given a NaN operand, will return the other operand. Similarly, the

- Replaced shaderc_spvc_compile_options_set_shader_model with
- Compiler initialization and shader generation moved into seperate calls
- Seperated return codes from shaderc ones
- Many small API changes
- Improvements to testing
- Refactoring and clean up of
- Seperation of expectations into known failures, known invalids, and cases
that need investigation
- Tweaks and fixes to substantially increase passing cases
- Added support for running tests using spvc IR generation
- Infrastructure
- Update DEPS with cross-verified commits from associated repos.
- Add utils/roll-deps
- Infrastructure:
- Removed Appveyor artifacts link
- Improvements and clean up of DEPS rolling scripts
- Enabled warnings about implicit fallthrough
- Enabled improper semicolon warnings
- Restricted -fPIC to platforms that support it
- Converted remaining scripts to use Python 3
- Replaced nosetest with unittest

- Removed unsupported Unicode characters
- Fixed detection of spirv-headers directory
#666: Update Docker file to use Python3
v2019.0 2019-06-04
- Add optional spvc, libshaderc_spvc as wrapper around SPIRV-Cross:
- Rejects bad modules by running the SPIR-V validator first
- Skips exception-heavy SPIRV-Cross SPIR-V parser
- Support NV extensions for shader stages
- Require SPIRV-Tools and SPIRV-Headers with SPIR-V 1.4 support
Build support:
- Use KhronosGroup/glslang instead of google/glslang
- Stop running tests on VS 2013 (googletest no longer supports VS2013)
- Require Python3 for building
- Support Chromium's GN build system
- Kokoro build fixes
- Cmake build fixes: Only build subdirs if those targets are not yet defined
- Use from Glslang
- Dockerfile gets re2 and effcee sources
- Fixes for newer googletest
- Add address sanitizer presubmit bot
- Generate config files for pkg-config
- Add option to specify source environment. Spvc will transform from source
to target environment if they are different. This only works for WebGPU0
and Vulkan 1.1.
#499: In HLSL compilation, relax layout and logical pointer validation rules
prior to running the legalization recipe.
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
#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.

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
