Skip instructions that don't have side-effects and aren't used by anything. * WIP: Handling unconditional control flow and multi-block functions * Support for unconditional multi-block functions * Added a dead code elimination step to the derivative pass * Changed name of 'hasNoSideEffects()' * Refactored variable names * Added initial IR defs for new type system * Added necessary logic for semantic checking * Overhauled type system to use builtin pair types and conform to the IDifferentiable interface * Automatically replace IRDifferentiablePairType to a custom IRStructType * Added generics handling by expanding the conformance context functionality and allowing for type parameters * Minor fix: early return in processPairTypes() * Minor fixes to differentiable resolution on generic types * Added new instructions for differential pairs. Basic tests work now. Looking into generic types. * Adjusted most tests to the new type system. OutType and InOutType are still not properly working. * Updated __jvp to produce both primal and differential output * Moved autodiff related declarations to diff.meta.slang * Refactored variable names * Added initial IR defs for new type system * Added necessary logic for semantic checking * Overhauled type system to use builtin pair types and conform to the IDifferentiable interface * Automatically replace IRDifferentiablePairType to a custom IRStructType * Added generics handling by expanding the conformance context functionality and allowing for type parameters * Minor fix: early return in processPairTypes() * Minor fixes to differentiable resolution on generic types * Added new instructions for differential pairs. Basic tests work now. Looking into generic types. * Adjusted most tests to the new type system. OutType and InOutType are still not properly working. * Updated __jvp to produce both primal and differential output * Moved autodiff related declarations to diff.meta.slang * Removed external changes * Cleanup the transcription logic: each case returns a pair of insts for the primal and differential computation. 2022-07-12T03:18:06+00:00 Sai Praveen Bangaru 31557731+saipraveenb25@users.noreply.github.com 2022-07-12T03:18:06+00:00 urn:sha1:b513d0deef521318ad943d820dd37029075a33c4 * Added support for differentiating calls to basic functions, as well as arithmetic on the float3 type * Added test expected result
