Ilja Iskovs a69080060d Reland "[arm64][wasm] Use NEON S/Usra for Wasm SIMD add(shr(x, imm), y)" ... This is a reland of 2261e05333 This patch can now be relanded as some space was made for more opcodes: https://bugs.chromium.org/p/v8/issues/detail?id=12093 Original change's description: > [arm64][wasm] Use NEON S/Usra for Wasm SIMD add(shr(x, imm), y) > > A single AArch64 SIMD signed/unsigned Shift Right and Accumulate can be > used to implement Wasm SIMD add(shr(x, imm), y). This gives a 1-1.5% > improvement on some compute intensive Wasm benchmarks on Neoverse-N1. > > Mla and Adalp optimisations were refactored to match the style of the > added code. > > Change-Id: Id5959a31ca267e02b7d60e7ff6f942adb029b41e > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3089157 > Reviewed-by: Zhi An Ng <zhin@chromium.org> > Commit-Queue: Martyn Capewell <martyn.capewell@arm.com> > Cr-Commit-Position: refs/heads/master@{#76280} Change-Id: Idd166b7d3c960af33049bbce6e7276763c28f286 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3097284 Commit-Queue: Martyn Capewell <martyn.capewell@arm.com> Reviewed-by: Zhi An Ng <zhin@chromium.org> Reviewed-by: Clemens Backes <clemensb@chromium.org> Cr-Commit-Position: refs/heads/master@{#76340}		2021-08-17 09:27:26 +00:00
