Hmm... you mean changing this
#define grub_swap_bytes16(x) \
({ \
grub_uint16_t _x = (x); \
(grub_uint16_t) ((_x << 8) | (_x >> 8)); \
})
...for this
inline grub_uint16_t grub_swap_bytes16(uint16_t x)
{
return (x << 8) | (x >> 8);
}
and such? The pro is that we get rid of the ugly hack in the macro
version that ensures single evaluation, but a con is that we cannot
_force_ any random compiler to inline anything, so we might end up with
gross numbers of function calls.
By the way, what is "sparse annotate"?
