| | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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 <yonghe@outlook.com>

(#2303) * Added JVPTranscriber to handle differentiation of load, store, var, param and return instructions, as well as conversion of data and function types * Changed class names to be more in line with convention. Added correct type checking for __jvp() and verified that simple calls with only loads and stores are processed correctly * Added logic to differentiate basic arithmetic and literals inside IRConstruct and fixed the way parameters are differentiated Co-authored-by: Yong He <yonghe@outlook.com>
* Added basic syntax to mark and request function derivatives, as well as the ↵Sai Praveen Bangaru2022-06-23
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>
