CPP substitution isn't made inside " ", but we need " " when using , in a gas macro argument

Modify HIGH_REGS macro to store/load only one range of registers
When the range isn't contigous (in MC_put_x_8*), shift registers to make
it contigous (r4 and r5 are now unused by these functions)

FS#11335 by me: make ARM assembly functions thumb-friendly

2010-06-11T04:41:36+00:00

We can't pop into pc on ARMv4t when using thumb: the T bit won't be
modified if we are returning to a thumb function
Code running on ARMv4t should use the new ldrpc / ldmpc macros instead
of ldr pc, [sp], #4 and ldm(cond) sp!, {regs, pc}
No modification on pure ARM builds and ARMv5+

Note: USE_THUMB is currently never defined, no targets can currently be
built with -mthumb, see FS#6734

Improve motion compensation for ARM: * Use less registers in the simple copy routines -> less stack usage. * Save a few instructions in constants + jumptable handling. * ARM6 optimisations. Unfortunately we can't just use uhadd8 because that rounds down, while we have to round up.

Bring libmpeg2 portions that we use up to date with the latest libmpeg2 CVS. Fix up some file headers and add a revision history to the libmpeg2 files detailing to which CVS file revisions things were synced. This makes it easier to start in the right place by hand in the future. Hopefully no mistakes and everything works. :-)

mpeg2dec in mpegplayer: Do a little code slashing and organizing. Much more to come I think.

optimized motion compensation for ARM from the mplayer-w100 project. Elefants Dream plays back 2.3fps faster on the Gigabeat
