Hello; I wanted to insert two new terminator instructions in LLVM IR. I modified the necessary files (as mentioned in the tutorial in LLVM site and some more to meet the new structure of LLVM, (e.g no Lexer.l now, we have LLLexer.cpp. Again in the tutorial, files like LLVMBitCodes.h, include/llvm-c/core.h that need to be modified are not mentioned) But I am getting the error while building

Hey guys, I have seen your interesting conversion. I am new for LLVM as well as clang compiler. I am going to use it now. it is quite difficult when someone starts it from scratch. But it is enjoyable and it is possible to familiarize with the environment by short time. Am gonna to use clang + llvm to generate AST from source code by using clang and to do high level transformation. Then I want to

Hello, What you're describing is basically the parsing and codegen portions of clang. I'd suggest reading through the code there and posting to clang-dev if you have any specific questions. The clang devs are more likely to see your questions there as not all of them also hang out here. Regards, Jim On Sep 28, 2011, at 8:28 PM, eyasu getahun <eya.get at gmail.com> wrote: >

I just read that LLVM project could be used to do static analysis on C/C++ codes using the analyzer Clang which the front end of LLVM. I wanted to know if it is possible to extract all the accesses to memory(variables, local as well as global) in the source code using LLVM. Is there any inbuilt library present in LLVM which I could use to extract this information. If not please suggest me how to

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

Hey Xiaoming, Thanks for those source codes. Can you please explain what this llvm-memory-profiling.patch does ?

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

Hey John, Thank you for the detailed reply. I tried to figure out myself which IR should I use for my purpose ( Clang's Abstract Syntax Tree (AST) or LLVM's SSA Intermediate Representation (IR). ), but couldn't really figure out which one to use. Here is what I m trying to do. Given any C/C++ program (like the one given below), I am trying to insert calls to some function, before and

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

Branches have been created. You are free to checkin to cvs head again. I'll send mail once I have the prerelease tar balls up. Please continue to review and revise the documentation. I can fold this into the release later. Thanks, Tanya On Thu, 13 Apr 2006, Tanya Lattner wrote: > > I will be creating the release branch at 1:00pm PDT. Please refrain from > checking in from

I will be creating the release branch at 1:00pm PDT. Please refrain from checking in from 1:00-1:30pm. I will send email once I am done. Thanks, Tanya

Here's what's left on Linux (GCC 4.1.0), after all updates that went into the branch: Running /proj/llvm/build/../llvm/test/Regression/CFrontend/dg.exp ...

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 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

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) {

Hi, this looks very promising. Do you have any plans to add bindings for the use of an ExecutionEngine, especially recompileAndRelinkFunction? I've build an interactive toplevel implemented in OCaml and I have to pull of some stunts to be able to change the definition of a function. (emit a .ll file containing the code, looking up the function and calling removeBody, then reading
