+// Tests are functions which accept no parameters and have no return values.
+// The testing code should not perform an explicit return once completed. For
+// example to test the mov immediate instruction a very simple test would be:
+//
+// TEST(mov_x0_one) {
+// SETUP();
+//
+// START();
+// __ mov(x0, Operand(1));
+// END();
+//
+// RUN();
+//
+// CHECK_EQUAL_64(1, x0);
+//
+// TEARDOWN();
+// }
+//
+// Within a START ... END block all registers but sp can be modified. sp has to
+// be explicitly saved/restored. The END() macro replaces the function return
+// so it may appear multiple times in a test if the test has multiple exit
+// points.
+//
+// Once the test has been run all integer and floating point registers as well
+// as flags are accessible through a RegisterDump instance, see
+// utils-arm64.cc for more info on RegisterDump.
+//
+// We provide some helper assert to handle common cases:
+//
+// CHECK_EQUAL_32(int32_t, int_32t)
+// CHECK_EQUAL_FP32(float, float)
+// CHECK_EQUAL_32(int32_t, W register)

+// CHECK_EQUAL_64(int64_t, X register)
+// CHECK_EQUAL_64(X register, X register)
+// CHECK_EQUAL_FP64(double, D register)
+//
+// e.g. CHECK_EQUAL_64(0.5, d30);
+//
