Struct DependencyAnalyzer

pub struct DependencyAnalyzer<'inst> { /* private fields */ }

Analyzes the dependencies between instructions.

Implementations

impl<'inst> DependencyAnalyzer<'inst>

pub fn analyze(instructions: &'inst [Instruction]) -> Self

Analyze the dependencies between instructions in the specified function body.

Parameters

• instructions: The function body to analyze.

Returns

The populated dependency analyzer.

pub fn instructions(&self) -> &'inst [Instruction]

Answer the instructions being analyzed.

Returns

The requested instructions.

pub fn writers(&self) -> &HashMap<AddressingMode, BTreeSet<ProgramCounter>>

Answer the direct writers of registers and rolling records, indexed by target.

Returns

The requested map.

pub fn readers(&self) -> &HashMap<AddressingMode, BTreeSet<ProgramCounter>>

Answer the direct readers of registers and rolling records, indexed by source.

Returns

The requested map.

pub fn transitive_dependencies( &self, ) -> Ref<'_, HashMap<AddressingMode, BTreeSet<ProgramCounter>>>

Compute the transitive dependencies of registers and rolling records, as a map from registers to all instructions that contribute to them.

Returns

The requested map.

pub fn transitive_dependents( &self, ) -> Ref<'_, HashMap<AddressingMode, BTreeSet<ProgramCounter>>>

Compute the transitive dependents of registers and rolling records, as a map from registers to all instructions that consume from them.

Returns

The requested map.

impl<'inst> PartialEq for DependencyAnalyzer<'inst>

fn eq(&self, other: &DependencyAnalyzer<'inst>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
