Remove unnecessary use of std:: prefix in spirv_msl.cpp.
Use typedef instead of #define.
spirv-cross deprecate --metal CLI option and replace with --msl option.
CompilerMSL accesses options using same design pattern as CompilerGLSL and CompilerHLSL.
CompilerMSL support setting VA & rez binding specs via either constructor or compile() method overload.
CompilerMSL support single UBO packing and padding in single pass.
spriv_cross app (main.cpp) supports turning off UBO packing and padding via command line option.
Add MSL UBO alignment test shader.
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.
Compiler MSL support DimBuffer as image dimension.
CompilerMSL check texture coordinate result type dimension before adding swizzles.
Update MSL reference shaders affected by this update.
Don't emit automatic sampler when using texture read().
Convert tex coords to uintN() when using texture read().
Emit face when read()ing cube textures.
Do not emit function prototypes. If secondary functions are used,
suppress compiler -Wmissing-prototypes warnings.
Refactor Compiler::emit_function_prototype() functions to simplify.
Rename Compiler_msl::CustomFunctionHandler to OpCodePreprocessor, and
Compiler_msl::register_custom_functions() to preprocess_op_codes()
to perform more generic preprocessing.
Add space between dynamic header lines and fixed header lines.
Combine all vertex attributes into a single stage_in structure.
Remove unneeded structure members from MSLConfiguration, MSLVertexAttr and Meta::Decoration.
Remove unneeded CompilerMSL functions that supported struct offsets and padding.
CompilerGLSL add to_function_name() and to_function_args() functions to organize
structure of emit_texture_op() function.
CompilerMSL add support for MSL gather(), gather_compare() and sample_compare() functions.
Make Compiler::OpcodeHandler and Compiler::traverse_all_reachable_opcodes protected
instead of private, for use by subclasses.
Add CompilerMSL::CustomFunctionHandler and traverse_all_reachable_opcodes() to detect
active opcodes that require the output of a custom function.
CompilerMSL::custom_function_ops use std::set to retain ordering to improve testability.
CompilerGLSL builtin_to_glsl() function outputs gl_ClipDistance for BuiltInClipDistance
builtin, and includes builtin code in output when handling unknown builtin code.
CompilerMSL uses type ID instead of type object where appropriate to support array types,
where type.self is not consistent with actual type ID, plus support array stride calc
even when not explicitly set by SPIR-V code.
For output consistency, CompilerMSL prefers use of standard builtin names over specified
names, and output builtins qualified with output struct while in entry function.
Previously, we would generate parentheses proactively when generating
binary ops, however, this leads to uglier code and hits warnings in
compilers when used as a conditional.
Add CompilerMSL emit_instruction() and emit_glsl_op() functions
to handle MSL-specific operation and function definitions.
Remove CompilerMSL emit_msl_defines() function.
Use entry point name if no function name provided.
When flattening in/out structs, qualify member names with struct name.
Fix issue when determining declared size of struct types.
Refactor use of m_ name prefix.
Identify header defines in MSL code.
- adds some common macros that correct for intrinsic differences
- adds some inline functions to adapt for GLSL terms
- injects structure member names when the original SPV has been stripped - there is another way to use the correct temporarily assigned member name, but using m_<id> based on the inside SPV code yields metal code that more correctly maps to the original SPV opcodes/slots.
The size of an array can be a specialization constant or a spec constant
op. This complicates things quite a lot.
Reflection becomes very painful in the presence of expressions instead
of literals so add a new array which expresses this.
It is unlikely that we will need to do accurate reflection of interface
types which have specialization constant size.
SSBOs and UBOs will for now throw exception if a dynamic size is used since it
is very difficult to know the real size.
