[PATCH] D97961: [Cost]Caonicalize the cost for logical or/and reductions.

[Alexey Bataev via Phabricator via llvm-commits]

ABataev added inline comments.


================
Comment at: llvm/include/llvm/CodeGen/BasicTTIImpl.h:1909
+      // FIXME: some targets did not implement cost for vector-to-int bitcast.
+      return getCastInstrCost(Instruction::BitCast, ValTy, Ty,
+                              TTI::CastContextHint::None, CostKind) +
----------------
SystemZ cost model does not implement vector-to-int bitcast and crashes. That's why have to use `Base::getCastInstrCost()` here rather than `thisT()->getCastInstrCost()`
