------- Comment #3 from pinskia at gcc dot gnu dot org  2007-04-15 00:56 -------
Confirmed, reduced testcase:
static const __attribute__((altivec(vector__))) unsigned char array[16];
static __attribute__((altivec(vector__))) unsigned char
f1(__attribute__((altivec(vector__))) unsigned char in)
{
 __attribute__((altivec(vector__))) unsigned char v1, v2, v3, v4, v5, v6, v7,
v8;
 __attribute__((altivec(vector__))) unsigned char v0, v9, v10, v12, v13, v14,
v15;
 __attribute__((altivec(vector__))) unsigned char v16, v17, v20, v18, v19;
 v3 = __builtin_vec_perm(array[4], array[5], in);
 v4 = __builtin_vec_perm(array[6], array[7], in);
 v5 = __builtin_vec_perm(array[8], array[9], in);
 v6 = __builtin_vec_perm(array[10], array[11], in);
 v7 = __builtin_vec_perm(array[12], array[13], in);
 v8 = __builtin_vec_perm(array[14], array[15], in);
 v13 = __builtin_vec_sel(v3, v4, v0);
 v14 = __builtin_vec_sel(v5, v6, v0);
 v15 = __builtin_vec_sel(v7, v8, v0);
 v19 = __builtin_vec_vslb(in, ((__attribute__((altivec(vector__))) unsigned
char) __builtin_altivec_vspltisb (((1)))));
 v9 = (__attribute__((altivec(vector__))) unsigned
char)__builtin_vec_vcmpgtub(v19, array[2]);
 v16 = __builtin_vec_sel(v12, v13, v9);
 v17 = __builtin_vec_sel(v14, v15, v9);
 v20 = __builtin_vec_sel(v16, v17, v10);
 return v20;
}
int f2(__attribute__((altivec(vector__))) unsigned char av[15])
{
 unsigned __attribute__((altivec(vector__))) char tmp;
 unsigned int i;
 for (i=0; i< 20; i++)
  {
  tmp = f1(tmp);
  av[i] = tmp;
