            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 t=
hem
to be optimized away though.  But the generated code is correct.=
