The issue has been benign as we recognize $unknown-apple-darwin as ELF insteadof rejecting it outrightly.

Another common case is: * a latch block * it has two successors, one is loop header, another is exit * it has more than one predecessorsIf it is below one of its predecessors P, only P can fall through to it, all other predecessors need a jump to it, and another conditional jump to loop header. If it is moved before loop header, all its predecessors jump to it, then fall through to loop header. So all its predecessors except P can reduce one taken branch.Differential Revision: https://reviews.llvm.org/D43256llvm-svn: 363471 List of files: /llvm-project/llvm/test/CodeGen/Hexagon/bug6757-endloop.ll Fri, 14 Jun 2019 23:08:59 +0000 Guozhi Wei <carrot@google.com> http://src.rcs.uwaterloo.ca:8080/source/history/llvm-project/llvm/test/CodeGen/Hexagon/bug6757-endloop.ll#046090db5330dd87e54a7b46ec34384dd3b43c31 [Hexagon] Add more lit testsllvm-svn: 327271 List of files: /llvm-project/llvm/test/CodeGen/Hexagon/bug6757-endloop.ll Mon, 12 Mar 2018 14:01:28 +0000 Krzysztof Parzyszek <kparzysz@codeaurora.org>
