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-check-type.cpp | 13 +++++++++++++ 1 file changed, 13 insertions(+) (limited to 'source/slang/slang-check-type.cpp') diff --git a/source/slang/slang-check-type.cpp b/source/slang/slang-check-type.cpp index d402dde03..6a8f802f7 100644 --- a/source/slang/slang-check-type.cpp +++ b/source/slang/slang-check-type.cpp @@ -320,6 +320,19 @@ namespace Slang getSink()->diagnose(typeExp.exp, Diagnostics::cannotDefinePtrTypeToManagedResource); } } + + // Differentiable type checking. + // TODO: This can be super slow.
