[LLVMdev] 32 bit boolean results

I am still trying to figure out why my comparison instructions are being
modified and overall producing incorrect results.


The IR produces correct results, but my backend does not and the only
thing I can think of is that the IR is treating the Booleans as i1 and
therefore either and'ing or xor'ing the results of my comparison with
the value 1.

Is there a way to tell LLVM to treat Boolean results as 32bit values
instead of 1 bit values?


LLVM IR doesn't have a concept of C level booleans.  What problem are
you trying to solve?
