|
|
|
|
v2019.0 2019-06-04

|
|
- Rejects bad modules by running the SPIR-V validator first
|
|
- Skips exception-heavy SPIRV-Cross SPIR-V parser
|
|
- Support NV extensions for shader stages

|
|
- Stop running tests on VS 2013 (googletest no longer supports VS2013)
|
|

|
|
to target environment if they are different. This only works for WebGPU0
|
|
and Vulkan 1.1.
|
|
Fixes:
|
|
#499: In HLSL compilation, relax layout and logical pointer validation rules
|
|
prior to running the legalization recipe.

|
- Support NVIDIA Turing extensions. Requires updated Glslang and SPIRV-Tools.
|
|

|
- Add SONAME=1 property to shared library
|
|
- Support GN build for Chromium
|
|
Fixes:
|
|
#469: Add virtual dtor to classes with virtual functions.
|

|
|
|
|
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 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.
|
|
|
|

|
|
- 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
|
|

|
|
glslc
|
