Helpers for recognizing common Cranelift instruction patterns.

Implementations§

Source§

impl CraneliftInstPattern

Source

pub fn is_pure_arith(instr: &CraneliftInstr) -> bool

Return true if instr is a pure arithmetic (no side effects, no memory) instruction.

Source

pub fn is_terminator(instr: &CraneliftInstr) -> bool

Return true if instr is a terminator (ends a block).

Source

pub fn has_side_effects(instr: &CraneliftInstr) -> bool

Return true if instr has side effects (memory or control flow).

Source

pub fn iconst_value(instr: &CraneliftInstr) -> Option<i64>

Try to extract the constant value from an Iconst instruction.
