Hello I'm trying to install LLVM and LLVM GCC so I check out the source of llvm and llvm-gcc-4.2 from the svn I flow the instructions of this page http://llvm.org/docs/GCCFEBuildInstrs.html I did the installation of LLVM and LLVM GCC well but the problem is there is no llvm-gcc at the end of instalation !!! ?? I mean in the /usr/local/bin/ there are all the commands of llvm (lli llc llvmc

You need to manually copy the llvm-gcc front-end binaries to somewhere in your path. Alternatively, you can download the clang front-end and start using that instead.

Hello I'm wandring to know how many times a block is executed inside a loop ? knowing that I can't use getSmallConstantTripCount() because the number is unkown "for (i=0;i<N;i++) for example" I'm using a Function pass for (Function::iterator BB = F.begin(), E = F.end(); BB != E; ++BB) { if (Loop *L = LI->getLoopFor(BB)) { if (L->getHeader() ==

Dear all, I want to build an LLVM pass by using CMake. After reading the ralevant part of the documentation ( http://llvm.org/releases/3.1/docs/CMake.html#passdev), I copied the files in the llvm/lib/Transforms/Hello to another folder in order to give a try. Then I renamed the folder as Hello2. Then I have changed CMakeLists.txt as following: cmake_minimum_required(VERSION 2.8) # A

Hello I'm wandring to write a Function parser that iterates over loops inside each function and inside each loop iterates over instructions So I found a way to do the Function parser that iterates over BasicBlocks (using the runOnfunction Pass) but I no know how make it iterates over loops ? So my question is there any way to make a loop inside the runOnfunction to iterate over

Hello How to get the type of an Operand ? so for example I want to get the type of the operand(0) in this istruction %arrayidx22 = getelementptr [1000 x double]* %C, i64 0, i64 %indvar67 ; <double*> [#uses=1] I tried (II->getOperand(0))->getType() ) but this give me an adress (I think) (some think like 0x1253.. ) also I tried to get the type of the instruction with switch

For example: int main(char **argv, int N) { for

Hi，All this one pass that will use the Linker namespace { // Hello2 - The second implementation with getAnalysisUsage implemented. llvm::StringRef programNametest(""); struct Hello2 : public ModulePass { static char ID; // Pass identification, replacement for typeid Hello2() : ModulePass(ID) {} virtual bool runOnModule(llvm::Module &M){ llvm::Linker

Hi I create a simple bytecode file with clang -c -emit-llvm test.c -o test.bc #include <stdio.h> void hello(){ printf("hello\n"); } void hello2(){ printf("hello2\n"); } Then i want to keep only the hello function so i do : llvm-extract -func=hello -o test2.bc test.bc but the string constants are removed and "@.str" is marked as external @str

Hi, I have a very naive question. I've written a pass that gets an argument from the command line with the following code: static cl::opt<int> LineNum("line-number", cl::Hidden, cl::Required,cl::desc("line of variable being observed")); Now when I run it, it seems like it cant see that I've put in an argument on the command line: opt -load

I''d been trying to iterate through an array of hashes using the ActionController''s render method. Unfortunately, it appears that when I use a hash as one of the array elements, it gets passed as a nil to the partial. Here''s some code: @books = [ ''hello'', ''hello2'' ] render :partial => "book",

Hi LLVM developers, $ cat hello.c #include <stdio.h> void foo() { } int main(int argc, char *argv[]) {   for (int i = 0; i < 10; i++) {     printf("%d\n", i);   }   return 0; } $ /opt/llvm-svn/bin/clang --version Fedora clang version 6.0.0 (trunk 316308) (based on LLVM 6.0.0svn) Target: x86_64-redhat-linux Thread model: posix InstalledDir: /opt/llvm-svn/bin $

Hi Hal, Thanks for your hint! $ /opt/llvm-svn/bin/opt -S -internalize -internalize-public-api-list=main -globaldce hello3.ll -o hello3.dce.ll    it works :) But I argue that `main` Function should be inserted into ExternalNames by default: Index: lib/Transforms/IPO/Internalize.cpp =================================================================== --- lib/Transforms/IPO/Internalize.cpp 

I want to use PgmDependenceGraph pass , but my pass cannot work with PgmDependenceGraph. I tried again in Hello2 pass, and it could not work also. The following is I did with llvm/lib/Transforms/Hello.cpp: 1.insert #include "llvm/Analysis/PgmDependenceGraph.h" in Hello.cpp. 2.insert AU.addRequired<PgmDependenceGraph>() in the getAnalysisUsage(AnalysisUsage &AU) of Hello2.

Have you tried to pass --enable-shared to configure? It works for me. $ opt -load /usr/local/lib/LLVMHello.dylib -help | grep hello -hello - Hello World Pass -hello2 - Hello World Pass (with getAnalysisUsage implemented) - xi On Aug 21, 2012, at 5:55 PM, Ashwin kumar <ashwinkumar18 at gmail.com> wrote: >

Hi all, I was trying to set up an interface for using C functions in R. For this, my R file hello2.r is: --------------------------------------------------------------------------------- hello2 <- function(n) { .C("hello", as.integer(n)) } hello2(3) -------------------------------------------------------------------------------- and my hello.c file is:
