Hello !
I'm looking again on the reports done with Coverity Scan and found several
things one of it is this:
static void asm_expr_prod(TCCState *s1, ExprValue *pe)
{
int op;
ExprValue e2;
asm_expr_unary(s1, pe);
for(;;) {
op = tok;
if (op != '*' && op != '/' && op != '%' &&
op != TOK_SHL && op != TOK_SAR)
break;
next();
asm_expr_unary(s1, &e2);
if (pe->sym || e2.sym)
tcc_error("invalid operation with label");
switch(op) {
case '*':
pe->v *= e2.v;
break;
case '/':
if (e2.v == 0) {
div_error:
tcc_error("division by zero");
}
pe->v /= e2.v;
break;
case '%':
if (e2.v == 0)
goto div_error;
pe->v %= e2.v;
break;
case TOK_SHL:
pe->v <<= e2.v;
break;
default:
case TOK_SAR: ////////////////////////////////////////this case
after default what does it mean ??????????????
pe->v >>= e2.v;
break;
}
}
}
