emilio created this revision.
Herald added a reviewer: jdoerfert.
Herald added projects: clang, LLVM.
Herald added subscribers: llvm-commits, cfe-commits.
Sign-extension is not guaranteed by the ABI, and thus the callee cannot assume
it.
This fixes PR44228 and PR12207.
With these changes, there are still two tests that need updating:
- CodeGenObjC/optimized-setter.m fails with:
clang: llvm/lib/IR/Instructions.cpp:400: void
llvm::CallInst::init(llvm::FunctionType *, llvm::Value *, ArrayRef<llvm::Value
*>, ArrayRef<llvm::OperandBundleDef>, const llvm::Twine &): Assertion `(i >=
FTy->getNumParams() || FTy->getParamType(i) == Args[i]->getType()) && "Calling
a function with a bad signature!"' failed.
- OpenMP/parallel_for_simd_codegen.cpp fails with:
clang: clang/lib/CodeGen/CGCall.cpp:3858: clang::CodeGen::RValue
clang::CodeGen::CodeGenFunction::EmitCall(const clang::CodeGen::CGFunctionInfo
&, const clang::CodeGen::CGCallee &, clang::CodeGen::ReturnValueSlot, const
clang::CodeGen::CallArgList &, llvm::CallBase **, clang::SourceLocation):
Assertion `IRFuncTy == TypeFromVal' failed.
These two are probably bad assumptions in some of the ObjC / OpenMP-specific
code, but I want to check this patch is on the right track before digging more.
