llvm dev - Jun 2013 - [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

No. You cannot add additional passes this way, only pass 'ordinary'
arguments.

what is the solution to pass opt arguments , non ordinary  passes like :
*-std-link-opts* by clang ? 
Dose clang invoke opt in normal compilation procedure even?
