Bug ID: 101206
Summary: [12 Regression] gcc.target/aarch64/vect-vmaxv.c and
gcc.target/aarch64/vect-vaddv.c fail
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: testsuite
Assignee: unassigned at gcc dot gnu.org
Reporter: pinskia at gcc dot gnu.org
Target Milestone: ---
Target: aarch64
These testcases fail:
FAIL: gcc.target/aarch64/vect-vmaxv.c scan-assembler umaxv\\tb[0-9]+,
v[0-9]+.16b
FAIL: gcc.target/aarch64/vect-vmaxv.c scan-assembler uminv\\tb[0-9]+,
v[0-9]+.16b
FAIL: gcc.target/aarch64/vect-vaddv.c scan-assembler addv\\tb[0-9]+,
v[0-9]+.16b
But they are failing because the above instructions that were in the
scan-assembler are now optimized away.
They are optimized in *r.dse1 I have not looked into what revision caused them
to be optimized away though. But the generated code is correct.
