[Bug tree-optimization/32224] New: [4.3 Regression] ICE in vect_analyze_operations, at tree-vect-analyze.c:374

[tbm at cyrius dot com]

I'm seeing the following ICE with current trunk.  This was introduced at
some point between 20070131 (works) and 20070303 (ICE).  This is on x86_64.

(sid)25015:tbm@em64t: ~] /usr/lib/gcc-snapshot/bin/gcc -c -O -ftree-vectorize
gmp-export.c
gmp-export.c: In function 'gmpz_export':
gmp-export.c:4: internal compiler error: in vect_analyze_operations, at
tree-vect-analyze.c:374
Please submit a full bug report,

Testcase:


typedef unsigned long int *mp_ptr;
typedef const unsigned long int *mp_srcptr;
gmpz_export (void *data)
{
  mp_srcptr zp;
  int count, i;
  mp_ptr __dst = ((mp_ptr) data);
  mp_srcptr __src = (zp);

  for (i = 0; i < count; i++)
  {
    __asm__ ("bswap %q0": "=r" (*__dst):"0" (*(__src)));
    __src++;
  }
}
