[PATCH] D130543: [RISCV]Enable isIntDivCheap when attribute is minsize

[Wang Pengcheng via Phabricator via llvm-commits]

pcwang-thead added inline comments.


================
Comment at: llvm/lib/Target/RISCV/RISCVISelLowering.cpp:12530
+  // instruction, as it is usually smaller than the alternative sequence.
+  // TODO: Add vector division?
+  bool OptSize = Attr.hasFnAttr(Attribute::MinSize);
----------------
The reason why other targets make vector an exception is because there is no vector integer division as the comments said, so I think it is OK for RVV since there are vector integer divide instructions. While for P extension, it could be an exception.
