delegate to previous signal handler, proper abort for win32
arm32: use builtin gcc __clear_cache
dyna/driver.cpp: no need for a code buffer in win32, cleanup
* Add audio arm64 cpp into Xcode project
* Build universal binary for SDL2 also
* Add vixl aarch64 dependency + build arm64 in cmake
* hardcode pagesize for M1 CPU
* Use `MAP_JIT` and toggle between RX and RW
* add pthread.h for cmake
* Disable audio dynarec temporary
* Enable aica arm dynarec
* Supports `br` with condition
* Dynamic linker flag for libSDL2.a since Homebrew path is different on arm (for xcodeproj)
* Fallback path for Intel
* de-dup for arm64, allow cross compilation on both Intel and Apple Silicon Mac
* Rename WriteProtect() to JITWriteProtect(), Move JITWriteProtect from arm7_rec to arm7_rec_arm64
* Remove CodeCache memset
* Remove keyboard_device.cpp from xcodeproj
* Use hard tab
* Update libchdr to support compiling on M1 (thanks @scribam)
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
linux: look for legacy ~/.reicast and ~/.reicast/data
else look for ~/.config/flycast and ~/.local/share/flycast
and ~/.config/reicast and ~/.local/share/reicast
(defaults to flycast)
look for bios files in home folder and data folders (android, windows
,macos), then in game folder.
on linux, search in /usr/share/flycast and /usr/local/share/flycast and
legacy locations
Tested: Both with and without the feature, works only for x64 CPUs for
now, but supported in both windows and linux (see vmem implementation
for it, using mem-mapped files).
