+; This testcase checks to see if CodeExtractor properly inherits
+;   target specific attributes for the extracted function. This can
+;   cause certain instructions that depend on the attributes to not
+;   be lowered. Like in this test where we try to 'select' the blendvps
+;   intrinsic on x86 that requires the +sse4.1 target feature.
