[][src]Struct cranelift_codegen::binemit::RegDiversions

pub struct RegDiversions { /* fields omitted */ }

Keep track of diversions in an block.

Methods

impl RegDiversions[src]

pub fn new() -> Self[src]

Create a new empty diversion tracker.

pub fn clear(&mut self)[src]

Clear the content of the diversions, to reset the state of the compiler.

pub fn is_empty(&self) -> bool[src]

Are there any diversions?

pub fn diversion(&self, value: Value) -> Option<&Diversion>[src]

Get the current diversion of value, if any.

pub fn iter(&self) -> Iter<Value, Diversion>[src]

Get all current diversions.

pub fn get(&self, value: Value, locations: &ValueLocations) -> ValueLoc[src]

Get the current location for value. Fall back to the assignment map for non-diverted values

pub fn reg(&self, value: Value, locations: &ValueLocations) -> RegUnit[src]

Get the current register location for value, or panic if value isn't in a register.

pub fn stack(&self, value: Value, locations: &ValueLocations) -> StackSlot[src]

Get the current stack location for value, or panic if value isn't in a stack slot.

pub fn regmove(&mut self, value: Value, from: RegUnit, to: RegUnit)[src]

Record a register -> register move.

pub fn regspill(&mut self, value: Value, from: RegUnit, to: StackSlot)[src]

Record a register -> stack move.

pub fn regfill(&mut self, value: Value, from: StackSlot, to: RegUnit)[src]

Record a stack -> register move.

pub fn apply(&mut self, inst: &InstructionData)[src]

Apply the effect of inst.

If inst is a regmove, regfill, or regspill instruction, update the diversions to match.

pub fn remove(&mut self, value: Value) -> Option<ValueLoc>[src]

Drop any recorded move for value.

Returns the to location of the removed diversion.

pub fn at_block(&mut self, entry_diversions: &EntryRegDiversions, block: Block)[src]

Resets the state of the current diversions to the recorded diversions at the entry of the given block. The recoded diversions is available after coloring on func.entry_diversions field.

pub fn save_for_block(
    &mut self,
    entry_diversions: &mut EntryRegDiversions,
    target: Block
)
[src]

Copy the current state of the diversions, and save it for the entry of the block given as argument.

Note: This function can only be called once on a Block with a given entry_diversions argument, otherwise it would panic.

pub fn check_block_entry(
    &self,
    entry_diversions: &EntryRegDiversions,
    target: Block
) -> bool
[src]

Check that the recorded entry for a given block matches what is recorded in the entry_diversions.

pub fn display<'a, R: Into<Option<&'a RegInfo>>>(
    &'a self,
    regs: R
) -> DisplayDiversions<'a>
[src]

Return an object that can display the diversions.
