It appears that gcc is better at optimising a double call to min and max
rather than open coded min3 and max3. This can be observed here:
$ cat min-max.c
#define min(x, y) ({ \
typeof(x) _min1 = (x); \
typeof(y) _min2 = (y); \
(void) (&_min1 == &_min2); \
_min1 < _min2 ? _min1 : _min2; })
#define min3(x, y, z) ({ \
typeof(x) _min1 = (x); \
typeof(y) _min2 = (y); \
typeof(z) _min3 = (z); \
(void) (&_min1 == &_min2); \
(void) (&_min1 == &_min3); \
_min1 < _min2 ? (_min1 < _min3 ? _min1 : _min3) : \
(_min2 < _min3 ? _min2 : _min3); })
int fmin3(int x, int y, int z) { return min3(x, y, z); }
int fmin2(int x, int y, int z) { return min(min(x, y), z); }
$ gcc -O2 -o min-max.s -S min-max.c; cat min-max.s

fmin3 function, which uses open-coded min3 macro, is compiled into total
of ten instructions including a conditional branch, whereas fmin2
function, which uses two calls to min2 macro, is compiled into six
instructions with no branches.
Similarly, open-coded clamp produces the same code as clamp using min and
max macros, but the latter is much shorter:
$ cat clamp.c
#define clamp(val, min, max) ({ \
typeof(val) __val = (val); \
typeof(min) __min = (min); \
typeof(max) __max = (max); \
(void) (&__val == &__min); \
(void) (&__val == &__max); \
__val = __val < __min ? __min: __val; \
__val > __max ? __max: __val; })
#define min(x, y) ({ \
typeof(x) _min1 = (x); \
typeof(y) _min2 = (y); \
(void) (&_min1 == &_min2); \
_min1 < _min2 ? _min1 : _min2; })
#define max(x, y) ({ \
typeof(x) _max1 = (x); \
typeof(y) _max2 = (y); \
(void) (&_max1 == &_max2); \
_max1 > _max2 ? _max1 : _max2; })
int fclamp(int v, int min, int max) { return clamp(v, min, max); }
int fclampmm(int v, int min, int max) { return min(max(v, min), max); }

48 bytes reduction. The do_fault_around was a few instruction shorter
and as far as I can tell saved 12 bytes on the stack, i.e.:
$ grep -e rsp -e pop -e push do_fault_around.*

There are also fewer branches:
