/// Rewrite all stack memory accesses
|
|
///
|
|
/// This pass changes the base address of stack memory access to either:
|
|
///
|
|
/// * The stack frame of the function (allocated by the `revng_stack_frame`
|
|
/// function).
|
|
/// * The stack arguments of a call site (allocated by the
|
|
/// `revng_call_stack_arguments` function), which is then passed in as the
|
|
/// last argument of the function.
|
|
/// * The (newly introduced) last argument of the function representing the
|
|
/// stack arguments.
|
|
///
|
|
/// After this pass, all stack accesses have positive offsets and
|
|
/// `_init_local_sp` is dropped entirely.
