(strength_reduce): Correct comments. Don't set maybe_multiple when pass branch to scan_start. Don't set not_every_iteration after passing a CODE_LABEL, or after passing a branch out of the loop. When outputting DEST_ADDR giv increments, put them next to the memory address on machines with auto-increment addresses. (record_biv): Set new field always_executed. (record_giv): Set new fields always_executed and auto_inc_opt. (maybe_eliminate_biv_1): Reject biv with auto_inc_opt optimization in some cases. From-SVN: r11090 |
