+// This test case checks if function arguments already have the correct value
+// when breaking at the first line of the function, that is if the function
+// prologue has already been executed at the first line. Note that because of
+// the __morestack part of the prologue GDB incorrectly breaks at before the
+// arguments have been properly loaded when setting the breakpoint via the
+// function name.
