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.
They might potentially be used as part of OpStore in the SPIRV-Tools
inliner in some cases.
Implement these as declared variables but without any initializer.
CompilerGLSL type_to_glsl() and image_type_glsl() functions support optional object ID.
Add SPIRType::Image::access member to support SPIR-V OpTypeImage access qualifier.
Remove SPIRType::Image::is_read and ::is_written members.
Use DecorationNonReadable and DecorationNonWritable to mark read/write access for image variables.
CompilerMSL emit access qualifiers per image variable, instead of per image type.
CompilerGLSL and CompilerHLSL behaviour is unchanged.
WebGL supports lod texture funcs only in fragment
shaders but SPIR-V supports only lod texture funcs
in vertex shaders. This reverts calls which were
forced (infered from using a 0 constant) to use
an lod to plain calls in vertex shaders when
using legacy es.
spirv_msl optionally add padding and packing to allow MSL
struct members to align with SPIR-V struct alignments.
spirv_cross add convenience methods for testing Decorations.
spirv_glsl replace member_decl() function with new emit_stuct_member().
Allow struct member types to be marked as packed via DecorationCPacked decoration.
To extract a column from row-major matrix, we need to do a strided load one
component at a time. In this case flattened_access_chain_offset still returns
the offset to the first element, but the stride is equal to matrix stride
instead of vector stride.
For this to work, we need to pass matrix stride (and transpose flag) through,
similar to how matrix flattening works.
Additionally slightly clean up recursive flattened_access_chain structure -
specifically, instead of deciding mid-traversal that we need matrix stride
information, we can just pass the matrix stride through - for access chains
that end in matrix/vector this gets us what we need, and for access chains
that end in structs the flattened_access_chain_struct code will recompute
correct stride/transposition data to pass through further.
