Hi, This patchset aims to cleanup the MIPS optimizations a bit and add support for 64-bit processors.
I haven't attempted specifically to optimize any of this for 64-bit systems, except for the removal of some assembly blocks which GCC can optimize just as well itself. Also I havn't gone through and cleaned up everything, just the bits that make it easier to port to 64-bits or some things that were really bugging me :) I've run fate on both 32 and 64-bit mips machines and it passes all the tests on both. I don't have a machine with DSP instructions but I managed (with some effort) to run fate using qemu and it passed all the tests there as well. One thing I was sligly uneasy about in the change I made to the configure script was forcing specific ISA levels unless you pass --disable-xxx to configure. This has a habit of causing the final binaries not to run at all (eg I have to disable DSP otherwise I get a lot of SIGILL). Since this was what the code was doing before, I just left it instead of messing up all the MIPS configure options (more than I have done).
