[PATCH] D152495: [Clang][SemaCXX] Add unused warning for variables declared in condition expressions

[Takuya Shimizu via Phabricator via cfe-commits]

hazohelet added a comment.

I reverted this change because it broke sanitizer buildbots.
https://lab.llvm.org/buildbot/#/builders/19/builds/18369
The cause of the errors here are relatively clear and I can speculatively replace `if (std::error_code EC = makeCanonical(Path))` with `if (makeCanonical(Path))`

https://lab.llvm.org/buildbot/#/builders/94/builds/15865
https://lab.llvm.org/buildbot/#/builders/240/builds/12947
These 2 are not clear for me, so I'll take time to find the cause.
