[PATCH] D121354: [SLP] Fix lookahead operand reordering for splat loads.

[Alexey Bataev via Phabricator via llvm-commits]

ABataev added inline comments.


================
Comment at: llvm/lib/Transforms/Vectorize/SLPVectorizer.cpp:1091
+    /// `ScoreSplat` because it takes only 1 instruction in x86 for a 2-lane
+    /// vector using `movddup (%reg), xmm0`.
+    static const int ScoreSplatLoads = 3;
----------------
Thos is target specific for x86. What about other targets?
