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.
2019-10-053DS: Switch from svc* to the thread* APIJustin Weiss
svcCreateThread doesn't fully set up thread vars, which causes svcBreaks / crashes when calling certain functions -- reentrant ones, for example. threadCreate, etc. are higher-level functions that do all the correct setup and cleanup. Since we're treating the thread structure as opaque, calling it an int_32t seems OK.
2016-01-16(3DS) - remove provileged services enabling code, it should be done byaliaspider
the frontend instead. - dynamically allocate the recompiler cache, this will allow using the recompiler even when the .bss section is relocated far from the .text section (for example when using the hombrew loader).
