arm: Auto-vectorization for MVE: vorr
This patch enables MVE vorrq instructions for auto-vectorization. MVE vorrq insns in mve.md are modified to use ior instead of unspec expression to support ior<mode>3. The ior<mode>3 expander is added to vec-common.md 2020-12-03 Christophe Lyon <christophe.lyon@linaro.org> gcc/ * config/arm/iterators.md (supf): Remove VORRQ_S and VORRQ_U. (VORRQ): Remove. * config/arm/mve.md (mve_vorrq_s<mode>): New entry for vorr instruction using expression ior. (mve_vorrq_u<mode>): New expander. (mve_vorrq_f<mode>): Use ior code instead of unspec. * config/arm/neon.md (ior<mode>3): Renamed into ior<mode>3_neon. * config/arm/predicates.md (imm_for_neon_logic_operand): Enable for MVE. * config/arm/unspecs.md (VORRQ_S, VORRQ_U, VORRQ_F): Remove. * config/arm/vec-common.md (ior<mode>3): New expander. gcc/testsuite/ * gcc.target/arm/simd/mve-vorr.c: Add vorr tests.
