This case fails slightly less silently now.
Also make ENABLE_OPT depend on ENABLE_SPIRV, since when there's no
SPIR-V optimization doesn't really make sense.
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.
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
This PR significantly reworks the way glslang is versioned.
Instead of committing changes to the `GLSLANG_MINOR_VERSION` define in
`glslang/Public/ShaderLang.h`, and using `make-revision` to generate
`GLSLANG_PATCH_LEVEL` in `glslang/Include/revision.h`, all version
information is now derived from the new `CHANGES.md` file.
`CHANGES.md` acts as the single source of truth for glslang version
information, along with a convenient place to put all release notes for
each notable change made.
`CHANGES.md` is parsed using the new `build_info.py` python script.
This script can read basic template files to produce new source files,
which it does to read the new `build_info.h.tmpl` to generate (at build
time) a glslang private header at
`<build-dir>/include/glslang/build_info.h`.
I've written generators for each of the CMake, Bazel, gn, and
`Android.mk` build scripts.
The new version code conforms to the Semantic Versioning 2.0 spec.
This new version is also used by the CMake rules to produce versioned
shared objects, including a major-versioned SONAME.
New APIs:
---------
* `glslang::GetVersion()` returns a `Version` struct with the version
major, minor, patch and flavor.
Breaking API changes:
---------------------
* The public defines `GLSLANG_MINOR_VERSION` and `GLSLANG_PATCH_LEVEL`
have been entirely removed.
* `glslang/Public/ShaderLang.h` and `glslang/Include/revision.h` have
been deleted.
* Instead, `<build-dir>/include/glslang/build_info.h` is created in
the build directory, and `<build-dir>/include` is a CMake `PUBLIC`
(dependee-inherited) include directory for the glslang targets.
* `<build-dir>/include/glslang/build_info.h` contains the following
new #defines:
`GLSLANG_VERSION_MAJOR`, `GLSLANG_VERSION_MINOR`,
`GLSLANG_VERSION_PATCH`, `GLSLANG_VERSION_FLAVOR`,
`GLSLANG_VERSION_GREATER_THAN(major, minor, patch)`,
`GLSLANG_VERSION_GREATER_OR_EQUAL_TO(major, minor, patch)`,
`GLSLANG_VERSION_LESS_THAN(major, minor, patch)`,
`GLSLANG_VERSION_LESS_OR_EQUAL_TO(major, minor, patch)`
* The CMake install output directory contains a copy of
`build_info.h` at: `include/glslang/build_info.h`
* Python3 is now always required to build glslang (likely always
required for transitive dependency builds).
Default to `-fvisibility=hidden`, and annotate the public glslang interface with `GLSLANG_EXPORT` to change the visibility of these cherry-picked symbols to default.
This is also used by Windows builds for `__declspec(dllexport)`-ing the public DLL interface.
This allows us to classify API changes into those that are publicly backwards compatible, and those that are not.
Note that `libSPIRV` will likely need similar treatment.
Issues: #2283, #1484
Analogous to gcc, -g0 would strip all debug info. This is done
regardless of whether optimizations are enabled.

* Add Shared/Std140 SSBO process & top-level array elements related
process
1.Add process options for shared/std140 ssbo, following ubo process
2.Add IO Variables reflection option, would keep all input/output
variables in reflection
3.Add Top-level related process, fix top-level array size issues,
following spec
4.Split ssbo/ubo reflection options, merge blowup expanding all into
function blowupActiveAggregate to allow other functions keep same entry
format.
Add options in StandAlone and test symbols.
1. Add options in StandAlone for std140/shared ubo/ssbo and all io variables reflection.
2. Add test for ssbo. When EShReflectionSharedStd140SSBO turns on, generated symbol and output would be different, to remind the difference. Defaultly disabled and nothing would change, nor blocking normal test.
* Add options in runtest script, refresh test results.
Add options in StandAlone:
--reflect-all-io-variables --reflect-shared-std140-ubo --reflect-shared-std140-ssbo
refresh test results.
Now the index, size of unsized array are expected.
