Bug ID: 101560
Summary: ICE building 526.blender_r with -Ofast -flto
-march=znver2 since r12-1958-gedafb35bdad
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: jamborm at gcc dot gnu.org
CC: hjl at gcc dot gnu.org
Target Milestone: ---
Host: x86_64-linux
Target: x86_64-linux
When building SPEC 2017 FPrate benchmark 526.blender_r with -Ofast -g
-flto -march=znver2 -mtune=znver2 I see the following ICE:
blender/source/blender/blenloader/intern/readfile.c: In function 'do_versions':
blender/source/blender/blenloader/intern/readfile.c:7595:1: internal compiler
error: in lra_assign, at lra-assigns.c:1649
7595 | }

Please submit a full bug report...
Note that the assert is triggered only with checking, so release-build
compilers do not see it.
I have bisected it down to:
commit edafb35bdadf309ebb9d1eddc5549f9e1ad49c09
Author: H.J. Lu <hjl.tools@gmail.com>
Date: Wed Jun 2 07:15:45 2021 -0700
x86: Convert CONST_WIDE_INT/CONST_VECTOR to broadcast
1. Update move expanders to convert the CONST_WIDE_INT and CONST_VECTOR
operands to vector broadcast from an integer with AVX.
2. Add ix86_gen_scratch_sse_rtx to return a scratch SSE register which
won't increase stack alignment requirement and blocks transformation by
the combine pass.
[...rest of the commit message trimmed...]
At this point I do not plan to attempt to come up with a reduced
testcase.

Might be the same as PR 101504 even.

I can confirm the patch avoids the ICE.
