------- Additional Comments From amylaar at gcc dot gnu dot org 2005-02-21 16:38 ------- While merging the patch in a 3.4.3 based branch, I noticed three small issues:
- The rest_of_handle_life prototype in passes.c is not necessary. It is a vestige from a previous (more intrusive) attempt to provide life information to if_convert. - In passes.c:rest_of_handle_if_conversion, at the end of the flag_expensive_optimizations code, EXIT_BLOCK_PTR->global_live_at_start has to be cleared for compatibility with this patch: 2004-05-17 J"orn Rennecke <[EMAIL PROTECTED]> * cse.c (trivially_dead_nonlocal_regs): New variable. (note_dead_set): New function. (delete_trivially_dead_insns): If life info is available, update it. For completeness, we might also clear ENTRY_BLOCK_PTR->global_live_at_end. - config/pa/pa.c:pa_commutative_p is missing the parameter list: (rtx x, int outer_code) -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20070
