Author: bernds Date: Fri Jul 16 23:47:46 2010 New Revision: 162270 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=162270 Log: PR target/42235 * postreload.c (reload_cse_move2add): Return bool, true if anything. changed. All callers changed. (move2add_use_add2_insn): Likewise. (move2add_use_add3_insn): Likewise. (reload_cse_regs): If reload_cse_move2add changed anything, rerun reload_combine. (RELOAD_COMBINE_MAX_USES): Bump to 16. (last_jump_ruid): New static variable. (struct reg_use): New members CONTAINING_MEM and RUID. (reg_state): New members ALL_OFFSETS_MATCH and REAL_STORE_RUID. (reload_combine_split_one_ruid, reload_combine_split_ruids, reload_combine_purge_insn_uses, reload_combine_closest_single_use reload_combine_purge_reg_uses_after_ruid, reload_combine_recognize_const_pattern): New static functions. (reload_combine_recognize_pattern): Verify that ALL_OFFSETS_MATCH is true for our reg and that we have available index regs. (reload_combine_note_use): New args RUID and CONTAINING_MEM. All callers changed. Use them to initialize fields in struct reg_use. (reload_combine): Initialize last_jump_ruid. Be careful when to take PREV_INSN of the scanned insn. Update REAL_STORE_RUID fields. Call reload_combine_recognize_const_pattern. (reload_combine_note_store): Update REAL_STORE_RUID field. * gcc.target/arm/pr42235.c: New test. Added: trunk/gcc/testsuite/gcc.target/arm/pr42235.c Modified: trunk/gcc/ChangeLog trunk/gcc/postreload.c trunk/gcc/testsuite/ChangeLog -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42235
