When using a non-default sound configuration (such as 6 channels), after
a long time (about 4.5hours for 6 channels at 22050 Hz) an overflow will
occur in `S_TransferPaintBuffer`, causing an out of bounds write into
the dma buffer.
The problematic line is:
```
out_idx = (s_paintedtime * dma.channels) % dma.samples;
```
With `s_paintedtime` large enough, the result of the multiplication will
overflow to a negative number (since `s_paintedtime` is signed), and the
index into the output buffer will be negative.
ranlib errors on older macOS because of arm64 arch in code/libs/macosx/-
libSDL2main.a. Use lipo to extract the library for the specific arch
that is being linked.
The engine function pointer to vmMain used variadic arguments but
the vmMain function in the dylib has explicit arguments. Evidently
the arguments are stored on the stack and/or registers differently.
Found by fretn.
Fix "Architecture arm64 is not supported when cross compiling" and
also be more be more flexible for manually specifying CC or the
osxcross darwin version (which corresponds with a macOS SDK version
to build against).
GL_DEPTH_TEXTURE_MODE defaults to GL_LUMINANCE. Code sets it here as
part of a workaround old nvidia drivers (apparently? the URL in comment
is dead). GL_DEPTH_TEXTURE_MODE was removed in OpenGL 3.0 / 3.2 Core
contexts and may be treated as an error.
The CD key defaulted to spaces. Q3 UI uses text overwrite mode by
default so typing the CD key writes over the spaces. Team Arena UI
uses text insert mode by default so to enter the CD key the user
had to delete the spaces or toggling overwrite mode by pressing
the insert key.
Now the CD key defaults to empty so in Team Arena you can just type
it in.
Printing GL_EXTENSIONS list might be cut off for OpenGL contexts
before 3.0 due to glConfig.extensions_string being a limited length.
Instead get the full extensions list directly.
This was already fixed for OpenGL 3.0 and later contexts.
Using LUMINANCE with OpenGL 3.2 Core contex results in all images being
solid black (in the menu, world, and the console). In the end the whole
screen was solid black except the intro video.
Store images in RGB and RGBA instead. This doesn't affect r_grayscale
visually. If there is issues with it now possibly using compressed
formats, then it would already be an issue for r_grayscale 0.9.
Unlike the Steam and GOG support I'm not doing a registry search as I don't see anything in the registry that would show us the path. If we find more official ways to search for it later we can address that, in the meantime the path is just hardcoded to where it's installed by default.
The ppc arch is the 2.0.1 that was there originaly.
The i386 arch is 2.0.16, now compiled with an SDK later than 10.9 so the Notarization process is cool with it.
So now all post-ppc SDL libraries are 2.0.16.
Also works on Apple Silicon. Specific signing values are in a non-committed file, and the ub2 script only notarizes if a "notarize" flag is passed in on the command line.
NOTE: the SDL dylib currently only has x86_64 and arm64, will need extra work to graft those back in and keep the Notary service happy.
- Reorganized Xcode project
- Added missionpack support to Xcode project
- Incorporated changes from MaddTheSane for Apple Silicon support https://github.com/maddthesane/ioq3
- Built SDL 2.0.14 for Apple Siicon, added to existing SDL dylib
- Built SDLMain for Apple Silicon, added to existing libSDL2main.a
qvmcall64 has its own custom calling convention due to pushing all non-volatile registers to the stack. The game uses set/longjmp which on Windows uses "RtlUnwindEx" to unwind the callstack. qvmcall64 cannot be unwound by default due to the custom calling convention. To allow unwinding, we need to add custom SEH unwind data to the function.
