           Summary: llvm-gcc4: bool on darwin turns into uint for function
                    args/results
           Product: tools
           Version: 1.7
          Platform: Macintosh
        OS/Version: MacOS X
            Status: NEW
          Severity: normal
          Priority: P2
         Component: llvm-gcc
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: sabre at nondot.org


This:

_Bool test() {}

Compiled on PPC32:

$ llvm-gcc bool.c -S -o - -emit-llvm -O3
...
uint %test() {
entry:
        ret uint undef
}


llvm-gcc represents C99/C++ bool as LLVM 'uint', because that's its proper size in memory, but 
function args/results should really really use llvm bool.  :)
