[PATCH] D118026: [RISCV] Improve the condition of hasRVVFrameObject.

[Craig Topper via Phabricator via llvm-commits]

craig.topper added inline comments.


================
Comment at: llvm/lib/Target/RISCV/RISCVFrameLowering.cpp:976
+      for (const auto &MO : MI.uses())
+        if (MO.isReg() && MO.getReg() == RISCV::VL)
+          return true;
----------------
Is it possible to write a function that contains nothing but whole register loads/stores/moves such that no instruction access VL but needs to spill a register?
