Bug ID: 106344
Summary: A few x86_64 tests fail with -march=x86-64-v2
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: testsuite
Assignee: unassigned at gcc dot gnu.org
Reporter: mpolacek at gcc dot gnu.org
Target Milestone: ---
The following tests fail when -march=x86-64-v2 is the default:
gcc.dg/vect/bb-slp-57.c
gcc.dg/vect/slp-21.c
gcc.dg/vect/slp-perm-9.c
gcc.target/i386/minmax-9.c
gcc.target/i386/sse2-mmx-21.c
g++.target/i386/pr98218-1.C
Can be reproduced with:
$ make check-gcc RUNTESTFLAGS='--target_board=unix\{,-march=x86-64-v2\}
vect.exp=bb-slp-57.c'
$ make check-gcc RUNTESTFLAGS='--target_board=unix\{,-march=x86-64-v2\}
vect.exp=slp-21.c'
$ make check-gcc RUNTESTFLAGS='--target_board=unix\{,-march=x86-64-v2\}
vect.exp=slp-perm-9.c'
$ make check-gcc RUNTESTFLAGS='--target_board=unix\{,-march=x86-64-v2\}
i386.exp=minmax-9.c'
$ make check-gcc RUNTESTFLAGS='--target_board=unix\{,-march=x86-64-v2\}
i386.exp=sse2-mmx-21.c'
$ make check-g++ RUNTESTFLAGS='--target_board=unix\{,-march=x86-64-v2\}
i386.exp=pr98218-1.C'
Would there be a way to amend the tests so that they don't fail with
-march=x86-64-v2?
