Dead
⚙️ This is an internal compiler API. (rustc_private)

This crate is being loaded from the sysroot, a permanently unstable location for private compiler dependencies. It is not intended for general use. Prefer using a public version of this crate from crates.io via Cargo.toml.

This local is not currently alive, and cannot be used at all.

Uninitialized
⚙️ This is an internal compiler API. (rustc_private)

This crate is being loaded from the sysroot, a permanently unstable location for private compiler dependencies. It is not intended for general use. Prefer using a public version of this crate from crates.io via Cargo.toml.

This local is alive but not yet initialized. It can be written to but not read from or its address taken. Locals get initialized on first write because for unsized locals, we do not know their size before that.

Live(Operand<Tag>)

A normal, live local. Mostly for convenience, we re-use the Operand type here. This is an optimization over just always having a pointer here; we can thus avoid doing an allocation when the local just stores immediate values and never has its address taken.
