// 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.
// Therefore the setup here sets them using line numbers (so be careful when changing this file).
