Reid, Thank you for your quick reply. Yes, I have built and installed llvm-gcc and "llvm-gcc --print-prog- name=cc1" return the correct path for cc1, so I assume its path is set correctly in the config files, but I haven't installed config files separately. Do I need to do that? Is there any documentation about it?

Thank you Chris. Actually, I have changed the stack organization in the "llc" source codes for x86 target. Thus, I need libraries compiled with the new stack organization. If I use llvm-gcc (and apparently also llvmc), llc will not be invoked. I was hoping that llvmc would call llvm-gcc to compile to bc file and then call llc to compile to native assembly, but apparently this doesn't happen. Do you know of any possible ways to involve llc in compilation of libraries? --Babak On May 8, 2007, at 11:33 PM, Chris Lattner wrote:> On Tue, 8 May 2007, Babak Salamat wrote: >> Yes, I have built and installed llvm-gcc and "llvm-gcc --print-prog- >> name=cc1" return the correct path for cc1, so I assume its path is >> set correctly in the config files, but I haven't installed config >> files separately.
