--- Comment #1 from Tom de Vries <vries at gcc dot gnu.org> ---
Looking at insn-emit.c, we see:
...
/* src/gcc/config/sh/sh.md:2273 */
rtx
gen_udivsi3 (rtx operand0,
rtx operand1,
rtx operand2)
{
rtx_insn *_val = 0;
start_sequence ();
{
rtx operands[3];
operands[0] = operand0;
operands[1] = operand1;
operands[2] = operand2;
#define FAIL return (end_sequence (), _val)
#define DONE return (_val = get_insns (),end_sequence (), _val)
// #line 2278 "src/gcc/config/sh/sh.md"
{
rtx last;
operands[3] = gen_reg_rtx (Pmode);
...
In other words, we declare an array with size 3: "rtx operands[3]", and then
write the 4th element: "operands[3] = gen_reg_rtx (Pmode)".
