[llvm-dev] Source to Source compiler to implement "#pragma forceinline [recursive]" using clang

I would like to see the effects of inlining C/C++ functions at the source
code level.
After some searchs it looks like IDEs like Eclipse can do that on Java
code, but not in C/C++. Am I right?

Also I would like to control when to inline or not inline a function at the
calling site. I understand that Intel's ICC "#pragma forceinline" is
exactly addressing this, in contrast to the GCC
"__attribute__((always_inline))" which is addressing all the function

I understand that it would be possible to implement such translation using
clang. Do you foresee any major roadblock for that?
I am also wondering if anyone has done anything similar, or there exist
other alternatives I haven't though of...
