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.
