Struct regalloc2::SpillSlot

source · [−]

pub struct SpillSlot { /* private fields */ }

Expand description

A spillslot is a space in the stackframe used by the allocator to temporarily store a value.

The allocator is responsible for allocating indices in this space, and will specify how many spillslots have been used when the allocation is completed.

Implementations

source

impl SpillSlot
