[LLVMdev] a strange emit of llvm-g++

[Seung Jae Lee]

I tested a simple function shown as follows for for llvm-g++:
-------------------------------------------------------------
void f_loop(long* c, long sz) {

   long i;
   for (i = 0; i < sz; i++) {
      long offset = i * sz;
      long* out = c + offset;
      out[i] = 0;
   }
}
-------------------------------------------------------------

LLVM assembly was emitted out as follows:
-------------------------------------------------------------
void %_Z6f_loopPll(int* %c, int %sz) {
entry:
        %sz = cast int %sz to uint              ; <uint> [#uses=1]
        %tmp18 = setgt int %sz, 0               ; <bool> [#uses=1]
...
...
...
-------------------------------------------------------------
The function name is strange.. Hmmm...

llvm-gcc emitted normally as shown like this:
-------------------------------------------------------------
void %f_loop(int* %c, int %sz) {
entry:
        %sz = cast int %sz to uint              ; <uint> [#uses=1]
        %tmp18 = setgt int %sz, 0               ; <bool> [#uses=1]
...
...
...
-------------------------------------------------------------
Is this a bug?
(?_?)
