Summary: Internal Error when the switch arg is a constant

Initial Comment:
Hi.



The following program (attached), compilled with the

newest sdcc from CVS, gives an Internal Error message.



$ sdcc -mmcs51 --nojtbound int_err.c

Internal error: validateOpType failed in

OP_USES(IC_JTCOND (ic)) @ SDCCcse.c:1740: expected

symbol, got value



Program:

---

int main()

{

  switch (2) {

    case 3: return 3;

    case 2: return 2;

    case 1: return 1;

  }

  return 0;

}

---



This is a just another "educational" bug, i.e. the

severity is nearly zero, but is probably worth fixing

anyway:)

Completed fix in src/SDCCicode.c 1.168



("Initializer element is not constant" was a result of

attempting to use setOperandType (cond, UCHARTYPE) when cond

was literal, leaving it with a type but no value)

The internal error is fixed in SDCCcse.c 1.84. But there are 

still 2 errors "Initializer element is not constant".
