alexcrichton opened PR #13462 from alexcrichton:x64-more-vptest to bytecodealliance:main:

This commit handles a few more patterns that the ptest instruction can be used for on x64, notably when testing v128 values for equality. This additionally handles cases where v128.and'd values are used for a branch which is naturally handled by the ptest instruction, too.

Closes #13405
