Struct libafl_cc::cfg::ControlFlowGraph

pub struct ControlFlowGraph<T>where
    T: HasWeight<T>,{ /* private fields */ }

An LLVM style control flow graph. Note: This does not track across functions.

Implementations

impl<T> ControlFlowGraph<T>where T: HasWeight<T>,

pub fn new() -> Self

Inserts an edge into CFG.

impl<T> ControlFlowGraph<T>where T: HasWeight<T>,

pub fn from_file(file_name: &str) -> ControlFlowGraph<T>

Load a CFG from a dump file generated by AFLCoverage pass.

pub fn from_content(content: &str) -> ControlFlowGraph<T>

Load a CFG from string generated by AFLCoverage pass.

pub fn get_edge(&self, xored_loc: usize) -> Option<&CfgEdge<T>>

Get the edge at the index of the coverage map AFL inserts to.

pub fn get_edge_mut(&mut self, xored_loc: usize) -> Option<&mut CfgEdge<T>>

Get the mutable edge at the index of the coverage map AFL inserts to.

pub fn get_entry(&self, func_name: &str) -> Option<&EntryBasicBlockInfo>

Get entry basic block information of a function.

pub fn get_entry_mut( &mut self, func_name: &str ) -> Option<&mut EntryBasicBlockInfo>

Get mutable entry basic block information of a function.

pub fn calculate_distances_to_all_edges( &self, start: usize ) -> HashMap<usize, u32>

Calculate shortest distance from start edge to all other edges in the function containing such start.

Unreachable edges from start would not be inserted in the returned hash map.
