James CowgillandMichael Niedermayer a251aa1a35 mips/asmdefs: use _ABI64 as defined by gcc
Unfortunately android < api 21 (lollipop) doesn't have the sgidefs.h header,
the easiest way around this is to just use the preprocessor definitions from
gcc / clang.

James CowgillandMichael Niedermayer 157d6f0d5b mips: port optimizations to mips n64
This mainly consists of replacing all the pointer arithmatic 'addiu'
instructions with PTR_ADDIU which will handle the differences in pointer
sizes when compiled on 64 bit mips systems.

The header asmdefs.h contains the PTR_ macros which expend to the correct mips
instructions to manipulate registers containing pointers.

James CowgillandMichael Niedermayer eae13eae9d configure, mips: remove MIPS32R2, merging it with MIPSFPU
There are no independant uses of mips32r2 instructions except for the
FPU parts. Due to the heavy use of mips32r2 specifc fpu extensions, I
am guessing the original author intended MIPSFPU to imply MIPS32R2 anyway.

Since these fpu instructions are available on mips64 (non-r2), enable them
there as well.

Also remove the last occurence of HAVE_MIPS32R2 (which is coupled to
HAVE_MIPSFPU anyway).

mips32r2 is left in the list of options form compatability so that using
--disable-mips32r2 doesn't break anything.

James CowgillandMichael Niedermayer a99de50ec7 mips/aacdec: remove uses of mips32r2 specific ext instructions
Removing these removes the dependency of this code on mips32r2 which would
allow it to be used on processors which have FPU instructions, but not r2
instructions (like the mips64el debian port for instance).

James CowgillandMichael Niedermayer 37ffe7f90a mips/aaccoder: use variables instead of using register names directly
On mips64, the registers t[4-7] do not exist. Instead of using a lot of #ifdef
or defines to handle differing register names, use variables and let GCC
allocate the registers automatically (like in the other mips assembly files).

In get_band_cost_ESC_mips, t4 and t5 were renamed to t6 and t7 to avoid a
variable name conflict.

James CowgillandMichael Niedermayer b9de1303a6 mips/acelp_filters: fix incorrect register constraint
Change register constraint on the v variable from = to +. This was causing GCC
to think that the v variable was never read and therefore not initialize it.

This fixes about 20 fate failures on mips64el.

GCC is perfectly happy generating optimized multiplication code on its own for
64-bit arches. GCC refuses to optimize the loongson code when in 32-bit mode,
so I've left that.
