Here's what is actually triggering that crap. Have fun...
#define __u16 unsigned short
static inline __attribute__((__const__)) __u16 f(__u16 val)
{
return val;
}
static inline void barf(unsigned int len)
{
}
static inline unsigned int bar(__u16 n)
{
switch (n) {
case (__builtin_constant_p(1) ? 1 : f(1)):
return 4;
default:
return 0;
}
}
int foo(__u16 n)
{
unsigned int x = bar(n);
barf(bar(n));
return 0;
}
