It was:
(define_insn "movdi"
[(set (match_operand:DI 0 "nonimmediate_operand" "")
(match_operand:DI 1 "general_operand" ""))]
""
"#")
(define_split
[(set (match_operand:DI 0 "nonimmediate_operand" "")
(match_operand:DI 1 "general_operand" ""))]
"reload_completed"
[(set (match_dup 2) (match_dup 4))
(set (match_dup 3) (match_dup 5))]
"{
operands[2] = simplify_gen_subreg (SImode, operands[0], DImode, 0);
operands[3] = simplify_gen_subreg (SImode, operands[0], DImode, 4);
operands[4] = simplify_gen_subreg (SImode, operands[1], DImode, 0);
operands[5] = simplify_gen_subreg (SImode, operands[1], DImode, 4);
}")
Alas, this elementary addition has appeared erroneous.
The following program leads to emergency end of compilation:
int main ()
{
volatile long long x = 0x0102030405060708LL;
if (x != 0x0102030405060708LL)
exit (__LINE__);
exit (0);
}
