I am not sure if this even works or not, but no other tests have it in 
lowercase and neither should this one. In addition of course to it being an 
unrelated change.


================
Comment at: clang/test/CodeGen/builtins-ppc-vsx.c:1838
+// CHECK-LABEL: test_vector_cpsgn_float
+// CHECK: %6 = call <4 x float> @llvm.copysign.v4f32(<4 x float> %4, <4 x 
float> %5) 
+  vec_cpsgn(a, b);
----------------
The test case should not hard-code the virtual register names such as `%4, %5, 
%6`. Those should be set in the signature of the function and checked in the 
call instruction. I believe that vreg naming is different on non-assert builds 
which would make this fail right away on bots that build without asserts/debug.
