14 | // This test case checks if function arguments already have the correct value |
15 | // when breaking at the beginning of a function. Functions with the | |
16 | // #[no_stack_check] attribute have the same prologue as regular C functions | |
17 | // compiled with GCC or Clang and therefore are better handled by GDB. As a | |
18 | // consequence, and as opposed to regular Rust functions, we can set the | |
19 | // breakpoints via the function name (and don't have to fall back on using line | |
20 | // numbers). For LLDB this shouldn't make a difference because it can handle | |
21 | // both cases. | |
