This is due to a bug in the iterator used for the vashr and vlshr patterns in aarch64-simd.md. 2021-08-09 Tejas Belagod <[email protected]> gcc/ChangeLog PR target/101609 * config/aarch64/aarch64-simd.md (vlshr<mode>3, vashr<mode>3): Use the right iterator. gcc/testsuite/ChangeLog * gcc.target/aarch64/vect-shr-reg.c: New testcase. * gcc.target/aarch64/vect-shr-reg-run.c: Likewise.
