alexcrichton opened PR #10457 from alexcrichton:x64-add-128
to bytecodealliance:main
:
If the two halves are both zero-extended 64-bit numbers then an
adc
instruction can be skipped in favor of asetb
which is predicted to be a bit easier on the CPU. Still not necessarily the best codegen but hopefully a tiny bit better than before.<!--
