+
+// This test case checks if function arguments already have the correct value when breaking at the
+// beginning of a function. Functions with the #[no_split_stack] attribute have the same prologue as
+// regular C functions compiled with GCC or Clang and therefore are better handled by GDB. As a
+// consequence, and as opposed to regular Rust functions, we can set the breakpoints via the
+// function name (and don't have to fall back on using line numbers).
