Bug ID: 102907
Summary: aarch64/shrn-combine-[123].c fail with SVE
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: clyon at gcc dot gnu.org
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

(and similarly with -march=armv8.5-a+sve2)
I haven't checked the actual generated code.
