Missed a few extra details... DSPR3 requires a minimum of MIPSR6/microMIPSR6 and DSPR1/2 is allowed with MIPSR6 but not allowed with microMIPSR6. The DSP ASE also has flags to set in the .MIPS.abiflags section if this is not already implemented. These details are partly important for correctness and partly for accurate tracking of object content. These need not be dealt with in this patch, just extra things to handle.
