llvm dev - Jan 2020 - Replacing operands in a call instruction

Hello,

I am trying to replace a pointer argument of a call instruction with
another pointer argument( new argument value for the call instruction).
What is the best way to do it? I could not find any hint/guidance on the
web or LLVM manual.

Thanks,

You probably want CallBase::setArgOperand. You have to make sure the
types are the same of course, changing the type of an entity in LLVM
is substantially more involved.

Cheers.

Thanks!
