fix(gl): Get running on Adreno 308 (#11467) 28e95e51e7
Adreno 308 had a few issues:
* Crash from drawing too many instances, which we work around by
breaking them up with glFlush.
* Compiler failure from the compiler declaring a 3.1 bulitin in ESSL
3.0, which we work around with a #define.
* The advertised max texture size is 8192, but textures larger than
2048 seem to not work with EXT_multisampled_render_to_texture.
Either way, we shouldn't have any gms larger than 2048 since that's
the bare minimum per the spec. Shrink the larger gms down to 2048.
Rive had an issue as well:
* With EXT_multisampled_render_to_texture but not
KHR_blend_equation_advanced, we were trying to use the same texture
for both msaa and the dstRead. Separate these into their own
textures.

Rive C++ is a runtime library for Rive, a real-time interactive design and animation tool.
The C++ runtime for Rive provides these runtime features:
We use premake5. The Rive dev team primarily works on MacOS. There is some work done by the community to also support Windows and Linux. PRs welcomed for specific platforms you wish to support! We encourage you to use premake as it's highly extensible and configurable for a variety of platforms.
In the rive-cpp directory, run build.sh to debug build and build.sh release for a release build.
If you've put the premake5 executable in the rive-cpp/build folder, you can run it with PATH=.:$PATH ./build.sh
Rive makes use of clang vector builtins, which are, as of 2022, still a work in progress. Please use clang and ensure you have the latest version.
Uses the Catch2 testing framework.
cd tests/unit_tests ./test.sh
In the tests/unit_tests directory, run test.sh to compile and execute the tests.
(if you've installed premake5 in rive-runtime/build, you can run it with PATH=../../build:$PATH ./test.sh)
The tests live in rive/test. To add new tests, create a new xxx_test.cpp file here. The test harness will automatically pick up the new file.
There's a VSCode command provided to run tests from the Tasks: Run Task command palette.
rive-cpp uses clang-format, you can install it with brew on MacOS: brew install clang-format.
Note that if you‘re on MacOS you’ll want to install valgrind, which is somewhat complicated these days. This is the easiest solution (please PR a better one when it becomes available).
brew tap LouisBrunner/valgrind brew install --HEAD LouisBrunner/valgrind/valgrind
You can now run the all the tests through valgrind by running test.sh memory.
If you want to examine the generated assembly code per cpp file, install Disassembly Explorer in VSCode.
A disassemble task is provided to compile and preview the generated assembly. You can reach it via the Tasks: Run Task command palette or you can bind it to a shortcut by editing your VSCode keybindings.json:
[
{
"key": "cmd+d",
"command": "workbench.action.tasks.runTask",
"args": "disassemble"
}
]
