Hi Sachin,
Kindly tell me if a MachineFunctionPass runs only on some selected portions of the .text section. Is there a way to make it run on larger portion of the .text section?
Your pass should have access to the vast majority of what LLVM puts in the text section: every function compiled by LLVM. The linker may put more things in there (either entire libraries if you're linking statically, or possibly stubs otherwise).
I'm afraid it's impossible to say exactly what's going on in your case without more details of what you're seeing and why that differs from what you expect to see though.
Cheers.
Tim.
