Atari's mintelf platform has ELF support but its libc does not provide
__cxa_atexit / __cxa_finalize, so -fuse-cxa-atexit cannot be used out of
the box. Add a minimal shim (plus a __dso_handle definition for the main
executable) so plugins can register and finalize their function-local
static destructors per DSO on unload.
Note: earlier version ran __cxa_finalize from the host via
findSymbol("__dso_handle"). That works as long as exactly one
__dso_handle ends up in the plugin's symtab (the plugin's own).
When the main binary also defines __dso_handle (so the host's
function-local statics can link with -fuse-cxa-atexit), it breaks: the
plugin link uses --just-symbols=<main binary> and imports that as a
second __dso_handle, and findSymbol can then return the host-imported
one instead of the plugin's own. The two addresses differ, so
__cxa_finalize matches nothing.
The plugin-side helper avoids the ambiguity on every target by using
whichever __dso_handle the plugin's own code already resolved against --
the same one embedded in its __cxa_atexit calls. (PSP2's plugin runtime
has always called __cxa_finalize from inside the plugin for the same
reason; see backends/plugins/psp2/plugin.cpp.)
It would appear that Oboe is the new audio library.
It's way more complex to handle (especially on really old devices), but
it brings low latency.
Oboe also comes with its share of warkaround to apply that have no
real doc... A fine piece of software...
Integrate the existing CoreMIDI implementation used in the MacOS
backend into the iOS7 backend. The CoreMIDI framework is available
from iOS 4.2 and tvOS 15.0.
This allows ScummVM to detect external MIDI devices connected to
the device running ScummVM and to be selected as MIDI music output
device.
The NSSpeechSynthesizer API has been deprecated in recent macOS versions.
This commits adds an implementation using the newer AVSpeechSynthesizer,
available since macOS 10.14. The new implementation is only used when
building for Apple Silicon. In theory we could also use it when building
for 64 bit Intel macs and targetting macOS 10.14 or above, but there is
not much benefit in doing so.
As a bonus it should also work on iOS.
A new USE_HTTP define is created to indicate that an HTTP backend is
available (using either libcurl or emscripten platform).
USE_CLOUD now only builds cloud providers storage support, while
USE_SDL_NET determines if a local web server is built.
USE_LIBCURL is now only used when the feature really depends on libcurl
(that is lobby support for Scumm HE).
- Introduce AtariSurface: a surface which represents either a
bitplane-based or pixel-based surface (on SuperVidel, as an inherited
SuperVidelSurface). Screen::surf / Screen::offsettedSurf are its
instances.
- Graphics::Surface::create / free now handle all Atari-related surfaces
via dlmalloc: ST RAM (TT/Falcon), VRAM (SuperVidel - 0xA0xxxxxx) and
VRAM for generic surfaces (SuperBlitter - 0xA1xxxxxx or ST/TT RAM).
This allowed me to remove all the hacky stuff from atari-graphics and
atari-superblitter.h.
- blit-atari.cpp now contains only blitting code
(SuperBlitter/move16/fallback), SV code is in
atari-supervidel.{cpp,h}.
- Take advantage of Common::ScopedPtr and Graphics::ManagedSurface's
dispose flag for Screen::surf as well Graphics::ManagedSurface's
ownership for Screen::offsettedSurf.
- Improve recoverability if an error/assert happens in
AtariGraphicsManager's c-tor/d-tor.
- seamless resolution/palette switching (at least in theory, it still
isn't artifact-free, no clue why)
- bugfixes (shake offset, some s_screenSurf corner cases)
- simplification the triple-buffering code
SDL audio init will fail on Windows if all audio output devices are disabled.
Only about 10 engines are checking for this case and numerous pieces of common code (EmulatedOPL, VideoDecoder) fail as well, so this acts as a fallback to prevent instability.
