            Bug ID: 102907
           Summary: aarch64/shrn-combine-[123].c fail with SVE
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal

  Target Milestone: ---

Hi Tamar,
I have noticed that the new tests shrn-combine-[123].c fail when running the
tests with -march=armv8.3-a+sve:
PASS: gcc.target/aarch64/shrn-combine-1.c (test for excess errors)
gcc.target/aarch64/shrn-combine-1.c: \\tshrn\\t found 0 times
FAIL: gcc.target/aarch64/shrn-combine-1.c scan-assembler-times \\tshrn\\t 1

PASS: gcc.target/aarch64/shrn-combine-2.c (test for excess errors)

FAIL: gcc.target/aarch64/shrn-combine-3.c scan-assembler-times \\tshrn2\\t 1

(and similarly with -march=armv8.5-a+sve2)

I haven't checked the actual generated code.
