Subject: [WebAssembly] Delete an unnecessary line in RegStackify
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=03b93e4a1a1000d36cbc6abb36d6e269c8f0d32a;p=llvm

[WebAssembly] Delete an unnecessary line in RegStackify

`OneUseInst` is set outside of the loop before and `OneUse` does not
change throughout the loop, so this line is not necessary.
