Hi, the following testcase (extracted from Mesa sources) fails to compile on
current 3.3-hammer and 3.4 (20030723) with "-O -march=pentium3 -mfpmath=sse".
This is a regression from plain 3.3-branch.

/* { dg-do compile { target i?86-*-* } } */
/* { dg-options "-O -march=pentium3 -mfpmath=sse" } */

static void f ()
{
  unsigned ui[2];
  int i;
  i = (float)ui[0];
}

[gb@hp6 gcc]$ ./cc1 --version
GNU C version 3.4 20030723 (experimental) (i686-pc-linux-gnu)

[gb@hp6 gcc]$ ./cc1 -O -march=pentium3 -mfpmath=sse ~/vrac/i386-ssefp-3.c
 f
/home/gb/vrac/i386-ssefp-3.c: In function `f':
