Dan Zheng	07f632acaa	[AutoDiff] NFC: document test suite. (#35194) ... Add README files explaining the differentiable programming test suite. Add lit.local.cfg files so individual tests do not need to add `REQUIRES: asserts` in these directories: - test/AutoDiff/compiler_crashers - test/AutoDiff/compiler_crashers_fixed Motivation: it is important for compiler crasher tests to require assertions enabled, because many of these tests crash on compiler assertions.	2020-12-23 07:19:19 -05:00
Dan Zheng	2cf7d63a5e	[AutoDiff] Fix ownership error in VJPCloner::visitApplyInst. (#35003) ... Change the following code pattern: ``` %x1 = convert_function %x0 : $@differentiable (...) -> ... %x2 = begin_borrow %x1 ... // use %x2 %x3 = end_borrow %x2 destroy_value %x0 ``` To the following: ``` %x1 = begin_borrow %x0 : $@differentiable (...) -> ... %x2 = convert_function %x0 ... // use %x2 %x3 = end_borrow %x1 destroy_value %x0 ``` Resolves SR-13933: "multiple consuming users" ownership error caused by `VJPCloner::visitApply` related to `@differentiable`-function-typed callees. Also upstream test/AutoDiff/SILOptimizer/generics.swift from tensorflow branch.	2020-12-08 19:48:31 -05:00
