2022-06-23Added basic syntax to mark and request function derivatives, as well as the ↵Sai Praveen Bangaru
framework for passes to process them. (#2297) * Added a decorator to mark functions for forward-mode differentiation * Fill out support for calls to non-decl values The existing compiler logic has a few places (semantic checking plus AST-to-IR lowering) where it assumes that function calls (`InvokeExpr`) are only ever made to expressions that resolve to a specific `Decl` (`DeclRefExpr`). This assumption allows semantic checking and lowering code to inspect things like the parameter list of an actual declaration, rather than just the type signature of the callee, and that infrastructure is used to support various features (e.g., default argument values on parameters). The AST and IR representations themselves have no matching requirement, and the places where the more general case of call expressions would need to be supported were relatively clear in the code. This change attempts to add suitable logic into each of those places. Note that this change does *not* surface any valid way to form input code that would cause these new code paths to be executed, so it is entirely possible that there are bugs in the logic as written here. The primary goal of this change is simply to get a sketch of the correct code checked in so that we have something to build on once we have language features that will require this support. * fixup: warnings-as-errors * Added parser logic for '__jvp(<fn-name>)' operator * Fixed issue with missing overload candidate item and added basic parsing test for the __jvp syntax * Added a blank JVP Auto-diff pass and a pass that replaces 'JVPDerivativeOf' calls with the differentiated function * Added a couple comments * Added parameter handling for the JVP pass Co-authored-by: Theresa Foley <tfoley@nvidia.com>

* Fixed Vulkan validation errors for incorrect layer counts and view types in Debug * Removed old (and empty) render-vk files; Ran premake.bat
2022-05-27Added NativeStringType (#2252)jsmall-nvidia
* #include an absolute path didn't work - because paths were taken to always be relative. * Use TerminatedUnownedStringSlice for literals in output C++. * Remove Escape/Unescape functions used in slang-token-reader.cpp Add target type of 'host-cpp' etc to map to the target types. * Fix some corner cases around string encoding. * Added unit test for string escaping. Fixed some assorted escaping bugs. * Updated test output. * Added decode test. * Stop using hex output, to get around 'greedy' aspect. Use octal instead.
2022-05-26Split render-vk.h/.cpp into a set of smaller files (#2244)lucy96chen
* Some preliminary work on splitting render-vk * render-vk split, tests currently crash on null reference * fixed circular include

2022-05-17Split render-d3d12.h/cpp into a set of smaller files (#2231)lucy96chen
* Split render-d3d12 into numerous smaller files to make the code easier to parse * Added all new D3D12 files created from splitting render-d3d12 * Fixed several uses of attachment still floating around; Changed resource-d3d12 and descriptor-heap-d3d12 to match naming conventions of new d3d12 implementation header files * Readded files with name changes because changing them from inside VS apparently results in them being treated as new files * Merged in externals changes from master * Small cleanup changes * Rerun CI Co-authored-by: Theresa Foley <10618364+tangent-vector@users.noreply.github.com>

2022-05-10Use IR pass to eliminate phi nodes (#2226)Theresa Foley
* Use IR pass to eliminate phi nodes "Phi nodes" are one of the key contrivances that makes SSA (Static Single Assignment) form work. Because SSA is so great for compiler IRs, we kind of need to deal with phi nodes, but they also get in the way because they don't have a direct analog in most lower-level machine ISAs or execution models, nor in most of the high-level languages a transpiler wants to emit. As a result a compiler like ours needs to be able to eliminate the phi nodes from a program as part of generating output code. (For any clever people noting that SPIR-V supports phi nodes directly: yes, it does. It doesn't need to and it probably *shouldn't*. Anybody involved in the decision-making knows my reasoning, and anybody else should feel free to ask me if they want the lecture. Anyway...) The basic idea of elimiating phi nodes is simple enough. We replace each phi node with a temporary variable. Uses of the phi use values loaded from the temporary. The operation of the phi itself (assigning a value based on the branch taken) amounts to an assignment into the temporary. Previously, the Slang compiler dealt with phi nodes very late in the process of generating code: in the middle of emitting strings of source code in a high-level language like HLSL or GLSL. Doing the work that late in compilation has two big drawbacks: 1. Our ability to emit clean and/or optimal code is limited because we may not be able to make certain changes to the IR, or because we cannot make use of additional information like a dominator tree that might be available at other points in compilation. 2. Any other IR passes that relate to temporary variables won't be able to see the variables that we generate for phi nodes. This could raise issues with correctness (e.g., if we want to compute live-range information for *all* temporary variables), or performance (we have no way to run additional IR optimization passes after phis are eliminated). This change addresses these problems by making the elimination of phi nodes an explicit IR pass. Additional optimizations can easily be run after this pass (although we'd need to be careful not to run passes that could end up introducing new phis). The pass makes use of the information available to it to try to produce code that will emit to "clean" HLSL/GLSL. The core of the pass is in `slang-ir-eliminate-phis.cpp`, and is heavily commented, so I won't describe the approach in detail here. There are two related issues that came up, though: First, it turned out that our emit logic for local variables (`IRVar` instructions) wasn't using the function we'd defined named `emitVar()`. One worrying consequence of that oversight was that the `precise` modifier would impact generated HLSL/GLSL for variables that turned into SSA values (including phi nodes), but *not* for local variables that had not been SSA'd (or that had been SSA'd and then de-SSA'd). This change also fixes that bug; it is unclear how widespread the impact of the original issue might be. Second, generating explicit IR temporaries for phi nodes exposed a pre-existing bug in the `slang-ir-restructure-scoping` pass. That pass basically detects cases where we have an instruction `I` with a use `U` such that the use follows the rules of SSA form ("def dominates use," meaning `I` dominations `U`), but does not follow the more restrictive scoping rules of high-level-language output (where a value computed "inside" a loop is not automatically visible to code outside the loop just because it dominates that code). That pass did not correctly account for the case where `I` was a temporary variable. It seems that case could not arise before now because we didn't have any passes that would move `var`, `load`, or `store` operations out of the basic block they started in. The fix for that pass was relatively simple, and will make the whole thing more robust in case we add more aggressive optimizations later. * fixup: expected test output
