If it is so bad, you can avoid this opcode. Just remove this code from
lcode.c:
case OP_RETURN: {
if (GET_OPCODE(i) == OP_CALL && GETARG_B(i) == MULT_RET) {
SET_OPCODE(i, OP_TAILCALL);
SETARG_B(i, arg1);
optm = 1;
}
break;
}
That way, the compiler will not do the optimization; it will keep an
explicit OP_CALL followed by OP_RETURN in your code.
