[LLVMdev] clang and static functions

[Arvind Sudarsanam]

Hi,

Sorry for not being specific. I just wanted to know if there is any
way at all to force clang to generate intermediate code for static
functions when they are not being called anywhere inside the current
module. Other compilers seem to generate intermediate code (lcc, for
instance).

Thanks for your reply..Olivier.

Sincerely
Arvind
