Enhance MSL testing and add numerous MSL test cases. Add to suite of MSL tests and references any existing GLSL tests that successfully convert GLSL->SPIRV->MSL and compile as MSL. test_shaders_helper() ignores hidden files that start with '.', to avoid accidentally finding hidden OSX files such as .DS_Store. Use xcrun to compile MSL shaders instead of hard-coded path to Metal compiler. Wrap calls to xcrun in exception handling to ignore if Xcode not installed. For MSL tests, move call to validate_shader_msl() to after call to regression_check() to allow a converted MSL shader to be saved for manual review even if it doesn't successfully compile as MSL. 2017-01-31 03:55:21 +00:00			`#include <metal_stdlib>`

CompilerMSL support matrices & arrays in stage-in & stage-out. Support flattening StorageOutput & StorageInput matrices and arrays. No longer move matrix & array inputs to separate buffer. Add separate SPIRFunction::fixup_statements_in & SPIRFunction::fixup_statements_out instead of just SPIRFunction::fixup_statements. Emit SPIRFunction::fixup_statements at beginning of functions. CompilerMSL track vars_needing_early_declaration. Pass global output variables as variables to functions that access them. Sort input structs by location, same as output structs. Emit struct declarations in order output, input, uniforms. Regenerate reference shaders to new formats defined by above. 2018-06-12 15:41:35 +00:00			`struct main0_out`
