Struct FnAliasPairs 

pub struct FnAliasPairs {
    arg_size: usize,
    alias_set: HashSet<AliasPair>,
}

To store the alias relationships among arguments and return values. Each function may have multiple return instructions, leading to different RetAlias.

Fields

arg_size: usize

alias_set: HashSet<AliasPair>

Implementations

impl FnAliasPairs

pub fn new(arg_size: usize) -> FnAliasPairs

pub fn arg_size(&self) -> usize

pub fn aliases(&self) -> &HashSet<AliasPair>

pub fn add_alias(&mut self, alias: AliasPair)

pub fn len(&self) -> usize

pub fn sort_alias_index(&mut self)

pub fn compress_fields(&mut self)

Compress field paths: truncate each side’s field list to its first element. This matches the old MoP alias analysis behaviour where deeply nested fields like 0.0.0.0 are shortened to 0.0.
