Expand description

The shape of one expression node. See ExpressionTy for the meaning of each variant; this is the same inventory with the children abstracted.

Variants§

SizedInt

An integer literal.

Fields

§value: u64

The value.

§size: Option<usize>

The width the literal was written with, if any.

Ident(Ident)

A named storage location.

Load(LoadNode<'a, E>)

*[space]:size ptr.

Range(RangeNode<E>)

value[start, size].

SubPieceMsb

src(count): drop count low bytes.

Fields

§src: E

The value truncated.

§count: usize

Bytes dropped.

SubPieceLsb

src:count: keep count low bytes.

Fields

§src: E

The value truncated.

§count: usize

Bytes kept.

FunctionCall

A built-in function.

Fields

§builtin: Builtin

Which one.

§args: E::Args

Its arguments.

PcodeOp

A define pcodeop call.

Fields

§id: PCodeOpId

The operation.

§args: E::Args

Its arguments.

Unop

A unary operator.

Fields

§op: UnaryOperator

The operator.

§e: E

Its operand.

Binop

A binary operator.

Fields

§op: BinaryOperator

The operator.

§lhs: E

Left operand.

§rhs: E

Right operand.

Internal(&'static str)

A node that has no place in a consumer-form AST: a macro call or a deferred call. The passes reject it with PcodeLowerError::InternalNode.
