Bug ID: 115517
Summary: Fix regression after dropping uses of
vcond{,u,eq}_optab
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: liuhongt at gcc dot gnu.org
Depends on: 114189
Target Milestone: ---
Target: x86_64-*-* i?86-*-*
> I'd appreciate testing, I do not expect fallout for x86 or arm/aarch64.
> > I know riscv doesn't implement any of the legacy optabs. But less
> > maintained vector targets might need adjustments.
> >
> At GCC14, I tried to remove these expanders in the x86 backend, and it
> regressed some testcases, mainly because of the optimizations we did
> in ix86_expand_{int,fp}_vcond.
> I've started testing your patch, it's possible that we still need to
> move the ix86_expand_{int,fp}_vcond optimizations to the
> middle-end(isel or match.pd)or add extra patterns to handle it at the
> rtl pas_combine.
These are new failures I got
