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()' 2022-06-30T23:24:24+00:00 Sai Praveen Bangaru 31557731+saipraveenb25@users.noreply.github.com 2022-06-30T23:24:24+00:00 urn:sha1:77af111867eb72f26b460c5925be47aa22c71556 * 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 * Replaced some SLANG_UNEXPECTED macro uses with diagnostics instead * Added work-list-based on-demand generation of derivative functions * Fixed up a couple of TODOs * Added attribute [__custom_jvp(f)] to assign a custom derivative function to a declaration * Added a test for CustomJVPAttribute on a redeclaration of an imported function * Moving arithmetic test to new folder * Moving arithmetic test to new folder (2) * Added missing test module * Fixed a minor note Co-authored-by: Yong He <yonghe@outlook.com>
