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

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

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.

1. You should run the passes in the same opt command, for passes like loops which is an analysis pass provides results to the following passes. 2. You can pass a -debug flag to opt to see the some debugging info. 3. I tried this opt -mem2reg -loops -loopsimplify -loop-unroll -unroll-count=3 -debug loop.o -o tt.bc and got this message. Loop Size = 14 Can't unroll; loop not terminated by

Hello, I started using R a month ago - so I am a novice in this area. I am stuck with a problem and need some help urgently. I am using windows version of R 1.9.1. I am trying to compile C code in it. I have my C code - "hello.c" is lying in C:\Program Files\R\rw1091 This code is - #include <R.h> void hello(int *n) { int i; for(i=0;i< *n; i++) {

Hello is there any way to pass argument to my own Function pass I mean I wrote a Function pass (like Hello) that give me somme analyzes about the code source and I need to pass somme argument to the Pass like the size of data.... I want some think like this opt -load ../../../Debug/lib/LLVMHello.so -hello2 < test.bc > /dev/null arg1 arg2 ... So how to get inside the Function pass the

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

Thank you very much! To make it simpler, I may as well just implement the self-written "check function" in C language instead of wrapping it in LLVM module. According to the hint you give me, all I need to do is as follow(?) 1. Implement the "Check function" in the check.c file; 2. Add the check function into the module(the Hello1.bc file which I will run the functionPass on)

That sounds like a good general plan, yes!

Hello Folks It's with some trepidation that I venture on to such a heady newsgroup, but I'm about ready to throw myself off a bridge after getting this all set up and apparently working only to be struck down by permissions and selinux hell (either, or both). I've followed instructions here: http://wiki.qemu.org/Documentation/9psetup

Hello all, Is it well known that building LLVM with --enable-optimized causes RegisterPass calls to be removed from dynamically loadable libraries (i.e., those built with LOADABLE_MODULE=1)? For example, here's what happens to the Hello pass (ToT on Darwin, both with and without --enable-optimized): $ pwd /Users/ransford/llvm/lib/Transforms/Hello $ nm -j Release+Asserts/Hello.o | c++filt -p
