Revision history for Shaderc

v2018.1-dev 2018-10-01

v2018.0 2018-10-01

Support -fhlsl_functionality1 (also -fhlsl-functionality1)
Support NVIDIA Turing extensions. Requires updated Glslang and SPIRV-Tools.
Use SPIR-V optimization and HLSL legalization recipes from SPIRV-Tools.
- Pass target environment into SPIRV-Tools code, e.g. from --target-env vulkan1.1
Add SONAME=1 property to shared library
Support GN build for Chromium Fixes:
469: Add virtual dtor to classes with virtual functions.

457: Fix writing SPIR-V binaries to standard output on Windows.

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
- 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

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 README.md 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
