GCC 4.7 has very similar atomic built-ins: <https://gcc.gnu.org/onlinedocs/gcc-4.7.4/gcc/_005f_005fatomic-Builtins.html#g_t_005f_005fatomic-Builtins> But the previous built-ins go *way* back: <https://gcc.gnu.org/onlinedocs/gcc-4.1.2/gcc/Atomic-Builtins.html> The question is whether the relevant MIPS variants have proper support. I don't know the answer.
