BUILD.gn: Fix fuchsia build (#1944) The Fuchsia platform build and the Chromium one use a completely different set of configs to specify default warnings. The previous version of BUILD.gn worked with Chromium, but failed to build with Fuchsia. This CL fixes the issue by identifying said configs and reusing them consistently.

# Both Chromium and Fuchsia use by default a set of warning errors
# that is far too strict to compile this project. These are also
# typically appended after |cflags|, overriding target-specific
# definitions. To work around this, determine which configs to
# add and remove in order to succesfully build the project.

Generate build information from CHANGES.md 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).

Generate build information from CHANGES.md 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).

BUILD.gn: Fix file for use with Fuchsia platform build. In order to upgrade the version of glslang used by the Fuchsia platform source tree, BUILD.gn needs to be slightly modified to care about the case where it is not used with the Chromium //build configuration: - Remove a new compiler warning to ensure proper compilation with -Werror (which is the default). - Add a build target for spirv-remap, which is used by Fuchsia at build time to optimize the precompiled shaders of some of its graphics libraries.

gn: Fix dawn tests in Chromium Dawn tests use shaderc, which assumes glslang has HLSL support. This change makes HLSL support also follow template arguments, and changes the target names such that glslang_sources will remain the "has all features" target and the new glslang_lib_sources would be what ANGLE would use.

Fix config issues and revert previous fixes for semi-colon issues This reverts commit 41261d95a417bb3a121c162154d441433705a237. This reverts commit 7c9accb6534d4cde050555b8091b434dc7e4d218. Instead of trying to work around all of the potential semicolon issues in glslang, making it conform to Chromium's style, mark the code explicitly as non-chromium in the BUILD.gn, so chromium doesn't attempt to enforce its style rules on glslang. Fixes #1931

Add new SpirvToolsDisassemble API interface + Improve Doc on existing API interface (#2442) * Add new SpirvToolsDisassemble API interface + Improve Doc on existing API interface (#2408) * Add more flexible SpirvToolsDisassemble interface to allow specifying spv_target_env for disassembly output. Improve documentation on existing SpirvToolsDisassemble interface. * Update pre-processor check - following existing ENABLE_OPT checks. * Fix not-found header paths for glslangValidator and glslangtests. * Add spirv_tools/include path where there is an ENABLE_OPT=1 in the BUILD.gn configuration.

BUILD.gn: Fix fuchsia build (#1944) The Fuchsia platform build and the Chromium one use a completely different set of configs to specify default warnings. The previous version of BUILD.gn worked with Chromium, but failed to build with Fuchsia. This CL fixes the issue by identifying said configs and reusing them consistently.
