[PATCH] D63629: [JumpThreading][PR42085] Do not fold conditional terminators of loop headers

[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri added a comment.

> Folding conditional terminator instructions for basic blocks that are also loop headers can cause miscompiled code emitted from JumpThreading.

Please can you write a more detailed explanation of the problem in the patch description.
"cause miscompiled code emitted" is vague.
