[LLVMdev] [LLVMLinux] Regression since r209049/r209065
Hi ! Since r209049, the build breaks with an ICE which r209065 did not fix: build of r209049: http://buildbot.llvm.linuxfoundation.org/builders/2_llvm/builds/58 build of r209065: http://buildbot.llvm.linuxfoundation.org/builders/2_llvm/builds/63 0 clang-3.5 0x0000000000d96c12 llvm::sys::PrintStackTrace(_IO_FILE*) + 34 1 clang-3.5 0x0000000000d967c4 2 libpthread.so.0 0x00002b304e0d1340 3 clang-3.5 0x0000000000b41250 llvm::CompositeType::getTypeAtIndex(llvm::Value const*) + 32 4 clang-3.5 0x0000000000b9b586 5 clang-3.5 0x0000000000b9fbd3 6 clang-3.5 0x0000000000ba01be 7 clang-3.5 0x0000000000b326ff llvm::FPPassManager::runOnFunction(llvm::Function&) + 623 8 clang-3.5 0x0000000000b3278b llvm::FPPassManager::runOnModule(llvm::Module&) + 43 9 clang-3.5 0x0000000000b34b15 llvm::legacy::PassManagerImpl::run(llvm::Module&) + 709 10 clang-3.5 0x00000000012cfcd0 clang::EmitBackendOutput(clang::DiagnosticsEngine&, clang::CodeGenOptions const&, clang::TargetOptions const&, clang::LangOptions const&, llvm::StringRef, llvm::Module*, clang::BackendAction, llvm::raw_ostream*) + 3008 11 clang-3.5 0x00000000012cafe9 12 clang-3.5 0x00000000016120db clang::ParseAST(clang::Sema&, bool, bool) + 507 13 clang-3.5 0x0000000000ee0ee6 clang::FrontendAction::Execute() + 134 14 clang-3.5 0x0000000000ec2af0 clang::CompilerInstance::ExecuteAction(clang::FrontendAction&) + 288 15 clang-3.5 0x0000000000f493e1 clang::ExecuteCompilerInvocation(clang::CompilerInstance*) + 1745 16 clang-3.5 0x000000000075e948 cc1_main(char const**, char const**, char const*, void*) + 984 17 clang-3.5 0x0000000000744a29 main + 8601 18 libc.so.6 0x00002b304ed39ec5 __libc_start_main + 245 19 clang-3.5 0x000000000075cf89 Stack dump: 0.

Could this have unearthed a latent bug?
for (unsigned J = 0, F = Op1->getNumOperands(); J != F; ++J) {
+ if (Op1->getOperand(J)->getType() !=
Op2->getOperand(J)->getType())
+ return nullptr;
cheers,
