said
- `config.gdb'.
- * core.c: #include "command.h" for lint.
- * dbxread.c: lint
- * eval.c: lint
- * main.c: Remove some casts of enums. Lint.

- * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
-
- * sparc-tdep.c (isannulled): Take instruction as parameter, don't
- read it from memory. This will allow us to save ptrace calls
- eventually. Changed caller single_step too.
- * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
- that we aren't going to use, saving many ptrace calls, especially
- when watchpointing or single stepping. Use some #define's for
- constants.
- (store_inferior_registers): Ditto.
- (core_file_command): Use some #define's for constants.
- * tm-sparc.h: Add #define's for some register numbers, so we
- can eliminate the use of random constants in sparc-xdep.c.
- * stack.c (frame_command, print_frame_info, up_command,
- down_command) Remove frame_changed, since it
- causes a bug and doesn't seem to do anything useful. In some
- places it was used as a flag, in others as a stack level (?).
- * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
- default is to use the portable (vprintf) version rather than the
- kludge version.
- * xm-news.h (MISSING_VPRINTF): Add.
- * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
- Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
- * Remove stuff that forces -Bstatic linking of gdb, and warnings
- about linking debugged programs -Bstatic in the sun?os4 config
- files in tconfig and xconfig subdirectories.
- * main.c (main): Remove unreached exit(0) now that we exit
- via quit_command().
- * Create TODO file for online bug list. There are too many
- "little" bugs to keep track of on paper.
- * Change Projects file to refer to bug-gdb@cygnus.com
- rather than kingdon@ai.
- Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
- * Makefile.dist (VERSION): 3.91.4 now.
- * symtab.c (init_misc_bunches): Rename from init_misc_functions.
- (condense_misc_bunches): Add sanity check that misc_count is
- the same as the number of symbols in the bunch.
-
- * coffread.c: rename init_misc_bunches. Pass an argument
- to condense_misc_bunches (a zero).
- * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
- every time we are called; don't rely on our caller to do it.
- (add_file): Remove call to init_misc_bunches.
- * mipsread.c: Only warn, don't error, if unknown symbol types.
- This keeps an old gdb from falling on its face if it sees newly
- extended symbol info. Rename init_misc_bunches.
- Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
- * Merge in changes from Per Bothner for DECstations and other
- MIPS stuff. The rest is Bothner speaking:
- The next message is a merger of Alessando Forin's mips port with
- mine. I've tried to use my good if biased judgment to get
- the best of both. It *does* need testing.
- Some of the changes are general, *not* mips-specific.
- param.h:
- Didn't believe in little-endian bit order.
- There are still inconsistencies about whether flags
- like BITS_BIG_ENDIAN are integer (#if ...) or
- boolean (#ifdef ...). I tried to paper over them.
- dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
- Moved some misc_function code that was common to
- {dbx,coff,mips}read.c to symtab.c.
- In the process, I think I cleaned things up a bit.
- At the same time, moved obsavestring and obconcat to symtab.c.
- dbxread.c:
- Removed obsolete condense_addl_misc_bunches (use
- condense_misc_bunches(1) instead).
- exec.c:
- Needed to include <sys/dir>, at least on DECstations.
- valops.c, mips-tdep.c, tm-mips.h:
- Added PUSH_ARGUMENTS macro to support funny argument-pushing
- conventions (when STACK_ALIGN is insufficient).
- Needed on mips, where doubles need 8-byte alignment,
- but ints only need 4.
- mips-opcode.h:
- Removed cruft that was not being used.
- Merged in many fixes (most from Frank Yellin, fy@lucid.com).
- mips-pinsn.c:
- Print $ before register-names (I think that makes things a little
- more consistent).
- Never print two instructions, even if one delays.
- Removed hex-disassemble set_cmd. (This is not mips-specific,
- so I think the argument is whether it is generally worthwhile or not.
- I'm inclined to think not, given how easy it is to
- convert between radixes in gdb.)
- mipsread.c:
- This is basically Alessando's code.
- It doesn't use obstacks; I changed it to use obstacks
- in a few minor places where using malloc causes a
- memory leak. (Probably, more places could/should be changed.)
- I added record_misc_function where it was missing.
- In symbol_file_command and add_file_command, I tried
- to make the code consistent with more recent versions.
- Minor sylistic changes in parse_procedure.
- Make a .gdbinfo. psuedo-symbol point back to the real
- procedure symbol (using the isym field).
- mips-tdep.c:
- This is basically from my port, but with a lot of details
- and a number of routines merged in from Alessando's version.
- I basically used my code "raw" backtrace (use heuristics
- from the actual code, rather than symbol table info) - though
- the idea is Alessandro's. I feel my code is a little cleaner
- here, particularly in being a little more flexible, such as being
- able to handle gcc-produced code (which it now can).
- It also doesn't do frame caching (which is not useful
- more recent gdb versions).
- I also used my code for push_/pop_dummy, more or less.
- I tried to incorporate AF's code for testing sigtramp
- while backtracing; I probably got it wrong.
- Added mips_print_register, which tries to scrunch as much
- information as possible on a screen...
- Removed the skip-prologue set_cmd. As with hex-disassemble (see
- under mips-pinsn.c), I don't see anything mips-specific here,
- and I don't see it being all that useful anyway.
-
- tm-mips.h:
- Added a $fp psuedo-reg distinct from $fp (nice for gcc).
- Use more register names (rather than hard-cases numbers).
-
- Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
- * Hack up 3.90.11 changes:
- * Makefile.dist (depend): parameterize $(GCC).
- Add solib.c and solib.o.
- (readline): Fix vpath for both absolute or relative SRCDIR.
- * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
- Also, let the part I didn't understand at least compile so
- I can test the rest. FIXME.
- * dbxread.c: Fix thinko using strcmp.
- (init_psymbol_list): declare static.
- (partial_symbol_file_open): Comment cleanups better, avoid
- cleaning up the string table since the caller will do that.
- Move the stat for mod time into symbol_file_command, temporarily.
- (There should be a mod time for each symbol file, eventually,
- to control its rereading. FIXME.)
- * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
- SunOS, which gives error for shared libs otherwise. (From
- Schaefer, probably FIXME needs work for portability.)
- * solib.c: Move #include "param.h" to work.
- Lowercase all the Uppercase Letters In the Messages.
- (find_solib): Clean up inferior_so_name for debug printouts.
- Allow no argument, to mean all shared libraries.
- * symmisc.c: include param.h to get CLEAR_SOLIB.

- copy a makefile into it.
- * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
- consistency with POSIX.
- * breakpoint.c (bpstat_stop_status): Disable watchpoint

- Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
- * Makefile.dist: Bump version to 3.91.3.
- * Clean up handling of breakpoint commands (somewhat).
- Prompted by Tiemann bug report "cont 10" doesn't work any more.
- inferior.h: Add breakpoint_proceeded to inferior status struct
- and globals; save it and restore it.
- (clear_breakpoint_commands): Cleanup, remove old #define.
- infrun.c (clear_proceed_status): Set breakpoint_proceeded.
- (save_inferior_status, restore_inferior_status): handle it also.
- (proceed): Remove earlier code that set breakpoint_proceeded.
- It is now set only in clear_proceed_status.
- (clear_proceed_status): Cleanup, use bpstat_clear rather
- than clear_breakpoint_commands. No callers need the stop_bpstat
- between clear_proceed_status and proceed.
- infcmd.c: Add breakpoint_proceeded definition and comment.
- (cont_command, jump_command, signal_command): Move call to
- clear_proceed_status right next to call to proceed.
- breakpoint.c (bpstat_do_actions): Avoid clobbering our
- caller's argument while running down the chain of breakpoints.
- Use new variable "breakpoint_proceeded" to determine when
- a command that it executes moves the inferior past the
- breakpoint.
- (bpstat_clear): Handle NULL argument.
- (bpstat_clear_actions): Avoid useless call to
- breakpoint_auto_delete.
- (delete_breakpoint): Clean up bpstat's that are pointing to
- the deleted breakpoint from the stop_bpstat chain.
- (breakpoint_auto_delete): Simplify.
- * Clean up handling of EOF, error on stdin, etc. This was
- prompted by a network problem that caused gdb to go into an
- infinite loop filling up its malloc'd memory.
- main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
- not clear_breakpoints_commands, which is now gone.
- (main): If command_loop returns (e.g. from EOF on stdin), do
- a quit_command (looping back to command_loop if quit_command
- doesn't really quit).
- (command_loop): check result from command_line_input and
- exit if it returns NULL, rather than passing the NULL to
- execute_command.
- (gdb_readline): Free malloc'd result space before returning
- NULL for EOF.
- * utils.c (query): Handle C-d to mean "yes", just as if the
- input was not a terminal. Also avoid infinite loop if EOF
- occurs in mid-input-line before newline. This allows
- query to be used at EOF on stdin with reasonable results.
- * infrun.c (proceed): Set breakpoint_proceeded.
- * values.c (value_as_long): Avoid infinite recursion for enums.
- (_initialize_values): Fix typo in help msg (kingdon).
- * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
- RL_LIB for linking. This allows -lreadline for linking
- and nothing for dependencies, once readline is a real library.
- * config.gdb: Jim Kingdon: give useful error message if the
- host or target type is not recognized.
- * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
- it just defines it. Dumb, but deal with it.
- * Jim Kingdon suggests:
- in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
- Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
- * Makefile.dist (VERSION): Bump version # to 3.91.2.
- * Clean up Bothner's changes.
- * blockframe.c (clear_pc_function_cache): New function.
- * blockframe.c: remake cache_pc_function_* static.
- * dbxread.c (symbol_file_command): remove references to
- cache_pc_function_* variables.
- * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
- * printcmd.c: Avoid kludging a global variable (addressprint)
- to avoid printing the address of a string twice. Instead,
- pass the format letter 's' down low enough that it can be seen
- to avoid this problem.
- (print_formatted): Pass format arg to value_print.
- (restore_addressprint): Remove function.
- (do_examine): Avoid hacking addressprint, cleanups and such.
- (print_frame_args): Add a comment to a Bothner change.
- * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
- * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
- to wipe out the values cached in blockframe.c.
- * symtab.c (find_method): Add comment saying how big you must
- allocate to be "big enough". Per being terse again.
- * valprint.c (val_print): Handle format letter "s" to print
- strings without addresses. Add comment to vtbl printing code
- which casts with wild abandon. Rearrange reference-printing
- code so it prints:
- @0xaddr: value (print w/addressprint)
- value (print w/~addressprint)
- @0xaddr (parameter lists w/addressprint)
- or nothing (parameter lists w/o addressprint)
- Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
- * Merge more changes from Per Bothner:
- Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
- annoying) that I tried to improve it. Here are my suggestions.
- These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
- findvar.c:
- Do automatic de-reference when taking the address of a reference.
- printcmd.c:
- Don't deref_ref when printing parameter lists.
- valops.c:
- More attempts at treating refernences properly.
- valprint.c:
- In val_print, if deref_ref==0, don't print dangling " = ".
- value.h:
- Add COERCE_REF macro, which de-references an REF.
- * Merge changes from Per Bothner:
- * Fixed (Sony news)-specific configuration problems.
- * Fixed other problems with using vanilla pcc and libc (enum problems;
- assumption that vsprintf exists).
- * Some major speed-ups (finc_pc_partial_function now caches a match;
- parsing avoids duplicate symbol_lookup calls).
- * Changed handling of baseclasses (no longer use baseclasses field
- of struct type, use the first n_baseclasses fields instead).
- * Various minor changes/fixes, most C++-related.
- blockframe.c:
- Cache the most previous match from find_pc_partial_function.
- (Save both low and high ends of matching function's pc range.)
- This speeds up the loop of infrun.c:wait_for_inferior quite
- a bit, and makes step/next commands much zippier.
- command.c:
- Added an enum->int cast (otherwise, some compilers barf).
- dbxread.c:
- No longer set baseclass offset to 0, since multiple
- inheritance now mostly works.
- Added a number of casts, to shut up compiler warnings
- (after stabs where made enums, not ints).
- When discarding a symbol table (in symbol_file_command),
- must clear the cache introduced in blockframe.c.
- Don't convert $vtbl_ptr_type to vtbl any more.
- Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
- Mask off sign bit emitted by g++ for virtual table offset.
- Set voffset to -1 (not 1) for static member functions.
- expread.y:
- Changed parsing/lexing of names to avoid doing symbol lookup twice
- (once when lexing to determine symbol class, once for real).
- Now only call symbol_lookup once. Fields of 'this' win especially big.
- printcmd.c:
- Subpress printing addr twice in the case of 'x/s addr'.
- symtab.c:
- lookup_basetype_type is no longer used.
- Add find_methods as recursive helper function to decode_line_1.
- This allows multiple inheritance to work.
- Also, once one or more matches has been found, do not look in
- base-classes. (Baseclass methods would be overridden, anyway.)
- symtab.h:
- Removed baseclasses array in struct type.
- Instead of using baseclasses[i], use fields[i-1].
- Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
- Changed sign convention of voffset (previous was inconsistent).
- tm-news.h:
- Some macros (CALL_DUMMY and relatives) were missing. Put them back.
- utils.c:
- Used to assume existence of vsprintf. Re-written to not need it
- if HAVE_VPRINTF is undefined.
- valops.c:
- typecmp was too pessimistic. Made it less so.
- valprint.c:
- Don't print space after address.
- If vtable points to a misc symbol (with 0 offset), print it,
- since that indicates the actual class of the object.
- Changed ype_print_derivation_info to use new inheritance
- scheme (without baseclasses vector).
- values.c:
- In value_primitive_field, fixed some bugs left over from previous set of fixes.
- Also, changes needed because TYPE_BASECLASSES were removed.
- xm-news.h:
- REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
- Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
- * source.c:
- If there is no path set, and the symbols don't indicate what directory
- a file was compiled in, look in the current directory. But either
- a path or a known compilation directory will prevent this.
- * dbxread.c:
- Three independent bug fixes:
- * Remove the #if 0 block that breaks some stuff.
- * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
- adapt gdb to either SunOS 4.0.* or 4.1.
- * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
-
- * symtab.c:
- Instantiate the class T when looking for methods in it. (Tiemann@sun)
- * valprint.c:
- (type_print) Demangle the name being printed.
- (type_print_base) Handle botched demangling without coredump (tiemann).
- * values.c:
- (check_stub_method): Document routine.
- (tiemann) fix bug for no-arg functions
- Avoid clobbering beyond end of malloc'd storage.
- Terminate the argument list properly.
- Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
- * Changes merged by John Gilmore:
-
- breakpoint.c:
- In breakpoint_1, use new print_address_symbolic instead
- of find_pc_partial_function. (This forces use of assembler-level
- addresses, and avoids misleading non-mangled source-level names.)
- cplus-dem.c:
- Generalize ansi argument such that -1 means skip arglist totally.
- Removed global variable print_ansi_qualifiers (which made
- code non-reentrant), in favor of extra explicit arguments
- to internal routines.
- printcmd.c:
- Add new helper function print_address_symbolic.
- Use find_pc_misc_function instead of find_pc_partial_function
- (since we want assembler-level symbols here).
- stack.c:
- Print unknown function as just "f (...)", not "f (...) (...)".
- Use new fputs_demangled explicitly.
- symtab.c:
- Fixed a typing violation (problem: value.h cannot be imported
- without renaming many variable in this file).
- lookup_symbol: If no matching misc_func, look for a C++-mangled name.
- decode_line_1: Moved forward some never-reached code.
- Made decode_line_2 skip function prologues correctly.
- utils.c:
- fputs_filtered should not demangle by default.
- Add new fputs_demangled to demangle on demand..
- valops.c:
- Change value_struct_elt to use value_primitive_field (using recursive
- utility function search_struct_field). This allows foo.bar to work
- for multiple inheritance (so far only for data fields).
- Change check_field in the same way (recursive helper function
- to support multiple inheritance).
- (Note: there are more of these problems that I haven't fixed.
- Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
- value_of_this: 'this' symbol name is now just "this", note "$this".
- valprint.c:
- Don't print static members.
- Avoid printing "members of <type>" if there are none.
- Simplified type_print_derivation_info by merging duplicate code.
- Remove useless blank lines in type_print_base (ptype command).
- value.h:
- Added declaration of new routine value_primitive_field.
- values.c:
- Added value_primitive_field which is generalized version of
- value_field that can handle multiple inheritance (non-zero offsets etc).
- Re-implemented value_field to call value_primitive_field.
- Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
- * infcmd.c -- insert else to avoid 'delete env' coredump when you
- delete the whole environment. Karl Berry reported the bug.
- * source.c - fix openp to avoid //'s in filenames, which
- trigger an Emacs bug causing it to not be able to find files
- when running gdb in a window.
- * dbxread.c - zap the #if 0 that botches the add-file code.
- It seems to work a lot better without all the code commented out.
- Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
- * Merge Tiemann's and Ted Goldstein's changes, detailed below,
- into gdb-3.90.9.
- Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
- * Makefile - added a ${CFLAGS} to a couple of entries,
- added remote-sa.sparc.c
- * added remote.sa-sparc.c, a modification of remote.c
- which conducts a dialog directly with the SparcStation prom.
- * breakpoint.c, infrun.c, sparcdep.c added
- remote_insert_breakpoint(), and remote_remove_breakpoint()
- to breakpoint.c instead of directly writing breakpoint instructions.
- * sparcdep.c on remote_debugging,there is no need
- to remove signle step breakpoint instructions.
- * main.c added "-epoch" flag and "int epoch_interface" to main.c
- global variable
- * printcmd.c - epoch interface sends lisp expressions to open up
- epoch windows on inspection.
- * valprint.c - added arrayprint, and addressprint and made adding
- format controls easier
- * wait.h added a couple of undef's because we were getting
- complaints about WSTOPSIG and WTERMSIG begin redefined.
- Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
- * symtab.c (decode_line_1): Add support for handling method stubs
- in the type information.
- Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
- * values.c (baseclass_addr): Run loop from INDEX+1 to
- N_BASECLASSES; otherwise, we can still get into a loop.
- @@ This should be restructured to use a cleaner search strategy.
- Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
- * dbxread.c (define_symbol,read_type): Grok GNU C++'s new

- the functions which match a particular regular expression.
- Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
- * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
- should print ANSI qualifiers (such as `const' and `volatile').
- All callers changed to call with ANSI == 1, except from
- `check_method_stub', which uses old-style syntax.
- * symseg.h (struct fn_field): Remove unneccessary `args' field.
- * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
- * values.c (check_stub_method): New function.
- * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').

- * valprint (type_print_base): Ditto.
- * symtab.c (gdb_mangle_typename): New function.
- Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
- * breakpoint.c (catch_command): New function. Provides a
- mechanism to set breakpoints based on catch clauses.
- (disable_catch): Similar, but disables breakpoints on catch
- clauses.
- (delete_catch): Similar, but deleted breakpoints on catch clauses.
- Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
- * blockframe.c (blockvector_for_pc): New function.
- * blockframe.c (block_for_pc): Changed to call
- `blockvector_for_pc' and get the block itself.
- * stack.c (catch_info): New function. Prints info about
- exceptions which can be caught in the current frame.
- * stack.c (print_frame_label_vars): New function. Similar to
- `print_frame_local_vars'.
- * stack.c (print_block_frame_labels): Prints out labels that are
- defined in this frame. These labels are exceptions that can be
- caught.
- * dbxread.c: Updated to handle N_CATCH symtab types.
- Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
- * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
- form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
- when printing the type.
- Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
- * valprint.c (val_print): Use `baseclass_addr' to access the
- baseclasses pointed to via the derived class object at VALADDR.
- * values.c (baseclass_addr): New function. Casts derived pointers
- to baseclass pointers taking virtual baseclasses and multiple
- inheritance into account.
- Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
- * Version 3.90.9.
- Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)

- exp_valid_block field correctly.
- * infrun.c (wait_for_inferior): When checking "don't even think
- about breakpoints" if stop_signal == SIGTRAP && trap_expected,
- also check step_resume_breakpoint.
- Insert breakpoints and continue (not step) if
- step_resume_break_address != NULL, even if another_trap.
- If trap_expected and we enter sigtramp, then set up a
- step_resume_break.
- If trap_expected is set when we hit the step_resume_break,
- set another_trap.
- When calling resume and trap_expected says tell resume to step
- (2 places), also check step_resume_break_address.
- * infrun.c (wait_for_inferior): Don't set
- prev_{pc,sp,func_{start,name}} before calling wait ().
- Do set them after exiting loop.
- Move their declarations outside functions.
- (start_inferior): Initialize them.
- Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
- * infrun.c (wait_for_inferior, after check for trap_expected > 1):
- Restore old code which distinguishes between trap_expected and
- running_in_shell, just make the latter take any non-TRAP signal,
- not just SEGV.
- * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
- * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
