Won't work with all games, but provides a nice way to spend extra CPU to make
a variable framerate game faster (e.g. Spyro or The Last Story), or to make
a game use less CPU at the cost of a lower framerate (e.g. Rogue Leader).
- Get rid of ArmMemTools.cpp and rename x64MemTools.cpp to MemTools.cpp.
ArmMemTools was almost identical to the POSIX part of x64MemTools, and
the two differences, (a) lack of sigaltstack, which I added to the
latter recently, and (b) use of r10 to determine the fault address
instead of info->si_addr (meaning it only works for specifically
formatted JIT code), I don't think are necessary. (Plus Android, see
below.)
- Rename Core/PowerPC/JitCommon/JitBackpatch.h to Core/MachineContext.h.
It doesn't contain anything JIT-specific anymore, and e.g. locking
will want to use faulting support regardless of whether any JIT is in
use.
- Get rid of different definitions of SContext for different
architectures under __linux__, since this is POSIX. The exception is
of course Android being shitty; I moved the workaround definition from
ArmMemTools.cpp to here.
- Get rid of #ifdefs around EMM::InstallExceptionHandler and just
provide an empty implementation for unsupported systems (i.e.
_M_GENERIC really). Added const bool g_exception_handlers_supported
for future use; currently exception handlers are only used by the JIT,
whose use implies non-M_GENERIC, but locking will change that.
- Remove an unnecessary typedef.
It now affects the GPU determinism mode as well as some miscellaneous
things that were calling IsNetPlayRunning. Probably incomplete.
Notably, this can change while paused, if the user starts recording a
movie. The movie code appears to have been missing locking between
setting g_playMode and doing other things, which probably had a small
chance of causing crashes or even desynced movies; fix that with
PauseAndLock.
The next commit will add a hidden config variable to override GPU
determinism mode.
OSD messages can be disabled, while still leaving them in the status bar. This is incredibly useful for certain users, who may wish to see the messages, but do not wish to have them cover up half of the screen. In particular TASers will generally have OSD messages on the screen 100% of the time, and they cover up useful information, making it critical to turn them off. However the messages are still very useful to them, so it's important to have them somewhere.
This reverts 4a16211bae97a42c24ed43cf4174df03d180ac4a.
The concept of a "title bar" / "status bar" shouldn't be a core concept,
so remove the Host_UpdateStatusBar function, and move the code handles
whether to update the status bar or titlebar into DolphinWX.
This is effectively unused, as the window handles that we pass to the
GLInterface are window handles for the frame which isn't ever a real
toplevel window. Host_UpdateTitle is what actually sets the proper title
on the render window.
Now that MainNoGUI is properly architected and GLX doesn't need to
sometimes craft its own windows sometimes which we have to thread back
into MainNoGUI, we don't need to thread the window handle that GLX
creates at all.
This removes the reference to pass back here, and the g_pWindowHandle
always be the same as the window returned by Host_GetRenderHandle().
A future cleanup could remove g_pWindowHandle entirely.
