Is MIPS ASE what you need? Standard gcc supports:

MIPS DSP ASE rev1
MIPS DSP ASE rev2
MIPS SmartMIPS ASE
MIPS Digital Media Extension
MIPS-3D ASE
(optional paired-single floating-point instructions)

If you have vendor patches for gcc-4.7 I could integrate those. But we
need either gcc 4.7 or 4.8 patches for gdc, crosstool-NG+gdc actually
only works with 4.7
