2023-02-21Added support for simple while loops (#2667)Sai Praveen Bangaru
* Added support for simple while loops * Fix support for while loops by changing logic to grab the loop update block
2023-02-21Take into account the optimization level requested in TargetDesc (#2649)Ellie Hermaszewska
* Take into account the optimization level requested in TargetDesc Combines conflicting optimization levels by taking the maximum between them; as such they now each represent the lower bound on the eventual optimization level. Most of the changes are making this clear by s/optimizationLevel/minimumOptimizationLevel Closes https://github.com/shader-slang/slang/issues/2324 * Remove optimization level from TargetDesc
2023-02-20Miscellaneous backward autodiff fixes. (#2665)Yong He
* Fix differentiable type registration * Fix use of non-differentiable return value in a differentiable func. * Fix use of primal inst that does not dominate the diff block. * Fix primal inst hoisting, and add missing type legalization logic. * Make `detach` defined on all differentiable T. --------- Co-authored-by: Yong He <yhe@nvidia.com>

* WIP: Remove all legacy type checking * Fixed issue with user-defined backward derivatives not bypassing the AD process --------- Co-authored-by: Yong He <yonghe@outlook.com>
2023-02-17AD: Remove the original loop condition upon inversion (#2661)Sai Praveen Bangaru
* Remove the original condition upon loop inversion (it's redundant, and causes out-of-bounds accesses) * minor fix (also removed the first loop check skip) * Cleanup unused insts * minor comment fix
2023-02-17Fixed crash when lowering IR for no_diff struct member. (#2658)Yong He
* Fixed crash when lowering IR for no_diff struct member. * Improve `setInsertBeforeOrdinaryInst` and `setInsertAfterOrdinaryInst`. --------- Co-authored-by: Yong He <yhe@nvidia.com>
2023-02-17Cleaned up legacy differential type handling + type casting bugfixes (#2660)Sai Praveen Bangaru
2023-02-17Proper reverse-mode loop handling with splitting + inversion steps (#2656)Sai Praveen Bangaru
* Halfway to loop inversion * More progress towards proper loop inversion * More progress towards inverse insts. Only thing left is adding `counter>=0` at the right place * More fixes for inversion step. * Lots more fixes, added primal inst 'hoisting' mechanism as the central method that ensures primal values are placed in the right spot * Loop inversion is now functional * Cleaned up commented code * rename diffCounterVar -> diffCounterParam * minor update * removed some comments and commented code * Switch `IRBuilder(sharedIRBuilder)` to `IRBuilder(moduleInst)`
2023-02-16Remove `SharedIRBuilder`. (#2657)Yong He

2023-02-11Comment call to vkCreateInstance with a potential pitfall (#2642)Ellie Hermaszewska
