Type::getInt32Ty(M.getContext()) have a bug !!!

[xiaoxu1234]

Type *I32Ty = Type::getInt32Ty(M.getContext()); if (I32Ty->isIntegerTy()) { errs() << "xxx : I32Ty isIntegerTy\n"; } else if (I32Ty->isFunctionTy()) { errs() << "xxx : I32Ty isFunctionTy\n"; } else { errs() << "xxx : I32Ty isUnknown\n"; }

this code for I32Ty is FunctionTy, I32Ty should be isIntegerTy!!!

Reproduction steps as follows:
you can search llvm src LLVMPasses PassBuilderPipeLines.cpp, in this file has a lot of internel pass, you can find any one for module pass.

for example: Annotation2MetadataPass
PreservedAnalyses Annotation2MetadataPass::run(Module &M, ModuleAnalysisManager &AM) { Type *I32Ty = Type::getInt32Ty(M.getContext()); if (I32Ty->isIntegerTy()) { errs() << "xxx : I32Ty isIntegerTy\n"; } else if (I32Ty->isFunctionTy()) { errs() << "xxx : I32Ty isFunctionTy\n"; } else { errs() << "xxx : I32Ty isUnknown\n"; } convertAnnotation2Metadata(M); return PreservedAnalyses::all(); }

The Issue only happend in xcode(15 beta) clang, clang dir is /Applications/Xcode-beta.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang. if I compile the open source code clang ..llvm to test Type::getInt32Ty method, it is IntegerTy. Maybe Xcode15-beta2'clang have some problems.
