[Craig Topper via Phabricator via llvm-commits]

================
Comment at: llvm/lib/Target/AArch64/AArch64LoopIdiomRecognize.cpp:282
+  if (!match(Header->getTerminator(),
+             m_Br(m_ICmp(Pred, m_Instruction(Index), m_Value(MaxLen)),
+                  m_BasicBlock(EndBB), m_BasicBlock(WhileBB))))
----------------
I think you want m_Specific(Index) instead of m_Instruction. m_Instruction will match any instruction and overwrite Index
