From 1093218d6f0e114eb9fa52d60ca525bf9dd9f98a Mon Sep 17 00:00:00 2001 From: Sai Praveen Bangaru <31557731+saipraveenb25@users.noreply.github.com> Date: Thu, 20 Oct 2022 14:22:00 -0400 Subject: Modified the new type system to support generic differentiable types … (#2413) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * Modified the new type system to support generic differentiable types and added support for differentiating overloaded functions. * Changed a few asserts to release asserts to avoid unreferenced variable errors * Fixed a naming issue with TypeWitnessBreadcumb::Flavor::Decl * Added logic to avoid tracking differentiable types if the module does not use auto-diff or define differentiable types. * Moved the auto-diff passes to after the specialization step, added a more complex generics test * Added a generics stress test and fixed AST-side logic. IR side needs some more work * Added differential getter and setter logic, fixed multiple issues with DifferentiableTypeDictionary, added support for loops and conditions * Changed differential getters to use pointer types, added getter type checking * Fixed some bugs related to diff type registration and differential getters * Removed some superfluous code * Removed some more unused code. * Fixed an issue with witness substitution * Minor fix Co-authored-by: Yong He --- source/slang/slang-emit.cpp | 25 +++++++++++++++++++++++++ 1 file changed, 25 insertions(+) (limited to 'source/slang/slang-emit.cpp') diff --git a/source/slang/slang-emit.cpp b/source/slang/slang-emit.cpp index 4666e80d8..1ea54475e 100644 --- a/source/slang/slang-emit.cpp +++ b/source/slang/slang-emit.cpp @@ -10,6 +10,8 @@ #include "slang-ir-collect-global-uniforms.h" #include "slang-ir-cleanup-void.h" #include "slang-ir-dce.h" +#include "slang-ir-diff-call.h" +#include "slang-ir-diff-jvp.h" #include "slang-ir-dll-export.h" #include "slang-ir-dll-import.h" #include "slang-ir-eliminate-phis.h" @@ -365,6 +367,29 @@ Result linkAndOptimizeIR( lowerReinterpret(targetRequest, irModule, sink); validateIRModuleIfEnabled(codeGenContext, irModule); + + // Inline calls to any functions marked with [__unsafeInlineEarly] again, + // since we may be missing out cases prevented by the functions that we just specialzied. + performMandatoryEarlyInlining(irModule); + + dumpIRIfEnabled(codeGenContext, irModule, "BEFORE-AUTODIFF"); + + // Process higher-order calles to auto-diff passes. + // 1.
