* update retro host to pass it's own dlsym-esque function to glad
* arg1 is not optional for CALL_COND
* clean up caller-saved register saving in load store thunks
* use c-style casts in x64 backend
* support imm data arguments to STORE_*
validate type constraints to emitter functions
* legalize constants during register allocation
* added caller-saved register support
* standardized register names in emitters
use macros for terseness
* initial take at adding constraints to emitter functions
* removed unused ir op
* ensure -Wall comes before -Wno-*
* update DMA status registers immediately, not when the interrupt timer ends.
this avoids games trying to suspend the DMA transfers due to a lack of
progress
* pass COMPILER_* variables as preprocessor defines
* break out of emu_run_frame loop based on vblank event, not render event. this
fixes games which render a loading / notice screen once (not every frame) and
don't render again until the user presses a button
* convert incoming TA surfaces from tristrips to triangles
merge incoming TA surfaces when possible
* don't push empty surfaces for modifier volumes
* fix issue where data is fetched before ea is calculated in movbm, movwm and movlm instructions
* use the host clock to smooth out frame timings when audio latency is high
* remove inter-frame input polling
* added temporary options
* moved trace.c
* removed extended basic block functionality from optimization passes
* add VIXL_CODE_BUFFER_STATIC to vixl
* remove uintptr_t use in x64 backend
use register aliases in x64 dispatch
* split up x64 backend into x64_emitters.cc
* added individual contributor license agreement
* added vixl to build
* rename ARM64 to A64
* avoid submitting vertices from discarded surfaces
* allocated a 24-bit depth buffer with SDL
force highp for fragment depth calculations
* add some debug code for calling interpreter fallbacks when emitting sh4 ir
* add arm64 support to linux exception handler
* pass SDL_GL_GetProcAddress to glad's loader to avoid it having to locate the shared library as well
set correct window width / height for android
set correct app dir for android
* add android support to logging
* initial android support
* remove glew source
* replace glew with glad
* make high-level gdrom_* functions return C data structures in LE
* prefix gdrom enums with GD_

* avoid having an empty struct in c (#99)
* Fixes ##98

set arm wave ram to 2mb instead of 8mb
don't mirror arm memory
emit invalid instruction ops in armv3 frontend
be careful to emit blocks even when end address overflows
* fix retest bit rot
* nop on writes to SB_ISTEXT; external interrupts can only be cleared by the external device itself
* fix end address calculation in sh4_frontend_dump_code

don't assert when leadin fad does not equal 45150
* flush stdout before issuing debugbreak

* windows build fixes
* initial hle flash support
* rename exception struct to exception_state to resolve collison in
don't write out flash modifications until program exit
* allow mode 0 tracks as well when loading CDIs
* renamed bios.c to boot.c in preparation for hle bios
* merge sys and core, the distinction between the two is trivial
* moved non-hw code out of hw dir
* moved host code to its own subdir
* fix scaling of trigger inputs broken by recent sdl host update
