From: Jonathan Wright Date: Mon, 11 Jan 2021 17:52:45 +0000 (+0000) Subject: aarch64: Use RTL builtins for integer mls intrinsics X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d2201ac0df461cb97a0187afc230029a6790b70e;p=gcc.git aarch64: Use RTL builtins for integer mls intrinsics Rewrite integer mls Neon intrinsics to use RTL builtins rather than inline assembly code, allowing for better scheduling and optimization. gcc/Changelog: 2021-01-11 Jonathan Wright * config/aarch64/aarch64-simd-builtins.def: Add mls builtin generator macro. * config/aarch64/arm_neon.h (vmls_s8): Use RTL builtin rather than asm.
