[][src]Trait rustc_mir::dataflow::at_location::FlowsAtLocation

pub trait FlowsAtLocation {
    fn reset_to_entry_of(&mut self, bb: BasicBlock);
fn reset_to_exit_of(&mut self, bb: BasicBlock);

🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

A trait for "cartesian products" of multiple FlowAtLocation.

There's probably a way to auto-impl this, but I think it is cleaner to have manual visitor impls.

Required Methods

🔬 This is a nightly-only experimental API. (rustc_private)

Reset the state bitvector to represent the entry to block bb.

Reset the state bitvector to represent the exit of the terminator of block bb.

Important: In the case of a Call terminator, these effects do not include the result of storing the destination of the call, since that is edge-dependent (in other words, the effects don't apply to the unwind edge).

Build gen + kill sets for statement at loc.

Note that invoking this method alone does not change the curr_state -- you must invoke apply_local_effect afterwards.

Apply current gen + kill sets to flow_state.

(loc parameters can be ignored if desired by client. For the terminator, the stmt_idx will be the number of statements in the block.)
