Revision history for Shaderc
v2018.0-dev 2018-02-27
- Start v2018.0-dev
- Support -fhlsl_functionality1 (also -fhlsl-functionality1)
v2017.2 2018-02-27
- Add a shared library version of libshaderc
- Support GLSL 4.6 and ESSL 3.2
- Fail compilation if a resource does not have a binding.
- Add options for automatically setting bindings for (uniform) resources that
don't have bindings set in shader source.
- Add options for automatically setting locations for pipline inputs and outputs.
- Add option for using HLSL IO mappings as expressed in source.
- Add options for setting resource binding base numbers.
- Add option to use HLSL resource register numbers for bindings.
- HLSL compilation now defaults to HLSL packing rules.
(This change is inherited from Glslang commit 7cca140.)
- HLSL compilation runs SPIR-V "legalization" transforms to reduce
manipulation of opaque handles (e.g. images), to satisfy Vulkan rules.
- Adapt to Glslang generator version numbers:
- To 2: a fix for code generation for atomicCounterDecrement.
- To 3: change memory barrier semantics masks
- To 4: generate more access chains for swizzles
- CMake install rules uses GNUInstallDirs. For example, install to lib64
when that is the norm for the target system.
v2017.1 2017-03-10
- Add option to automatically assign bindings to uniform variables
that don't have an explicit 'binding' layout in the shader source.
- Enable NVIDIA extensions by default in GLSL compilation
- README mentions language bindings provided by 3rd parties.
- README describes the known-good branch on GitHub
- Fixed examples in shaderc.h; added C API use to examples/online-compile
- Fixes issues:
#289: Don't output an object file when compilation fails.
#296: Enable use of the CMake in Android Studio.
v2016.2 2016-12-13
- Describe Shaderc's level of stability.
- Support HLSL compilation, exposing functionality in Glslang.
- Supported in C, C++ API
- glslc accepts "-x hlsl", and assumes .hlsl files are HLSL.
- glslc accepts "-fentry-point=<name>" to set entry point name,
overriding default value "main".
- Support setting shader resource limits in C, C++ APIs, and in
- glslc adds -flimit=<setting>
- glslc adds --show-limits to display defaults and valid resource
limit syntax.
- glslc adds "-flimit-file <file>" support to read Glslang resource
configuration files, i.e. the output of "glslangValidator -c".
- Enable AMD extensions by default in GLSL compilation
- Fixes issues:
#281: Work around Android build issue with abspath on Windows
#283: Increase default maxDrawBuffers to 4, to match Vulkan/GLES3.0
v2016.1 2016-10-12
- C API for assembling now takes an options object
- Support compilation options to optimize for size.
- Maintain compatibility with recent SPIRV-Tools and Glslang versions.
- Update examples.
- Build cleanups.
- Fixes issues:
#238: Fix invocation of python scripts during build
v2016.0 2016-07-07
- Adds v<year>.<index> versioning, with "-dev" suffix to indicate work in
progress. The intent is to summarize and report functionalities more easily
for incorporating into downstream projects.
- Summary of functionalities (See the for more details):
- Provides libraries and command line tools for generating SPIR-V modules
- Supports GLSL source code or SPIR-V assembly as input
- Supports SPIR-V binary or assembly text as output
- Command line options follow GCC/Clang conventions
- Supports various semantics (OpenGL, OpenGL Compatible and Vulkan)
- Supports #include
- Supports user-defined macros
- Supports dependency information dumping
