In this patch to haifa-sched.c:
Revision 1.90 / (download) - annotate - [select for diffs] , Wed Jul 21 01:15:46 1999 UTC (15 months ago) by rth
Branch: MAIN
Changes since 1.89: +91 -104 lines
Diff to previous 1.89 (colored)
* haifa-sched.c (insn_cost): FREE implies cost 0 and vice versa.
(adjust_priority): Always call ADJUST_PRIORITY.
(schedule_insn): Only put insns into the ready at cost 0.
(schedule_block): Remove redundant initial sort. Give clock_var
and can_issue_more to MD_SCHED_REORDER. Requeue if hazard cost
is not 0.
* tm.texi (MD_SCHED_REORDER): Update docs.
* sparc.h (MD_SCHED_REORDER): Update. Set CAN_ISSUE_MORE.
* sparc.c (ultra_reorder_called_this_block): Delete.
(ultrasparc_sched_init): Don't set it.
(ultrasparc_sched_reorder): Don't check it.
rth initialized clock_var to -1 instead of 0 in each block, but he
didn't change the way that total cycles/block are reported in the
.c.sched and .c.sched2 files. I think the following change more
accurately reflects the number of cycles each block takes:

* haifa-sched.c (schedule_block): Increment clock_var by one when
reporting total clocks/basic block.
