Comment at: llvm/test/Analysis/CostModel/AArch64/sve-intrinsics.ll:7
-; CHECK-NEXT: Cost Model: Found an estimated cost of 72 for instruction: %extract_fixed_from_scalable = call <16 x i32> @llvm.experimental.vector.extract.v16i32.nxv4i32(<vscale x 4 x i32> %v0, i64 0)
-; CHECK-NEXT: Cost Model: Found an estimated cost of 72 for instruction: %insert_fixed_into_scalable = call <vscale x 4 x i32> @llvm.experimental.vector.insert.nxv4i32.v16i32(<vscale x 4 x i32> %v0, <16 x i32> %v2, i64 0)
-; CHECK-NEXT: Cost Model: Found an estimated cost of 1 for instruction: %extract_scalable_from_scalable = call <vscale x 4 x i32> @llvm.experimental.vector.extract.nxv4i32.nxv16i32(<vscale x 16 x i32> %v1, i64 0)
----------------
I have just reran the script, but this is the only real change in this test.
