[PATCH] D103458: [SLP]Improve gathering of scalar elements.

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added inline comments.


================
Comment at: llvm/test/Transforms/SLPVectorizer/X86/ordering-bug.ll:33
+; CHECK-NEXT:    [[TMP10:%.*]] = insertelement <2 x i64> poison, i64 [[TMP9]], i32 1
+; CHECK-NEXT:    [[TMP11:%.*]] = insertelement <2 x i64> [[TMP10]], i64 [[AND0_TMP]], i32 0
 ; CHECK-NEXT:    [[TMP12:%.*]] = and <2 x i64> [[TMP11]], [[TMP7]]
----------------
This is annoying - SelectionDAG wastes a lot of time reordering insertelement chains patterns into ascending order to try and match buildvector patterns - can we avoid it?
