Enum rustc_mir::interpret::StackPopCleanup

pub enum StackPopCleanup {
    Goto {
        ret: Option<BasicBlock>,
        unwind: Option<BasicBlock>,
    },
    None {
        cleanup: bool,
    },
}

Variants

Goto

Jump to the next block in the caller, or cause UB if None (that's a function that may never return). Also store layout of return place so we can validate it at that layout. ret stores the block we jump to on a normal return, while unwind stores the block used for cleanup during unwinding.

Fields of Goto

ret: Option<BasicBlock>unwind: Option<BasicBlock>

None

Just do nothing: Used by Main and for the box_alloc hook in miri. cleanup says whether locals are deallocated. Static computation wants them leaked to intern what they need (and just throw away the entire ecx when it is done).

Fields of None

cleanup: bool
