Upgrade to Glslang 11.0.0 (#1466)

2020-07-31T20:31:30+00:00

* Fix premake5.lua so it uses the new path needed for OpenCLDebugInfo100.h * Keep including the includes directory. * Added the spirv-tools-generated files. * We don't need to include the spirv/unified1 path because the files needed are actually in the spirv-tools-generated folder. * Put the build_info.h glslang generated files in external/glslang-generated. Alter premake5.lua to pick up that header. * First pass at documenting how to build glslang and spirv-tools. * Improved glsl/spir-v tools README.md * Added revision.h * Change how gResources is calculated. Update about revision.h * Update docs a little. * Split out spirv-tools into a separate project for building glslang. This was not necessary on linux, but *is* necessary on windows, because there is a file disassemble.cpp in spirv-tools and in glslang, and this leads to VS choosing only one. With the separate library, the problem is resolved. * Fix direct-spirv-emit output. * Update to latest version of spirv headers and spirv-tools. * Upgrade submodule version of glslang in external. * Add fPIC to build options of slang-spirv-tools * Upgrade slang-binaries to have new glslang. * Fix issues with Windows slang-glslang binaries, via update of slang-binaries used. * Small improvements to glslang building process documentation.

Initial work on direct emission of SPIR-V (#1118)

2019-11-14T21:11:07+00:00

* Initial work on direct emission of SPIR-V This change adds a first vertical slice of support for emitting SPIR-V code directly from the Slang IR, instead of generating it indirectly via GLSL. This work isn't usable for anything valuable right now; the goal is just to get something checked in that we can incrementally extend over time. When invoking `slangc`, the `-emit-spirv-directly` option can be used to turn on the new code path. I have not bothered to add an equivalent API option, because this flag is only intended to be used for testing in the immediate future. The existing `emitEntryPoint()` function has become `emitEntryPointSource()` to more accurately reflect its role in a world where we can also emit entry points to a binary format. Much of the logic that was inside `emitEntryPoint()` had to do with linking and then optimizing/transforming Slang IR code to get it ready for emission on a particular target. This logic has been factored into a new `linkAndOptimizeIR()` function that can be shared between the path that emits source and the new one that emits SPIR-V. The meat of the change is then the `emitSPIRVFromIR()` function in `slang-emit-spirv.cpp`, which is called *after* all the optimizations and transformations have been applied to the Slang IR to get it ready. Rather than repeat myself here, I will try to make the comments in `slang-emit-spirv.cpp` usable as documentation of the approach being taken. Smaller notes: * I've included a test case that compares `slangc` output directly to expected SPIR-V. This is perhaps not an ideal plan for how to test SPIR-V emission going forward, but it suffices for now. * The `external/` directory needed to be added to the include dirs for the `slang` project so that the new code can depend on the SPIR-V header. * In `slang-ir-link`, the direct SPIR-V generation path means that we now link with a target of SPIR-V instead of GLSL. In principle this can be used to ensure that appropriate variants of intrinsics are selected based on the knowledge that we are emitting SPIR-V. In practice, that isn't being used at all. * Fixup: path for SPIR-V headers While working on this PR I used a copy of `spirv.h` that I placed into the repository tree manually, but since I started the work we ended up with SPIR-V headers in our tree anyway, albeit at a different path. This change tries to fix things up so that my code uses the headers that were already placed in the repository. * fixup; 64-bit build issue * fixup: typo fixes based on review
