2022-02-03Fixed naming conflicts in heterogeneous-hello-world (#2114)David Siher
* Fixed naming conflicts in heterogeneous-hello-world Added 3 new modifiers (`__unmangled`, `__exportDirectly`, `__externLib`) `__unmangled` causes mangleName() to return the normal name of the decl. `__exportDirectly` changes parent decl name concatenation behavior to use "::" instead of "." (for Name Hint) and emits the name hint when it exists, otherwise it emits the mangled name. `__externLib` stops Slang from emitting the corresponding struct. Also made necessary changes to heterogeneous-hello-world so that this new functionality is shown off. * Undo unintentional formatting changes Co-authored-by: Yong He <yonghe@outlook.com>

2021-03-12Add a CPU renderer implementation (#1750)Tim Foley
* Add a CPU renderer implementation This change adds a CPU back-end to `gfx` and ensures that most of our existing CPU tests pass when using it. Detailed notes: * Most of the CPU renderer implementation is copy-pasted from the CUDA case, so they share a lot of similar logic * The main addition to the CPU renderer is a semi-complete implementation of host-memory textures. The logic here handles all the main shapes (Buffer, 1D, 2D, 3D, Cube) and all the currently-supported `Format`s that are sample-able as-is (no D24S8). The implementation is not intended to be fast, and it currently only does nearest-neighbor sampling, but otherwise it tries to avoid cutting too many corners and should be ar reasonable starting point for a more complete (but not performance-oriented) implementation. * Refactored the CPU prelude `IRWTexture` interface to inherit from `ITexture`, since in most cases a single type will end up implementing both. It might be worth it to collapse it all down to a single interface later. * Changed the CPU prelude `ITexture`/`IRWTexture` interface so that it takes both a pointer *and* a size for output arguments. This change seems necessary to allow a shader variable declared as a `Texture2D<float>` to fetch a single `float` when the underlying texture might be using RGBA32F. * Added to the `IComponentType` public API so that we can query a "host callable" for an entry point and not just a binary. * Turned off the `-shaderobj` flag on two tests that weren't yet compatible with shader objects but still had the flag left in on the path (since previously the CPU path always used the non-`gfx` non-shader-object logic anyway) * Disabled one test (`dynamic-dispatch-11`) that relied on the `ConstantBuffer<IInterface>` idiom that we know we are planning to chagne soon anyway. * Made a few changes to the CUDA path to bring it into line with what I added for the CPU path. These were mostly bug fixes around indexing logic for sub-objects and resources. * fixup

2020-10-05Small fixes for CUDA code emit (#1564)Tim Foley
* Small fixes for CUDA code emit * Add a CUDA translation to `GroupMemoryBarrierWithWaveSync()`. We map this to `__syncwarp()` for CUDA (with no mask, implying a full-warp sync). * Consistently use `SLANG_PRELUDE_ASSERT` for assertions introduced in code emit (rather than just using the bare `assert(...)` function, which is not included by our CUDA prelude by default) * Add a new `SLANG_CUDA_STRUCTURED_BUFFER_NO_COUNT` flag to the CUDA prelude that allows the `count` field to be omitted from `(RW)StructuredBuffer<T>`. This is a bit of a hacky because the computed layouts will still assume the `count` field is present, but this feature is required by at least one client application for now. A better long-term fix will take more time to design and implement. * fixup: CUDA prelude code fix for pedantic compilers Co-authored-by: Tim Foley <tim.foley.is@gmail.com> Co-authored-by: Yong He <yonghe@outlook.com>

2020-09-23Simplify workflow when using NVAPI (#1556)Tim Foley
In some cases, functionality is available as either a GLSL extension for Vulkan/SPIR-V, or through the NVAPI system for D3D. This situation creates complications because while GLSL extensions are generally all supported by the open-source glslang compiler (which we can bundle and ship), NVAPI operations are exposed through a specific header (`nvHLSLExtns.h`) that ships as part of the NVAPI SDK. When a user wants to explicitly use NVAPI-provided operations in their shader code, there are no major complications for Slang; the user sets up their include paths, `#include`s the relevant header, calls functions in it, and lets Slang deal with the details of compilation. The challenge for Slang arises when we want to provide a cross-platform interface in our standard library (e.g., the `RWByteAddressBuffer.InterlockedAddF32` method that was recently added) that uses either a GLSL extension (when compiling for Vulkan/SPIR-V) or an NVAPI (when compiling to DXBC or DXIL). In that case, the code *generated* by Slang now has a dependency on NVAPI, and we need to somehow emit a `#include` directive that pulls it in when invoking fxc or dxc. Because we do not (and seemingly cannot) bundle the NVAPI header with the compiler, we have to rely on ther user to have it available and to somehow communicate to Slang where it is. Exposing portable routines that sometimes use NVAPI currently creates two main challenges: 1. The user is forced to interact with the "prelude" mechanism in the compiler, which allows the programmer to define code in a given target language that gets prepended to the Slang-generated code. While the prelude mechanism is powerful, it is also hard for users to integrate into their workflow, and our experience so far is that users want something that Just Works. 2. If the user writes code that uses some of our abstract operations that layer on NVAPI *and* they also want to use NVAPI explicitly, they end up with two copies of the NVAPI header (one included by the Slang front-end, and another included by the downstream fxc/dxc compiler). This puts the user in the situation of (a) having to ensure that they set the defines like `NV_SHADER_EXTN_SLOT` consistently both when invoking Slang and when adding their prelude, and (b) even if they do make the definitions consistent, they run into the problem that fxc/dxc complain about overlapping register bindings on the two copies of the `g_NvidiaExt` global shader paraemter that the NVAPI header declares. This change attempts to resolve both issues by adding a lot of "do what I mean" logic to the compiler to try to ease things in the common case. In particular: 1. The user no longer needs to use the "prelude" mechanism when using NVAPI. The compiler now embeds a default prelude for HLSL output, which will `#include` the NVAPI header if and only if the generated code needs NVAPI access because of portable standard library routines that were used. 2. The user can mix-and-match explicit NVAPI use and stdlib functions that compile to use NVAPI. The register/space to be used by NVAPI when included via prelude is now set based on whatever the user set via the preprocessor so that it should automatically be consistent between both cases. Furthermore, the code we emit for the declaration of `g_NvidiaExt` when compiling explicit NVAPI use is set up to be conditional, so that it is skipped in the case where the prelude will pull in its own declaration of that parameter. The way all this is achieved involves a lot of moving pieces: * We now have an HLSL prelude, which mostly just serves to `#include "nvHLSLExtns.h"` in the case where NVAPI support is needed downstream. * Standard library operations that require NVAPI for their implementation on HLSL include a new `[__requiresNVAPI]` attribute. * The preprocessor has been extended so that after tokenizing an input file it looks up the NVAPI-relevant macros in the resulting environment, and if they are set it attached a modifier (`NVAPISlotModifier1) to the AST `ModuleDecl` that is based on their values. Logic is added to detect if multiple input files specify values for the macros in ways that conflict. * The semantic checking step is extended so that it detects the "magic" NVAPI declarations (the `g_NvidiaExt` paramter and the `NvShaderExtnStruct` type that it uses) and attaches a modifier to them so that they can be identified as such in later steps. * Parameter binding is extended to collect a list of the AST modifiers that reflect NVAPI binding, and to reserve the relevant register(s) so that ordinary user-defined parameters cannot conflict with them. * IR lowering translates the three new AST modifiers related to NVAPI over to IR equivalents. * IR linking is extended to make sure that it clones any `IRNVAPISlotDecoration`s attached to the input modules. The pass intentionally does not care where the modifiers came from; it just collects them all and leaves it to downstream code to sort out what they mean. * Emit logic is extended to have a notion of "prelude directives" which are preprocessor directives that should come *before* the prelude in the generated code, because they can impact the way that the prelude compiles. This is done so that we don't have to introduce ad hoc logic for each downstream compiler to set any relevant `-D` flags (e.g., both fxc and dxc would need to duplicate such logic for NVAPI support). * The HLSL source emitter is extended to track whether it emits any operations that require NVAPI support. * The HLSL source emitter is extended to emit prelude directives based on whether NVAPI is needed and, if it is, to also set the register and space that NVAPI should use based on what was stored in the decoration(s) on the IR module. * The HLSL source emitter is extended so that it detects global instructions that represent "magic" NVAPI constructs , and emit them as conditional definitions so that they are skipped when NVAPI is included via the prelude. * The handling of requires capabilities during emit logic was cleaned up a bit so that more logic is shared across targets, and also so that the same logic is used both when emitting a function declaration/definition and when emitting a call to an instrinsic function (which won't get declared/defined).
2020-09-16Fix some issues around dim3 for CUDA (#1544)Tim Foley
The logic we use to compute `SV_DispatchThreadID` and friends for CUDA makes use of the `gridDim` and `blockDim` built-in variables in CUDA. These variables have type `dim3` which is similar to `uint3` but is considered a distinct type for some reason. The logic for computing the `SV`s currently pretends that `gridDim` and `blockDim` are `uint3`s, and this means that the code they emit doesn't always compile cleanly (although it does in our existing test cases...). This change adds a few overloads that work on `dim3` to the CUDA prelude and that seem to make the code we emit work again. Note: This change should be seen as a somewhat hacky quick fix rather than a real resolution to the underlying issue. It is probably better if we emit code that replaces uses of `gridDim` with `uint3(gridDim.x, gridDim.y, gridDim.z)` instead, to ensure that we get the typing correct, even if the result looks less idiomatic.
2020-08-18Support for float atomics on RWByteAddressBuffer (#1502)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. This solution can't work as we can't do (float*) in glsl. * WIP on atomic float ops. * Added checking for multiple decls that takes into account __target_intrinsic and __specialized_for_target. First pass impl of atomic add on float for glsl. * Split __atomicAdd so extensions are applied appropriately. * Made Dxc/Fxc support includes. 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. Co-authored-by: Tim Foley <tfoleyNV@users.noreply.github.com>
