+description: >
+  Set values from different instances using the different buffer and same
+  constructor. srcBuffer values are cached.
+info: |
+  22.2.3.23.2 %TypedArray%.prototype.set(typedArray [ , offset ] )
+
+  1. Assert: typedArray has a [[TypedArrayName]] internal slot. If it does not,
+  the definition in 22.2.3.23.1 applies.
+  ...
+  23. If SameValue(srcBuffer, targetBuffer) is true, then
+    ...
+  24. Else, let srcByteIndex be srcByteOffset.
+  ...
+  27. If SameValue(srcType, targetType) is true, then,
+    a. NOTE: If srcType and targetType are the same, the transfer must be
+    performed in a manner that preserves the bit-level encoding of the source
+    data.
+    b. Repeat, while targetByteIndex < limit
+      i. Let value be GetValueFromBuffer(srcBuffer, srcByteIndex, "Uint8").
+      ii. Perform SetValueInBuffer(targetBuffer, targetByteIndex, "Uint8",
+      value).
+  ...
+  29. Return undefined.
