🔬 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 streamlined trait that you can implement to create a pass; the pass will be named after the type, and it will consist of a main loop that goes over each available MIR and applies run_pass.

Implementors

impl MirPass for AddCallGuards
[src]

Breaks outgoing critical edges for call terminators in the MIR.

Critical edges are edges that are neither the only edge leaving a block, nor the only edge entering one.

When you want something to happen "along" an edge, you can either do at the end of the predecessor block, or at the start of the successor block. Critical edges have to be broken in order to prevent "edge actions" from affecting other edges. We need this for calls that are codegened to LLVM invoke instructions, because invoke is a block terminator in LLVM so we can't insert any code to handle the call's result into the block that performs the call.

This function will break those edges by inserting new blocks along them.

NOTE: Simplify CFG will happily undo most of the work this pass does.
