Thanks, but I'm not sure I understand. I see no such flag in clang 2.9 nor couldn't I find any mention of it. What does it do?

What does it do?I think he meant -mllvm not -mlvm. The next thing that follows is passed to LLVM, for example -mllvm -disable-llvm-optzns Ciao, Duncan.> > > Harel Cain > > > On Sun, Mar 4, 2012 at 15:03, Anton Korobeynikov <anton at korobeynikov.info > <mailto:anton at korobeynikov.info>> wrote: > > > In the good old llvmc, the -Wo flag could be used to pass arguments to the > > optimizer.

I have tried to invoke a transformation/optimization pass using -mllvm, without success. I might be missing something. For example I have a shared/dynamic library which contains LLVM passes. I used to invoke them with llvmc like this:>>*llvmc mycode.c -o mycode.o -c -opt -Wo,=-load,libFoo.dylib,-Foo*Can this style of optimization be executed using -mllvm argument?
