Struct MachTextSectionBuilder

pub struct MachTextSectionBuilder<I: VCodeInst> { /* private fields */ }

Implementation of the TextSectionBuilder trait backed by MachBuffer.

Note that MachBuffer was primarily written for intra-function references of jumps between basic blocks, but it’s also quite usable for entire text sections and resolving references between functions themselves. This builder interprets “blocks” as labeled functions for the purposes of resolving labels internally in the buffer.

Implementations

impl<I: VCodeInst> MachTextSectionBuilder<I>

pub fn new(num_funcs: usize) -> MachTextSectionBuilder<I>

Creates a new text section builder which will have num_funcs functions pushed into it.

Trait Implementations

impl<I: VCodeInst> TextSectionBuilder for MachTextSectionBuilder<I>

fn append( &mut self, labeled: bool, func: &[u8], align: u32, ctrl_plane: &mut ControlPlane, ) -> u64

Appends data to the text section with the align specified.

fn resolve_reloc( &mut self, offset: u64, reloc: Reloc, addend: Addend, target: usize, ) -> bool

Attempts to resolve a relocation for this function.

fn force_veneers(&mut self)

A debug-only option which is used to for

fn write(&mut self, offset: u64, data: &[u8])

Write the data provided at offset, for example when resolving a relocation.

fn finish(&mut self, ctrl_plane: &mut ControlPlane) -> Vec<u8>

Completes this text section, filling out any final details, and returns the bytes of the text section.
