--- Comment #2 from Jonathan Gray <j...@openbsd.org> ---
It seems mips64 got the sync builtins later than other platforms, they are
available in later versions of gcc but not gcc 4.2.
Alpha also hit an ICE so for now we stopped building Mesa on alpha/mips64 in
OpenBSD.
lib/mesa/src/mesa/main/format_pack.c -fPIC -DPIC -o main/.libs/format_pack.o
/usr/xenocara/lib/mesa/src/mesa/main/format_pack.c: In function
'pack_float_bgr_srgb8':
/usr/xenocara/lib/mesa/src/mesa/main/format_pack.c:6890: error: unrecognizable
insn:

For other architectures we currently build with:
#elif defined(__ARM_ARCH_4__) || defined(__ARM_ARCH_5__) || \
defined(__hppa__) || defined(__sparc__) || defined(__sh__)
#define PIPE_ATOMIC_UNLOCKED
...
#if defined(PIPE_ATOMIC_UNLOCKED)
#define PIPE_ATOMIC "Unlocked"
#define p_atomic_set(_v, _i) (*(_v) = (_i))
#define p_atomic_read(_v) (*(_v))
#define p_atomic_dec_zero(_v) ((*(_v) -= 1) == 0)
#define p_atomic_inc(_v) (*(_v) += 1)
#define p_atomic_dec(_v) (*(_v) -= 1)
#define p_atomic_add(_v, _i) (*(_v) += (_i))
#define p_atomic_inc_return(_v) (*(_v) += 1)
#define p_atomic_dec_return(_v) (*(_v) -= 1)
#define p_atomic_cmpxchg(_v, old, _new) ({ \
__typeof(*_v) _r = *(_v); \
if (*(_v) == old) \
*(_v) = (_new); \
_r; \
})
