Avoid this by masking the constant during assembly generation. The same applies to vorrq_n and vmvnq_n. gcc/ChangeLog: PR target/122175 * config/arm/iterators.md (asm_const_size): New mode attr. * config/arm/mve.md (@mve_<mve_insn>q_n_<supf><mode>): Use it. gcc/testsuite/ChangeLog: PR target/122175 * gcc.target/arm/mve/intrinsics/pr122175.c: New test.
