------- Comment #12 from amacleod at redhat dot com 2006-04-26 18:59 ------- I have a patch to change the implementation of immediate uses forthcoming which, as a side effect, cleans up the operand scanner time in this file:
on my x86 cross powerpc64: before patch: tree operand scan : 366.20 (31%) usr 2.59 (18%) sys 371.20 (31%) wall TOTAL :1177.57 14.10 1200.53 after patch: tree operand scan : 3.07 ( 0%) usr 1.72 (12%) sys 4.69 ( 1%) wall TOTAL : 829.50 14.13 866.35 I will also take a look at the out-of-ssa time and see what can be done. Part of the problem there is a conflict graph is being built with 650,000,000 conflicts... thats not condusive to fast compile times! Thats a lot of SSA_NAMe version of a base variable!!!! -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26854
