[PATCH] D116277: [RISCV] Use vmv.x.s to build one element splat vector.

[Craig Topper via Phabricator via llvm-commits]

craig.topper added a comment.

Do you have a particular microarchitecture where this is a faster sequence?

Why only integer and not FP?



================
Comment at: llvm/lib/Target/RISCV/RISCVISelLowering.cpp:2233
+    ConstantSDNode *Const = dyn_cast<ConstantSDNode>(Scalar);
+    // If VL is 1 and the scalar value won't benefited from immediate, we could
+    // use vmv.s.x.
----------------
benefited->benefit
