[PATCH] D76140: [InlineFunction] update attributes during inlining

[Anna Thomas via Phabricator via llvm-commits]

anna added a comment.

I got a failure in one of the binaryFormats:
lib/BinaryFormat/CMakeFiles/LLVMBinaryFormat.dir/MsgPackReader.cpp

  Attributes 'zeroext and signext' are incompatible!
    %rev.i.i.i.i.i.i.i.i = tail call signext zeroext i16 @llvm.bswap.i16(i16 %ret.0.copyload.i.i.i.i) #6
  in function _ZN4llvm7msgpack6Reader7readIntIsEENS_8ExpectedIbEERNS0_6ObjectE
  fatal error: error in backend: Broken function found, compilation aborted!

I believe this just showcases undefined behaviour since we were having a returnValue (i.e. call) with an incomptable attribute compared to the return attribute on the callsite.
