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

[Fraser Cormack via Phabricator via llvm-commits]

frasercrmck added inline comments.


================
Comment at: llvm/lib/Target/RISCV/RISCVISelLowering.cpp:2238
+    ConstantSDNode *Const = dyn_cast<ConstantSDNode>(Scalar);
+    // If VL is 1 and the scalar value won't benefit from immediate, we could
+    // use vmv.s.x.
----------------
I'm not sure what "benefit from immediate" is saying. Is this a workaround to keep immediate patterns like `vadd.vi` matching?
