Implementations

impl Ppc64Frame

pub fn aligned_frame_size(local_bytes: usize) -> usize

Total stack frame size (linkage + locals), 16-byte aligned.

pub fn calculate_stack_offset(slot: usize) -> i32

Calculate the stack offset for local slot n (0-based).

Slots start above the linkage area and grow upward in address (i.e., at higher positive offsets from the old sp stored as back-chain). In the prologue we subtract frame_size from r1, so slot n is at LOCALS_BASE + n*8 from the new r1.

pub fn generate_prologue<W: Write>( writer: &mut W, local_bytes: usize, ) -> Result<()>

Emit the function prologue.

Saves LR, creates the stack frame, stores callee-saved r14-r31 if needed (we don’t track that here, so we just save LR and update the back-chain).

pub fn generate_epilogue<W: Write>( writer: &mut W, local_bytes: usize, ) -> Result<()>

Emit the function epilogue and return.

pub fn generate_tail_epilogue<W: Write>( writer: &mut W, local_bytes: usize, ) -> Result<()>

Deallocate the frame and restore LR, then the caller must branch to the tail target (no blr — that would return to this function instead of tail-calling).
