This saves a few cycles because gcc stores / loads srcMSB when using ARM-optimized lighting.

2020-02-24Fix dynarec crashes on 3DSJustin Weiss
After the dynarec writes new instructions, it has to flush the instruction and data caches. Some of these flush operations are privileged on the 3DS, so the clear cache functions have to run through svcBackdoor. The Nintendo implementation (and CFW reimplementation) of svcBackdoor has a problem where interrupts and context switches will cause crashes. Even though we can disable interrupts in the flush function, there's still a window of time between svcBackdoor being called and the function being run where an interrupt will corrupt the stack. Luma3DS implemements a svcCustomBackdoor call we can use that also runs a function in supervisor mode, but uses an implementation that avoids this problem.

Fix second instance runahead
2020-02-19Use a more lightweight reset method for lightrecZachary Cook
Reset is common when using runahead, this seems to prevent crashes when resets occur rapidly.
2020-02-18Add fallback addresses so second instance runahead can workZachary Cook
Also prefer MAP_FIXED_NOREPLACE over MAP_FIXED, as it won't remove old memory maps

Replace existing gte_divider with MAME's version
2020-02-12Replace existing gte_divider with MAME's versionPaul Cercueil
The original code did not have a license header, and as a result was licensed under the GPLv2 which means that it was impossible to link it with LGPL code. The new code originates from MAME and is under a BSD-3-Clause license, which is GPL-compatible, and also much cleaner. Signed-off-by: Paul Cercueil <paul@crapouillou.net>

2020-02-08cdrom: add missing BCD->int convert in cdrFreeze()Daniel Silsby
For some Eboot .PBP game images, when loading a savestate, a zlib error like 'uncompress failed with -5 for block 5383, sector 86132' would be output to stdout/stderr. The savestate would still be playable, though. Traced it down to cdrFreeze() failing to convert cdr.Prev from BCD->int when calling ReadTrack(). Note that the odd 'cdr.Prev[0]++;' line seems to be someone's hacky way of forcing ReadTrack() to avoid skipping what it thinks is a duplicate sector read.
2020-02-08gpulib: fix out-of-bounds reads in do_cmd_buffer()Daniel Silsby
When gpu.cmd_buffer[] is filling up, and the last 1 or 2 words in it are the beginning of a new vram read/write cmd, do_cmd_buffer() would access out-of-bounds, reading garbage pos/size data. Fixes corrupted gfx in this PS1 .exe test utility: https://github.com/PeterLemon/PSX/tree/master/CPUTest/CPU/LOADSTORE/LW (This and all similar tests on Peter's site). Note that gfx access in this utility is done entirely through cmds given through GPUwriteData(), i.e. direct CPU->GP0 stores, not DMA.
