I use

$ ~/gcc/bin/gcc --version
gcc (GCC) 4.3.0 20070307 (experimental)

to compile

double rdtsc_cputick;

double
rdtsc ()
{
  unsigned long eax, edx;
  asm volatile ("rdtsc" : "=a" (eax), "=d" (edx));
  return rdtsc_cputick * ((unsigned long long) edx << 32 | eax);
}

and I receive the error

$ ~/gcc/bin/gcc -c rdtsc.c -march=prescott
rdtsc.c: In function ‘rdtsc’:
rdtsc.c:9: internal compiler error: in gen_split_1956, at
config/i386/sse.md:128

After an svn update and a full bootstrap, it still breaks for me for gcc (GCC)
4.3.0 20070308, svn revision 122699.

Works for me on 4.3.2, 4.4.0 and 4.5.0. Suppose it's fixed.
