Change

rucc_opt::live

Struct Change 

Source 
pub struct Change {
    pub gone: Vec<Value>,
    pub arrived: Vec<Value>,
}
Expand description

What one instruction does to the live set, seen walking the block backwards.

Both lists hold each value once, because they record the bits that moved rather than the names the instruction wrote: a value an instruction names twice is one bit and arrives once.

Fields§

§gone: Vec<Value>

Values the instruction defines, which are live after it and not before it.

§arrived: Vec<Value>

Values it names, which are live before it and were not after it.
