Reduced down to:
void bar (unsigned int);
void
foo (void)
{
char buf[1] = { 3 };
const char *p = buf;
const char **q = &p;
unsigned int ch;
switch (**q)
{
case 1: ch = 5; break;
case 2: ch = 4; break;
case 3: ch = 3; break;
case 4: ch = 2; break;
case 5: ch = 1; break;
default: ch = 0; break;
}
bar (ch);
}
This is one of those rare cases where CSE1 folds a switch statement.
