Validate Metal shaders on OSX with Metal compiler If we run on a system with Xcode installed to a default path, run Xcode Metal shader compiler to validate the generated MSL shader. This uncovers an issue in the existing MSL test - MSL backend currently does not auto-assign attribute locations, which means that translating GLSL shader without location layout produces an invalid MSL which generates "error: 'attribute' index '0' is used more than once". 2017-01-25 06:26:39 +00:00

Add explicit in/out locations everywhere. Needed for newer glslang. With Vulkan semantics for SPIR-V, all locations must be explicitly defined. 2017-06-21 07:39:08 +00:00			`layout(location = 0) out vec3 vNormal;`
