================
Comment at: llvm/lib/Target/RISCV/RISCVFrameLowering.cpp:1076
+  // Far branches over 20-bit offset require a spill slot for scratch register.
+  if (!isInt<20>(EstimateFunctionSizeInBytes(MF, *TII))) {
+    int FI = MFI.CreateStackObject(RegInfo->getSpillSize(*RC),
----------------
Can we make an API like `isFarBranch` or something like it? Other places can reuse it possibly.
