Struct llvm_ir_analysis::ControlDependenceGraph

pub struct ControlDependenceGraph<'m> { /* fields omitted */ }

The control dependence graph for a particular function. https://en.wikipedia.org/wiki/Data_dependency#Control_Dependency

To construct a ControlDependenceGraph, use FunctionAnalysis, which you can get from ModuleAnalysis.

Implementations

impl<'m> ControlDependenceGraph<'m>

pub fn get_imm_control_dependencies<'s>(
    &'s self,
    block: &'m Name
) -> impl Iterator<Item = &'m Name> + 's

Get the blocks that block has an immediate control dependency on.

pub fn get_control_dependencies<'s>(
    &'s self,
    block: &'m Name
) -> impl Iterator<Item = &'m Name> + 's

Get the blocks that block has a control dependency on (including transitively).

This is the block’s immediate control dependencies, along with all the control dependencies of those dependencies, and so on recursively.

pub fn get_imm_control_dependents<'s>(
    &'s self,
    block: &'m Name
) -> impl Iterator<Item = CFGNode<'m>> + 's

Get the blocks that have an immediate control dependency on block.

pub fn get_control_dependents<'s>(
    &'s self,
    block: &'m Name
) -> impl Iterator<Item = CFGNode<'m>> + 's

Get the blocks that have a control dependency on block (including transitively).

This is the block’s immediate control dependents, along with all the control dependents of those dependents, and so on recursively.

pub fn is_control_dependent(&self, block_a: &'m Name, block_b: &'m Name) -> bool

Does block_a have a control dependency on block_b?

pub fn entry(&self) -> &'m Name

Get the Name of the entry block for the function
