Struct souper_ir::ast::BlockPc

pub struct BlockPc {
    pub block: BlockId,
    pub predecessor: u32,
    pub x: Operand,
    pub y: Operand,
}

A block path condition.

Expresses that x is equal to y on an incoming predecessor to block in the control-flow graph.

Fields

block: BlockId

The basic block in question.

predecessor: u32

The ith control-flow predecessor of block.

Zero-indexed: must be less than block's total number of predecessors.

x: Operand

Must be equal to y if control-flow entered block via predecessor.

y: Operand

Must be equal to x if control-flow entered block via predecessor.
