- # This BUILD_CONFIG option is a bit like bootstrap-debug, but rather
- # than comparing stripped object files, it compares compiler internal
- # state during stage3. Both can be used simultaneously.
- # This makes it slower than bootstrap-debug alone, for there's
- # additional dumping and recompilation during stage3.
- # bootstrap-debug-big can avoid the recompilation, if plenty of disk
- # space is available.
