[LLVMdev] Is it possible to inline Functions without using LLVM JIT Framework?

[Mian M. Hamayun]

Thanks Eric, Jim and Geovani for your responses.

Yes, we can combine two or more bitcode modules using llvm-ld and in 
this way functions can be inlined and optimized during this process.

But I am also looking into the possibility of doing the same using LLVM 
Pass Manager (Without using llvm-ld). This looks difficult due to the 
fact that the function definitions ought to be in the same module as the 
caller, in order to be inlined and then optimized onwards, I guess !!! 
(Correct me If I am Wrong at this)

Thanks Again,
Hamayun

P.S. @Geovani: "You have tried do it in semantical phase?"
Which LLVM Passes are you referring here ? Because I am working at the 
LLVM-IR Level, where I generate LLVM-IR modules, optimize them and then 
compile them for a given target.
