[PATCH] D108108: [LoopPeel] Allow peeling with multiple unreachable-terminated exit blocks.

[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri added inline comments.


================
Comment at: llvm/lib/Transforms/Utils/LoopPeel.cpp:103-109
+  L->getUniqueNonLatchExitBlocks(Exits);
+  // The latch must either be the only exiting block or all non-latch exit
+  // blocks are either have an deopt or unreachable terminator.
+  return all_of(Exits, [](const BasicBlock *BB) {
+    return BB->getTerminatingDeoptimizeCall() ||
+           isa<UnreachableInst>(BB->getTerminator());
+  });
----------------
(As per brief disscussion in IRC) since this is about loop reentry, how about something like this then?
