llvm dev - Apr 2012 - [LLVMdev] Determing C Types

What is the best way to determine the type of an arbitrary int? For
example, find whether it is a char, short, int, long, long, etc?

So what I would like to do is redefine the widths for the types, making the
type widths more portable and less target dependent, is this possible
within llvm?

If what you're trying to do is use LLVM as a target-independent bitcode
representation, you should be aware that it's not made for that purpose. In
fact, it's specifically *not* target-independent, no matter what the types
are.

For you initial question, you cannot map back from LLVM IR to C types, because
the two have little to do with each other.
