This patch mixes some independent features. If I remember correctly BALIGN and BITREV have been added to the MIPSR6 ISA (and microMIPSR6) and were previously only in DSPR2. The BPOSGE32C instruction is part of DSPR3 and is the only new instruction in DSPR3 with BPOSGE32 being removed from microMIPS DSPR3 but retained in MIPS DSPR3. The CMP* are pre-existing DSPR2 (or may even be DSPR1 I do not know from memory).
