--- Comment #7 from Roman Zhuykov <zhroma at ispras dot ru> --- (In reply to Jakub Jelinek from comment #5) > insufficient SMS testsuite coverage. Not sure it's helpful, but 3 weeks ago I succesfully reg-strapped some bunch of my SMS patches including this fix on x86-64 and aarch64 using trunk 20151222. fmodulo-sched and fmodulo-sched-allow-regmoves options were enabled by default, fsched-pressure left untouched. No new regressions, excluding some scan-assembler-times failures because of loop versioning. Maybe later on stage1 I'll send all my stuff to gcc-patches.
