Enhancements to MSL compute and entry point naming. Support Workgroup (threadgroup) variables. Mark if SPIRConstant is used as an array length, since it cannot be specialized. Resolve specialized array length constants. Support passing an array to MSL function. Support emitting GLSL array assignments in MSL via an array copy function. Support for memory and control barriers. Struct packing enhancements, including packing nested structs. Enhancements to replacing illegal MSL variable and function names. Add Compiler::get_entry_point_name_map() function to retrieve entry point renamings. Remove CompilerGLSL::clean_func_name() as obsolete. Fixes to types in bitcast MSL functions. Add Variant::get_id() member function. Add CompilerMSL::Options::msl_version option. Add numerous MSL compute tests. 2017-11-06 02:34:42 +00:00			`#include <metal_stdlib>`

MSL: Do not generate UnsafeArray<> for any array inside buffer objects. This avoids a lot of huge code changes. Arrays generally cannot be copied in and out of buffers, at least no compiler frontend seems to do it. Also avoids a lot of issues surrounding packed vectors and matrices. 2019-10-24 10:22:30 +00:00			`float3x3 out_data[1];`

MSL: Rewrite how resource indices are fallback-assigned. We used to use the Binding decoration for this, but this method is hopelessly broken. If no explicit MSL resource remapping exists, we remap automatically in a manner which should always "just work". 2019-06-21 10:44:33 +00:00			`kernel void main0(device SSBO2& _22 [[buffer(0)]], uint3 gl_GlobalInvocationID [[thread_position_in_grid]])`
