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)
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.
