[LLVMdev] problem compiling x86 intrinsic function

[fima rabin]

I am trying to compile this little C-program:
=================
typedef double        v2f64 __attribute__((ext_vector_type(2)));

   int sse2_cmp_sd(v2f64, v2f64, char ) asm("llvm.x86.sse2.cmp.sd");

int main()
{

  static int i;
  static float x[10];
  static float y[10];
  v2f64 m1;
  v2f64 m2;

  int j;
 
    i = sse2_cmp_sd(m1,m2,'z');
==========================
I expected to see inline code for one of the X86 intrinsic functions. However, when I looked
at the *.ll file I see this function declared as

declare i32 @"\01llvm.x86.sse2.cmp.sd"(<2 x double>, <2 x double>, i8 signext)


with extra "01" character in front of the name. Subsequently this function does not match the intrinsic function
name and the resulting code produces a call to "llvm.x86.sse2.cmp.sd" function instead of inline code.

Is my C-program incorrect?

Thanks.
