https://www.linux.com – While born originally at Google as projects for LLVM, AddressSanitizer and ThreadSanitizer have been ported to GCC and will be part of the forthcoming GCC 4.8 compiler release. Back at Google, they're onto developing MemorySanitizer for LLVM. AddressSanitizer (ASAN) was developed at Google to be a fast memory error detector.

Hi,

I want to do some experiments with buffer overflows on my various virtual machines, including (but not limited to) Debian 6, Ubuntu 12.04, Fedora 16, but every time I try to execute the buffer overflow exploit I get the following message:

stack smashing detected (core dumped)

After doing my research I read that it is a feature called buffer overflow protection implemented in the compiler.

So I was surfing the net and stumbled upon this article. It basically states that FreeBSD, starting from Version 10 and above will deprecate GCC in favor of Clang/LLVM.

With LLVM/Clang 3.1 due out next week, here's a look at the compiler performance of the GCC 4.6 and 4.7 compilers compared to LLVM-Clang 3.0 and a recent LLVM-Clang 3.1 SVN snapshot...

Hi,recently i created the aur package llvm-amdgpu-svn and am now looking into adding the svn clang, clang-analyzer and llvm-ocaml code also.Since compiling clang requires the llvm source code to be present, it makes sense to use  a split package for this, like the official llvm package.This page has the build instructions for clang  : http://clang.llvm.org/get_started.htmlIn short i need

I'm writing an LLVM pass which works on the LLVM IR code. A part of the objective is to read the initial values of global variables, where global variables could be of any type, from basic types to structs and classes. How do I achieve that?
