Expose GLSLANG__TESTS and GLSLANG_ENABLE_INSTALL as options
that can be controlled from an enclosing project, or from the
command line.
They retain the prior default behaviour. In particular, if Glslang
is not the top level project, then they default to OFF.
Fixes: #3507
The dependency was only because of the SpvOptions struct which is used
in both, but really is part of the glslang public interface and should
be in the public GlslangToSpv.h header.
The debug options passed down from the public ShConstruct* functions to
internal code is unused. This change removes the internal debugOptions
fields and attempts to make it more obvious these fields are not used.
This change does not change the public-facing interface.
This change also adds the -Wshorten-64-to-32 warning to the StandAlone
build in order to avoid unwanted 64-to-32 bit conversions in the future.
Closes#3348.
Adds the --no-link option which outputs the compiled shader binaries
without linking them. This is a first step towards allowing users to
create SPIR-v binary, non-executable libraries.
When using the --no-link option, all functions are decorated with the
Export linkage attribute.
There should not be a '/' after $ENV{DESTDIR} in the cmake install script.
This change also:
- Uses lukka/get-cmake github action consistently across jobs
- Add the glslang binary to the continuous deployment archive
The usage of GetGlobalLock/ReleaseGlobalLock/InitGlobalLock is replaced
by std::lock_guard which is available as of c++11, and the functions are
removed from the OSDependent ossource.cpp files.
The standalone glslang binary now explicitly depends on OSDependent, as
nothing in in the glslang library uses those functions anymore and they
are not implicitly picked up by the linker.
The `spirv-remap` tool now supports two output modes:
* Outputting one or more inputs to a single directory -- the previous
behavior
* One output file per input -- new behavior.
The FindPythonInterp and FindPythonLibs modules, which have
been deprecated since CMake 3.12, have been removed by policy
CMP0148. Port projects to FindPython3, FindPython2, or FindPython.
On QNX, pthread APIs are provided as part of libc and a separate pthread
library does not exist.
This change updates the makefile of glslang to not link with pthread on
QNX, thereby enabling glslang to be built for QNX platforms.
Commit fbe9a23baf erroneously
only added SOVERSION to libglslang.so, but none of the others
that are produced.

New interface allows users to generate ResourceLimits for interface so
that additions to TBuiltInResource do not break the ABI.
Users should use the glslang-default-resource-limits library and the
Public/ResourceLimits.h header. Similar changes have been made to the
C interface. Use Public/resource_limits_c.h.
Fixes#2822
Implement NonSemantic.Shader.DebugInfo.100 debug instruction generation.
These instructions will be generated under the -gV and -gVS command line options. These instructions enable source-level shader debugging with Renderdoc.
This is an alpha release of this capability. Additional improvements are forthcoming. Use and feedback are welcome.
Added following updates to GL_EXT_mesh_shader implementation:
1. Added SPIRV and GLSL test cases
2. Added checks to ensure NV and EXT mesh shader builtins cannot be used interchangeably.
3. Updated the language name by removing the postfix "NV" to MeshShader and TaskShader.
4. Added checks for grammar checking to comply with the spec.
5. Added gl_NumWorkGroups builtin to Mesh shader
6. Fixed data type of gl_PrimitiveLineIndicesEXT and gl_PrimitiveTriangleIndicesEXT
7. Added new constants to the resources table
8. Updates to handle new storage qualifier "taskPayloadSharedEXT"
9. Updated test cases by replacing "taskEXT" with storage qualifier "taskPayloadSharedEXT"
Addressed Review comments
1. Fixed instruction description used by glslang disassembly.
2. Updated OpEmitMeshTasksEXT as per spec update
3. Fixed implementation that errors out if there are more then one taskPayloadSharedEXT varjables.
4. Fixed miscellaneous error logs and removed unwanted code.
SPIRV 1.6 related build failure fixes
- Update SPIRV header to 1.6
- Fix conflict wiht SPIRV 1.6 change, where localSizeId is used for execution mode for mesh/task shaders
Enable SPIRV generated for EXT_mesh_shader to be version 1.4
GL_EXT_mesh_shader: Add checks for atomic support and corresponding test cases
Specifically, make GLSL link error messages more specific and output
only information relevant to the error.
Also change type printing to more closely reflect GLSL syntax. This
is the default for link error messages, but must me enabled with the
new option --enhanced-msgs for compilation error messages.
Also with --enhanced-msgs, only emit one error message per source
line.
Also update known goods to Vulkan 1.3 support
Also re-enable SPIR-V 1.6 tests with vulkan1.3 target
Also re-cache SPIRV 1.6 header which somehow regressed back to 1.5
- Reverted public function interface changes for C++.
- Added override member variable to TShader.
- Added accessor TShader::setOverrideVersion.
- Reverted changes to tests.
This change list allows a user to override the GLSL version from the
command line or through the C and C++ interfaces. This will override the
override happens in ProcessDeferred() before DeduceVersionProfile() so
the process should still error out if the version is insufficient for
the shader code.
- Added --glsl-version <version> to CLI.
- Added parameter to route glslVersion as override version to
preprocessor and parse functions to C++ interface.
- Updated C interface with function to override GLSL version.
Add command line support which enables the following behavior:
- Remap discard
Map discard to DemoteToHelperInvocation for HLSL shaders. Map to
OpTerminateInvocation for GLSL shaders.
- Decorate HelperInvocation with Volatile
- Use localSizeId for execution mode
WorkGroupSize is deprecated in spirv1.6
Also update known goods to SPIRV 1.6
