// C testcase, use '-O1 -mregparm=1 -fschedule-insns -march=i386':

struct A
{
  int j;
};

void foo (struct A *p, int j)
{
  p->j = j % 3;
}

	* reload.h (struct insn_chain): Add need_operand_change element.
	* reload1.c (new_insn_chain): Clear it.
	(calculate_needs_all_insns): Set it; don't overload need_reload.
	(reload_as_needed): Use it.
