Hi, I wish to implement dead code elimination as a pass in llvm. This is not the same as unreachable block. For this, I plan to go ahead like this : In each function Identify the store and branch operations Identify the operands involved in these operations. Build the UD chain of these and check if there is any variable that is not used and mark its definition (the entire instruction)

I used successors to find the basic blocks that can be visited and those that cannot be reached. My pass just prints out those blocks which can be reached. The problem is that I want to include this in my compiler code rather than as a separate .cpp file which will perform the pass when I use 'opt'. I have seen that there is something called a PassManager class. Will this help me any way ?

Hi, I am a new user of LLVM. I am using it as the IR for a compiler for a subset of LUA. I have the .ll file ready and it executes fine when passed to the llvm interpreter. Now, I wish to perform a few optimizations to the code starting with dead code elimination. For this I would need the CFG. I am very new to all of this stuff. Please help me out guys. The way I want to proceed is to start at

I need to add, also you'll need bison+flex.

Thanks. It worked for a few more compilation lines. I now get the following linker error: undefined reference to llvm::MemoryBuffer::getNewMemBuffer(unsigned long, llvm::StringRef) I am surprised since the linker compile line already links with a whole bunch of llvm libraries ...

I got this one fixed by rebuilding llvm Debug (oups). I had an old version. I now seem to have a classical message: version GLIBCXX_3.4.14 not found. I am indeed building llvm-gcc using gcc4.5.

Ok. Thank you for your input. New questions :) : - Is the dev package basically the source code of gcc 4.2 ? Isn't it already fully included in llvm-gcc code base ? - How should I include bison+flex when I have installed Do I need to put additional flags to configure script ?

hi, I am getting following compilation error while compiling llvm. I installed the missing libs. using my package manager (and there are in /usr/loca/lib path). Any clue to fix the problem.

Hi, I have been using VNC on CentOS 7 server from last couple of months and it was running all fine till last night. Unfortunately, there was an abrupt power failure and system got restarted. Now, when I try to login with VNCviwer, it thrown an error message- "*Gnome - oh no! Something has gone wrong "* with a logout option. When I click on logout, I see black/dark gray screen with 3

You'll need to install the dev packages for gcc 4.2.

Hello all, I am trying to build the latest version of llvm-gcc on a x86_64 architecture running a Linux distribution. Using the READM.LLVM I have managed to run ./configure using appropriate options, but when I try to build using make, it shows the following error message after a few seconds: ../../llvm-gcc/gcc/gengtype-lex.l:31:27: fatal error: gengtype-yacc.h: No such file or directory.

Hi All, The other thing we have noticed after booting is, screen is completely blank. GUI is not visible on attached monitor. We tried switching between different terminals using (Ctl+Alt+F1-12). F2-6 are showing command line terminals but, others are returning blank screen only. It appears that, there is some problem with GUI/gnome. Is there any way to fix this? Please help. Regards Hersh On

There were no live connections. The problem what we had was more related to OS requirement for some software. This drive was not in a bad shape.

Hi All We want to install packages like xfig and transfig on centos 5.5. We found rpms available but them but it seems there are lot of dependencies for these packages. So we would like to setup yum repo for this. Can anyone suggest trusted baseurl for yum repo? Regards Hersh -------------- next part -------------- An HTML attachment was scrubbed... URL:

Puyan, There is a doc on the document page which describe the list of broken GCCs. You'll need to check it once the docs are online.

Hi Does there exist a list of relative compile times for source files in LLVM? I am doing a build for ARM on an actual ARM device, and CodeGenDAGPatterns.cpp is taking a really long time to compile (it's been like 20 minutes or more). I don't even get an error. All the files before it compile pretty quickly but this file in particular just won't finish. The version of gcc I have on
