[ Reported to the Debian BTS as report #166940.

Trying to compile the following code:

// mmxtest.c
typedef int v4hi __attribute__ ((mode(V4HI)));
int main(int argc,char *argv[])
{
  v4hi a;
  v4hi result =  __builtin_ia32_psraw(a,1);
}

with: gcc-3.2 -mmmx -c mmxtest.c
and got the following error:
mmxtest.c: In function `main':
mmxtest.c:6: Internal compiler error in ix86_expand_binop_builtin, at
config/i386/i386.c:11503
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.

I am getting the same error with psllw and psrlw, I have not tested
others.
