similar to: [LLVMdev] InstVisitor: RetType

Thanks for providing me with those examples. My rather inefficient pass, which inherits from ModulePass, currently iterates through the Module, Functions, and BasicBlocks multiple times (once to find strcpy, another to find strcat, and so on for various other functions). If I only care about the direct calls, would I benefit more from switching to multiple use_iterators or the InstVisitor

Hi.All I had a problem in using llvm::InstVisitor class, my pass is like that: using namespace llvm; namespace { class InstVisit : public ModulePass, public InstVisitor<InstVisit> { public : static char ID; InstVisit():ModulePass(ID){} virtual bool runOnModule(Module &M) { visit(M); return false; } void visitStoreInst(StoreInst &SI) {

I just read the LLVM Programmer's Manual, which mentions (but specifically does not include any details of) the InstVisitor template. Could someone please provide an example of how to use this template to find (as an example) all CallSites for the function strcpy? Thanks, Brice Lin

Hi, I tried creating intrinsics which are to be placeholders for a set of instructions which should not be executed by the backend. I want to retain only intrinsic,phi and terminator instructions in a basic block. I have taken care of the external dependencies of basic block. How do I delete the rest of the instructions? Thank You Aditya P.S:

Hi, The checking about that if this is a terminator that it is at the end of the block has been applied twice (bellow). One is at Verifier::visitInstruction, and the other is at Verifier::visitTerminatorInst. Since visitInstruction is called when visiting each instruction, the checking at visitTerminatorInst seems redundant to me. Did I miss any case? void Verifier::visitInstruction(Instruction

Hello Pedro, As others have said we're assuming that you're using Clang as the frontend, the MSP430TargetInfo class inside lib/Basic/Targets.cpp (clang codebase) set ints to be 16 bits wide, so you should get 16bit mults straight away without promotion. But anyways for 8bit multiplicantions you can do the following to bypass argument promotion: 1) go to the lib/CodeGen/TargetInfo.cpp

The various intrinsic assert/crashes should all be fixed on mainline CVS (they are PR733, which I just fixed). The only ones that I'm wary of are: XPASS: /proj/llvm/build/../llvm/test/Regression/CFrontend/2004-02-20- StaticRedeclare.c.tr FAIL: /proj/llvm/build/../llvm/test/Regression/CFrontend/2005-12-04- DeclarationLineNumbers.c: In the former case, I would guess that the test isn't

Hi, Inserting a call instruction is a bit of a pain. The only way I know how to do it is to write a bunch of code like the following: std::vector<const Type*> formalArgs; formalArgs.push_back(arg1->getType()); formalArgs.push_back(arg2->getType()); ... formalArgs.push_back(argn->getType()); std::vector<Value*> args; args.push_back(arg1);

Hi List, My IR compiles fine and runs. I've tried to add DebugIR pass so as to be able to debug and profile it (since source is an SQL query all that I can debug and profile is IR itself). When I tried to add it to pass manager I got the following assert: Program received signal SIGABRT, Aborted. 0x00007ffff3fe4425 in __GI_raise (sig=<optimized out>) at

I just updated again (both llvm and llvm-gcc). The only thing that changed was: P test/Regression/CFrontend/2005-12-04-DeclarationLineNumbers.c The regression test below was done *with* your llvm-gcc changes to llvm- expand.c. I don't know what the failures are all about, but I will try it again. If its the same, I'll let you know. Reid. On Thu, 2006-04-13 at 16:20 -0500, Chris Lattner

Hello, I would like to see if this issue is a result of a misunderstanding on my part before I file a bug. I am using LLVM 3.4, built from the source tarballs. My system's uname is "Darwin tyler-air 12.5.0 Darwin Kernel Version 12.5.0: Sun Sep 29 13:33:47 PDT 2013; root:xnu-2050.48.12~1/RELEASE_X86_64 x86_64". All I'm trying to do is add a runtime check after all call

Hi LLVM-ers, I am trying to get a return type of a function(from bitcode file) with LLVM-C API, but there seems no appropriate API to do that. I've tried to do that with following code, ---- LLVMModuleRef M; LLVMMemoryBufferRef MemBuf; LLVMValueRef F; // Function LLVMTypeRef RetTy; char *ErrStr; // // -- Load shader module //
