it only works in the initializer and not as a statement after the fact.
That is:
#include <assert.h>
int foo (int x)
{
int y = y;
assert (x == 0 || x == 1);
if (x == 0)
y = 1;
else if (x == 1)
y = 2;
return y;
}
Will work, also with the jump threading, GCC should be able to figure out that
y is always inlined (except when -DNDEBUG is used).
