it unlocks many cool features!
- commits to ignore:
- - remove VMS stuff (not related to compiling)
- - misc cleanup (seems like a lot of debug removal)
- - remove g++ test cases (g++ doesn't exist anymore in agbcc)
- - remove static constuctors/destructors (some decorator)
- - remove more objc stuff (unrelated to C compilation)
- - remove live ranges (seems like non-default compiler flag, not documented in gcc 2.95.3 docs)
- - remove standalone preprocessor (cpp provided with modern gcc for compiling agbcc)
- - clean up limits.h (related to max value of something (e.g. maxint), doesn't seem related to compiling)
- - clean up standard headers (unrelated to arm compilation)
- - remove use of strings.h (refactoring via replacement of strings.h functions with library functions)
- - rely on configure less (refactoring some printing stuff which is probably tied to configure)
- - remove alternate versions of thumb files (!! check this out later)
- - clean up thumb code (!! check this out later)
- - clean up thumb.c more (!! check this out later, mostly looks like formatting fixes but thumb_exit was modified)
- - remove unneeded function (small commit, only removes some clearly unused code)
- - fix md (main change seems to be https://github.com/pret/agbcc/commit/ee6378488b6ef2654dcbffaaf1319c415c552f27#diff-1cff883ac32be6938d71c9a7da05004fL1101 , everything else looks like exit code replacements)
- - remove unused files (seems like they weren't used at all)
- - remove unused simple return code (removed code only defined through undefined cpp flags)
- - remove delay slot and stack reg code (unused by arm?)
- - remove epilogue delay list (! current_function_epilogue_delay_list is actually used in arm.c, look at this later)
- - remove PIC (non-working and disabled) (non-working and disabled)
- - remove macros for old compilers (removes undefined cpp flags, very small commit)
- - remove insn scheduling (not supported with thumb) (!!! supported with arm, need to re-add)
- - remove more unused files (removes some c compiler tests)
- - remove old version of loop.c (removes old version (loop_[date].c))
- - remove some hard reg ifdefs (!!! removed REG_ALLOC_ORDER, and CONDITIONAL_REGISTER_USAGE)
- - clean up more reg ifdefs (!!! removed HARD_FRAME_POINTER_REGNUM, PUSH_ROUNDING, hard_frame_pointer_rtx)
- - remove exit_ignore_stack ifdefs (!!! removed EXIT_IGNORE_STACK, clear_pending_stack_adjust)
- - kill libiberty (only touches gcc stuff irrelevant to arm compilation)
- - trim makefile (unrelated to arm compilation)
- - remove more files (replace assert.h with <assert.h>, doprint.c, dostage2, dostage3, remove some dwarf debugging stuff)
- - get rid of PROTO macros (only removes PROTO macros (I hope))
- - remove ANSI_PROTOTYPES ifdefs (ANSI_PROTOTYPES is defined by default)
- - get rid of VA_START macro (VA_START -> va_start)
- - get rid of PTR macros (NULL_PTR -> NULL, GENERIC_PTR -> void *)
- - stop using configure script to generate header files (configure related)
- - delete xm-i386.h (build/Makefile related)
