alexcrichton opened PR #9201 from alexcrichton:aarch64-wide-mul to bytecodealliance:main:

This commit adds a special case to the lowering of 128-bit multiplication on the aarch64 backend along the same lines as was done in #9136 for the x64 backend. Notably zero and sign-extended values which are multiplied to produce a 128-bit result can skip some of the arithmetic of the fully general 128-bit lowering.
