Metal example doesn't compile: LLVM CODE GEN FAILED for build_shaders
I'm getting an error building Metal examples.
macOS 13 beta 4 arm64 (kernel version 22.0) Odin dev-2022-08:a0135080 LLVM 14.0.6 (same error with LLVM 13) RAM: 32768 MiB
Please note that this source change would have to be made first before you see the below output:
