Create a new SwitchOp.

pub fn cases(&self, ctx: &Context) -> Vec<SwitchCase>

Get the operands to pass to the default destination.

Trait Implementations

impl BranchOpFoldInterface for SwitchOp

fn check_fold( &self, ctx: &Context, operands: &[Option<AttrObj>], ) -> Vec<Ptr<BasicBlock>>

Return the list of possible successor blocks given that operands contains Some(attr) for each operand known to be constant, where attr contains the known constant value.

fn fold_in_place( &self, _ctx: &mut Context, _ops: &[Option<AttrObj>], _rewriter: &mut dyn Rewriter, ) -> IRStatus

Given a slice operand_attrs corresponding to each operand, indicating a known compile time constant value for that operand (if any), attempts to fold the op in place using the provided rewriter. Assumes that rewriter is positioned just before the op to be folded.

impl BranchOpInterface for SwitchOp

fn successor_operands(&self, ctx: &Context, succ_idx: usize) -> Vec<Value>

Get a list of Values that are forwarded to the target block.

fn add_successor_operand( &self, ctx: &mut Context, succ_idx: usize, operand: Value, ) -> usize

Add a new operand to be forwarded to the given successor. The operand is appended after existing operands for the specified successor. Returns the index of the newly added operand among the operands forwarded to the successor. The returned index can be used to determine the corresponding target block argument index. Panics if succ_idx is invalid.

fn remove_successor_operand( &self, ctx: &mut Context, succ_idx: usize, opd_idx: usize, ) -> Value

Remove and return the operand at opd_idx among the operands forwarded to successor succ_idx. Panics if succ_idx or opd_idx is invalid.

fn clone(&self) -> Self
