Struct MemorySSA

pub struct MemorySSA<'a> {
    pub effect_analysis: &'a EffectAnalysis,
    /* private fields */
}

Expand description

MemorySSA analyzer. Reference: https://llvm.org/docs/MemorySSA.html My version is different by analyzing the effect of function calls.

Implementations§

Source §

impl<'a> MemorySSA<'a>

Source

pub fn new(program: &Program, effect_analysis: &'a EffectAnalysis) -> Self

Build MemorySSA for program.

Source

pub fn get_inst_node(&self, inst: InstPtr) -> Option<NodePtr>

Get node from instruction.

Source

pub fn get_block_node(&self, bb: BBPtr) -> Option<NodePtr>

Get node from block.

Source

pub fn get_node_block(&self, node: NodePtr) -> Option<BBPtr>

Get block from node.

Source

pub fn get_user(&self, node: NodePtr) -> HashSet<NodePtr>

Get all users of a node.

Source

pub fn predict_read( &self, src: NodePtr, dst: InstPtr, func: FunPtr, ) -> Result<Option<Operand>>

Assume src writes memory, predict content read from dst.

Source

pub fn dump(&self) -> String

Dump MemorySSA result to string.

Source

pub fn dump_node(&self, node: NodePtr) -> String

Dump a node to string.

Source

pub fn remove_node(&mut self, node: NodePtr)

Remove a node, update use-def chain.

§Panics

Do not remove used phi node or entry node with this function!
