Here is the reduced testcase:
typedef unsigned long long HARD_REG_ELT_TYPE;
typedef HARD_REG_ELT_TYPE HARD_REG_SET[2];
static HARD_REG_SET newpat_used_regs;
int try_combine (void)
{
 HARD_REG_ELT_TYPE *scan_tp_ = newpat_used_regs;
 scan_tp_[0] = 0;
 scan_tp_[1] = 0;
}
: Search converges between 2004-07-27-trunk (#496) and 2004-07-28-trunk (#497).
