Bjorn Pettersson	9033ba7995	[NewPM] Rename 'unswitch' to 'simple-loop-unswitch' in PassRegistry ... It is confusing to have two ways of specifying the same pass ('simple-loop-unswitch' and 'unswitch'). This patch replaces 'unswitch' by 'simple-loop-unswitch' to get a unique identifier. Using 'simple-loop-unswitch' instead of 'unswitch' also has the advantage of matching how the pass is named in DEBUG_TYPE etc. So this makes it a bit more consistent how we refer to the pass in options such as -passes, -print-after and -debug-only.

Arthur Eubanks	f22bd23bc0	[SimpleLoopUnswitch] Don't non-trivially unswitch loops that are unsafe to clone ... Non-trivial unswitching can clone loops. The legacy -loop-unswitch pass also checks for this. Fixes PR49085. Reviewed By: asbirlea Differential Revision: https://reviews.llvm.org/D96288	2021-02-08 13:19:24 -08:00
