- /* XCOFF archive support. The original version of this code was by
- Damon A. Permezel. It was enhanced to permit cross support, and
- writing archive files, by Ian Lance Taylor, Cygnus Support.
- XCOFF uses its own archive format. Everything is hooked together
- with file offset links, so it is possible to rapidly update an
- archive in place. Of course, we don't do that. An XCOFF archive
- has a real file header, not just an ARMAG string. The structure of
- the file header and of each archive header appear below.
- An XCOFF archive also has a member table, which is a list of
- elements in the archive (you can get that by looking through the
- linked list, but you have to read a lot more of the file). The
- member table has a normal archive header with an empty name. It is
- normally (and perhaps must be) the second to last entry in the
- archive. The member table data is almost printable ASCII. It
- starts with a 12 character decimal string which is the number of
- entries in the table. For each entry it has a 12 character decimal
- string which is the offset in the archive of that member. These
- entries are followed by a series of null terminated strings which
- are the member names for each entry.
- Finally, an XCOFF archive has a global symbol table, which is what
- we call the armap. The global symbol table has a normal archive
- header with an empty name. It is normally (and perhaps must be)
- the last entry in the archive. The contents start with a four byte
- binary number which is the number of entries. This is followed by
- a that many four byte binary numbers; each is the file offset of an
- entry in the archive. These numbers are followed by a series of
- null terminated strings, which are symbol names.
- AIX 4.3 introduced a new archive format which can handle larger
- files and also 32- and 64-bit objects in the same archive. The
- things said above remain true except that there is now more than
- one global symbol table. The one is used to index 32-bit objects,
- the other for 64-bit objects.
- The new archives (recognizable by the new ARMAG string) has larger
- field lengths so that we cannot really share any code. Also we have
- to take care that we are not generating the new form of archives
- on AIX 4.2 or earlier systems. */
- /* PR 21786: The PE/COFF standard does not require NUL termination for any of
- the ASCII fields in the archive headers. So in order to be able to extract
- numerical values we provide our own versions of strtol and strtoll which
- take a maximum length as an additional parameter. Also - just to save space,
- we omit the endptr return parameter, since we know that it is never used. */

- /* This is the relocation function for the RS/6000/POWER/PowerPC.
- This is currently the only processor which uses XCOFF; I hope that
- will never change.
- The original version was based on two documents:
- the PowerPC AIX Version 4 Application Binary Interface, First
- Edition (April 1992), and the PowerOpen ABI, Big-Endian
- 32-Bit Hardware Implementation (June 30, 1994). Differences
- between the documents are noted below.
- Now, IBM has released an official documentation about XCOFF
- format:
- https://www.ibm.com/support/knowledgecenter/ssw_aix_72/filesreference/XCOFF.html
- Unsupported r_type's
- R_RTB:
- R_RRTBI:
- R_RRTBA:
- These relocs are defined by the PowerPC ABI to be
- relative branches which use half of the difference
- between the symbol and the program counter. I can't
- quite figure out when this is useful. These relocs are
- not defined by the PowerOpen ABI.
- Supported r_type's
- R_POS:
- Simple positive relocation.
- R_NEG:
- Simple negative relocation.
- R_REL:
- Simple PC relative relocation.
- R_TOC:
- TOC relative relocation. The value in the instruction in
- the input file is the offset from the input file TOC to
- the desired location. We want the offset from the final
- TOC to the desired location. We have:
- isym = iTOC + in
- iinsn = in + o
- osym = oTOC + on
- oinsn = on + o
- so we must change insn by on - in.
- This relocation allows the linker to perform optimizations
- by transforming a load instruction into a add-immediate
- when possible. The relocation is, then, changed to R_TRLA
- in the output file.
- TODO: Currently, the optimisation isn't implemented.
- R_TRL:
- TOC relative relocation. Same as R_TOC, except that
- the optimization isn't allowed
- R_TRLA:
- TOC relative relocation. This is a TOC relative load
- address instruction which have been changed to an add-
- immediate instruction.
- R_GL:
- GL linkage relocation. The value of this relocation
- is the address of the external symbol in the TOC
- section.
- R_TCL:
- Local object TOC address. I can't figure out the
- difference between this and case R_GL.
- R_RL:
- The PowerPC AIX ABI describes this as a load which may be
- changed to a load address. The PowerOpen ABI says this
- is the same as case R_POS.
- R_RLA:
- The PowerPC AIX ABI describes this as a load address
- which may be changed to a load. The PowerOpen ABI says
- this is the same as R_POS.
- R_REF:
- Not a relocation but a way to prevent the garbage
- collector of AIX linker to remove symbols.
- This is not needed in our case.
- R_BA:
- The PowerOpen ABI says this is the same as R_RBA.
- R_RBA:
- Absolute branch which may be modified to become a
- relative branch.
- R_BR:
- The PowerOpen ABI says this is the same as R_RBR.
- R_RBR:
- A relative branch which may be modified to become an
- absolute branch.
- R_CAI:
- The PowerPC ABI defines this as an absolute call which
- may be modified to become a relative call. The PowerOpen
- ABI does not define this relocation type.
- R_CREL:
- The PowerPC ABI defines this as a relative call which may
- be modified to become an absolute call. The PowerOpen
- ABI does not define this relocation type.
- R_RBAC:
- The PowerPC ABI defines this as an absolute branch to a
- fixed address which may be modified to an absolute branch
- to a symbol. The PowerOpen ABI does not define this
- relocation type.
- R_RBRC:
- The PowerPC ABI defines this as an absolute branch to a
- fixed address which may be modified to a relative branch.
- The PowerOpen ABI does not define this relocation type.
- R_TLS:
- Thread-local storage relocation using general-dynamic
- model.
- R_TLS_IE:
- Thread-local storage relocation using initial-exec model.
- R_TLS_LD:
- Thread-local storage relocation using local-dynamic model.
- R_TLS_LE:
- Thread-local storage relocation using local-exec model.
- R_TLSM:
- Tread-local storage relocation used by the loader.
- R_TLSML:
- Tread-local storage relocation used by the loader.
- R_TOCU:
- Upper TOC relative relocation. The value is the
- high-order 16 bit of a TOC relative relocation.
- R_TOCL:
- Lower TOC relative relocation. The value is the
- low-order 16 bit of a TOC relative relocation.
