2021-02-19Add a chapter on target platforms (#1720)Tim Foley
* Add a chapter on target platforms The primary goals of this chapter are: * Make users aware of just how many different ways of handling things there are across targets. If a user leaves this chapter thinking "how in the world can you abstract over all these differences?", then we have done our job, because they are primed to understand why layout and parameter binding are **necessarily** complicated. * Help users to understand/recall the relevant capabilities and restrictions of the platforms they care about most. If somebody only cares about D3D12 and Vulkan, I want them to leave with a detailed understanding of how those two differ so they can understand the *specifics* of where the layout and parameter-binding algorithms have to treat those targets differently. All of this could conceptually be just a background section in the layout and parameter-binding chapter, but putting it off in its own chapter avoids that one taking forever to actually get where it is going. * Typos

2020-08-19Int64 atomic add RWByteAddressBuffer support (#1504)jsmall-nvidia
* 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 * WIP adding support for InterlockedAddFp32 * Upgrade slang-binaries to have new glslang. * Fix issues with Windows slang-glslang binaries, via update of slang-binaries used. * WIP - atomicAdd.

Use HLSL prelude to pass the path to nvapi Added -nv-api-path * Refactor around IncludeHandler and impl of IncludeSystem * slang-include-handler -> slang-include-system Have IncludeHandler/Impl defined in slang-preprocessor * Small comment improvements. * Document atomic float add addition in target-compatibility.md. * CUDA float atomic support on RWByteAddressBuffer. * Add atomic-float-byte-address-buffer-cross.slang * Removed inappropriate-once.slang - the test is no longer valid when a file is loaded and has a unique identity by default. A test could be made, but would require an API call to create the file (so no unique id). Improved handling of loadFile - uses uniqueId if has one. * Work around for testing target overlaps - to avoid exceptions on adding targets. Simplify PathInfo setup. Modify single-target-intrinsic.slang - it no longer failed because there were no longer multiple definitions for the same target. * Int64 atomic add RwByteAddressBuffer support. * Fix typo in stdlib for int atomic ByteAddressBuffer. * Small fixes to int64 atomic test.

2020-03-18First pass at a language reference (#1279)Tim Foley
* First pass at a language reference We already had the `language-guide.md` document under `docs/`, but this is an attempt to introduce a more full-featured reference to the Slang language and its features. Right now it is mostly focused on the syntax and what the language allows to be declared, and it is a little light on semantic details throughout (mostly relying on familiarity with C to explain the things that are left unsaid). Even so, this hopefully provides a starting point to continue adding more detail. * typos and other small fixes

* WIP: 64 literal diagnostic and truncation. * Improve how integer truncation is handled/supported. Added literal-int64.slang test. Set a suffix on all literals.
