Here is the code. I am running on llvm 3.1 on Lion (Mac 10.7.4)
*string getFileDirectory*(*const* Instruction &I){
MDNode *MD = I.getMetadata("dbg");
DICompileUnit compileUnit(MD);
return compileUnit.getDirectory().str();
}

I used DILocation instead of DICompileUnit and it works. Hmmm, interesting. George On Thu, Oct 4, 2012 at 1:33 AM, George Baah <georgebaah at gmail.com> wrote:> Here is the code.
