Hello gcc developers! These patches add support for the MIPS Allegrex CPU (a device present in the Sony PSP). There's support for this CPU in binutils as of 2.41.
This CPU is mostly a MIPS II CPU with some extra instructions and a few quirks. Running the testsuite produces no regressions. I also added some test cases for the new and modified instructions.
