It used to work fine with the cfrontend that came together with llvm. Do you guys know what can be happening? 2) If I try: llvm-g++ source.cpp -o source ; source I get this error:...

I am getting a simular problem with ___main appearing if '@main' is used but there is no instance of it in the Module iterators, only in the relocations. Is it possible to do something about these 'ghost symbols' and have them defined in Module. Rather than having to check for them and pick them up when processing relocation...

Dear guys, my llvm-gcc does not compile stdlib.h correctly. I found this explanation here: http://llvm.cs.uiuc.edu/bugs/show_bug.cgi?id=567 Indeed, I am running Mac OS 10.4. Do I have to rebuild my gcc front-end from source, or there is a script in the LLVM website that could help me? Best regards, Fernando

Rebuilding llvm-gcc4 from source should work fine. Please see the directions in the file README.LLVM at the top level src directory. You can check llvm-gcc4 out from Subversion with the command: svn co svn://anonsvn.opensource.apple.com/svn/llvm/trunk llvm-gcc4 Reid.

Hi @ll, compiler-rt implements (for example) the MSVC (really Windows) specific routines compiler-rt/lib/builtins/i386/chkstk.S and compiler-rt/lib/builtins/x86_64/chkstk.S as __chkstk_ms() See <http://msdn.microsoft.com/en-us/library/ms648426.aspx> Is there any special reason why compiler-rt doesn't implement other MSVC specific functions (alias builtins or "compiler
