llvm dev - May 2010 - [LLVMdev] determining if the signness of a integer pointer

Is there a way to determine via API calls whether a pointer to an int points to
a signed integer or an unsigned integer?

Thanks,
Micah

Since LLVM doesn't have signed or unsigned integer types, I'm not sure
what you're asking.   I suppose you could look for additions done with
values loaded from or stored to the pointer...

Since the frontend knows that a int pointer is signed or unsigned, I was hoping
that this bit was set somewhere in a header file that I couldn't find when
it was creating the LLVM integer.
