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.
OSX 10.14 broke (?) how overload resolution works,
so overloading e.g. dot(float3, packed_float3) no longer works.
Fix this by unpacking expressions before various func ops.
This fix might need to be applied elsewhere, but do so later if needed.
- The HLSL compiler now has its own list of keywords in addition to
the ones from GLSL.
- Added "buffer", "precise", and "shared" to the GLSL keywords.
Bug: OpLoad fails when loading an interface struct directly, followed by
OpCompositeExtract. This should be fixed, but not critical enough to
block this PR.
Emit input struct assignment by assigning member by member from stage_in struct.
Map qualified member name from pointer type, not base type.
Add Comiler::expression_type_id() function, similar to expression_type().
Remove unsupported sampler1DShadow from shaders-msl/frag/texture-proj-shadow.frag.
Improve error message response from unsupported depth texture formats.
Fix several integer cast warnings in unrelated code.
Run ./format_all.sh on unrelated files.
Support BuiltInFragDepth.
Emit interface block for StorageClassUniformConstant.
Throw exception when output or fragment input structs contain matrix or array.
Dynamically created interface structs sorted by location number instead of alphabetically.
Add Compiler::is_array() function.
Add bool members is_read and is_written to SPIRType::Image.
Output correct texture read/write access by marking whether textures
are read from and written to by the shader.
Override bitcast_glsl_op() to use Metal as_type<type> functions.
Add implementations of SPIR-V functions inverse(), degrees() & radians().
Map inverseSqrt() to rsqrt().
Map roundEven() to rint().
GLSL functions imageSize() and textureSize() map to equivalent
expression using MSL get_width() & get_height() functions.
Map several SPIR-V integer bitfield functions to MSL equivalents.
Map SPIR-V atomic functions to MSL equivalents.
Map texture packing and unpacking functions to MSL equivalents.
Refactor existing, and add new, image query functions.
Reorganize header lines into includes and pragmas.
Simplify type_to_glsl() logic.
Add MSL test case vert/functions.vert for added function implementations.
Add MSL test case comp/atomic.comp for added function implementations.
test_shaders.py use macOS compilation for MSL shader compilation validations.
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.
In some cases, the compiler decided to emit continue block first,
which invalidated the expressions used by the condition.
Parameters to functions can be evaluated in any order which caused
"random" behavior.
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.
