alexcrichton opened PR #6606 from alexcrichton:x64-sse2-pshufb
to bytecodealliance:main
:

's functionality at all where possible or otherwise fall back to a new libcall. This particular instruction seemed uniquely difficult to implement in the backend so I decided to "cop out" and use libcall instead. The libcall will be used forpopcnt
,shuffle
, andswizzle
instructions when SSSE3 isn't available.<!--
