Predefined preprocessor macros

GCC defines the following preprocessor macros for the IDT/MIPS configurations:

Any MIPS architecture:

mips, _mips, __mips__, ___mips__, __mips, ___mips.

MIPS architecture with big-endian numeric representation:

MIPSEB, _MIPSEB, __MIPSEB__, ___MIPSEB__, __MIPSEB, ___MIPSEB.

MIPS architecture with little-endian numeric representation:

MIPSEL, _MIPSEL, __MIPSEL__, ___MIPSEL__, __MIPSEL, ___MIPSEL.

r3000 MIPS processor:

R3000, _R3000, __R3000__, ___R3000__, __R3000, ___R3000.
