[PATCH] D101806: [TargetLowering] Only inspect attributes in the arguments for ArgListEntry

[Reid Kleckner via Phabricator via llvm-commits]

rnk added a comment.

The test failures are from the libfuzzer tests, which suggests that the coverage instrumentation pass has the same problem that msan had. I see an instance of the ZExt attribute there, that doesn't match the call site:
https://github.com/llvm/llvm-project/blob/main/llvm/lib/Transforms/Instrumentation/SanitizerCoverage.cpp#L428

The call site doesn't appear to set the attribute appropriately:
https://github.com/llvm/llvm-project/blob/main/llvm/lib/Transforms/Instrumentation/SanitizerCoverage.cpp#L888

Just a wild guess.
