[PATCH] D107711: [DAGCombiner] Add target hook function to decide folding (mul (add x, c1), c2)

[Luís Marques via Phabricator via llvm-commits]

================
Comment at: llvm/lib/Target/RISCV/RISCVISelLowering.cpp:9088
+  // Let the DAGCombiner decide for larger types.
+  if (Subtarget.getXLen() < VT.getScalarSizeInBits())
+    return true;
----------------
Nit: IMO, it would be more intuitive to compare the other way around, swapping the operands and changing the condition to `>=`.
