[LLVMdev] Passing arguments to opt via clang

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?

Thx,
PMon
