aica arm x86: use pc-relative addressing to access arm registers
OSX project fix
arm7: add simple ldm/stm handling. optimize arm32 and x64 recs
update CMakeLists.txt and Makefile. finish rebase
This works, but is extremelly hacky. Must be started without attached debugger, lldb doesn't want to let go of EXC_BAD_ADDRESS, but reicast really depends on it getting delivered as SIGSEGV/SIGBUS. Also xcode has a really bad day upon seeing the jit code. Oh well.
There's some dynarec bug that causes color corruption on bios logo/boot triagles, TA crash on ikaruga and infinitive loop on crazy taxi. I'd guess some fp-memory-write thingy, abi, or smth. Too bad.
- Force code to compile in arm mode (arm jit -> thumb mem functions is complicated)
- SIGILL, SIGBUS. Works w/o Mach exceptions and EXC_BAD_ADDRESS
- Code buffers move to __TEXT, munmapped && memmapped to actually work
- Primitive input. Button + start, or left (works to get out of bios date screen)
- Fixup emitter for thumb2/interworking (didn't work though, reverted to arm cc)
- Block Manager: Disable mem saving / page fault alloc-on-demand logic
- Move cycle counter to r11, r9 is not clean on iOS. Remove r11 from reg alloc list
- Cache flushes for iOS
- log to log.txt
- load game.chd
THIS IS A MESS. Sorry @angelXwind :p. We'll have to clean up and merge for r8, but most of the nasty work is there.
What works:
- full init, memalloc, mprotects, etc
- boot
- gles2
What doesn't:
- Exceptions for page faults
- Breaks texture cache
- Breaks dynarec because of fastpath
- segfaults don't work, needs special mach exc_server magic that still eludes me after 5 hours
- Dynarecs. RWX issues, and broken buffer mappings. Also some minnor linking stuff (most of it is taken care of)
- Audio. I just killed it off.
- All of the ui. Was getting in the way of me not knowing how to edit story boards...
- Input
Also, merged branch 'skmp/mac86-hackport' into skmp/ios-wip
Have fun~
