abrown opened PR #2713 from memory_lane_access
to main
:
The Wasm SIMD specification has added new instructions that allow inserting to the lane of a vector from a memory location, and conversely, extracting from a lane of a vector to a memory location. The simplest implementation lowers these instructions,
load[8|16|32|64]_lane
andstore[8|16|32|64]_lane
, to a sequence of eitherload + insertlane
orextractlane + store
(in CLIF). With the new backend's pattern matching, we expect these CLIF sequences to compile as a single machine instruction (at least in x64).<!--
