This gets Vulkan support working on macOS if the Vulkan SDK and MoltenVK are available. All current Vulkan tests except particle_life pass with Vulkan on macOS with DXC, and sign.32.test fails with Clang.

These changes are not actually needed, I just didn't have the linkage and paths correct.
This seems to be working, although it's not great that the library is in a weird SDK path...

Particle life is probably harder, but this one feel like we should have a follow up task to figure out what is going wrong.

This refactores handling of extensions and layers to support variable arrays of extensions and layers based on querying for availability.

I converted this PR to a draft because as much as I would like this to work, it is failing like crazy across a lot of tests right now. It looks like bugs in the SPIRV->Metal translator as well as MoltenVK doing additional API validation that other drivers don't seem to be doing. I'll revisit this in the future, but for now... it's going to just sit around. |
