[PATCH] D82416: [SVE] Make Constant::getSplatValue work for scalable vector splats

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

It looks like this affects a bunch of the pattern-matchers in PatternMatch.h; for example, m_APInt.  Is that right?



================
Comment at: llvm/lib/IR/Constants.cpp:1534
+      Constant *SplatVal = IElt->getOperand(1);
+      ConstantInt *Index = cast<ConstantInt>(IElt->getOperand(2));
+
----------------
I don't see any reason the index here would be a ConstantInt, in general.  (I mean, the result here would be pretty silly if it wasn't, but nothing is actually enforcing it.)
