2023-01-30Overhauled reverse-mode control flow handling (#2608)Sai Praveen Bangaru
* Added switch-case support; fixed non-diff parameter transposition * Made region propagation much more robust. Partial loop unzip implementation * WIP: Added most loop handling code, and a test. Still untested * Added CFG Normalization pass + CFG Reversal Pass + Loop Unzipping + most loop transcription * Add single-iter-loop test. * proj files * removed comments * Update reverse-loop.slang * Removed out-of-date code * Disabled IR validation during constructSSA phase of normalizeCFG. constructSSA now reuses sharedBuilder * Moved normalizeCFG() call to prepareFuncForBackwardDiff()
