Add reference page for newyork IR

[elle-j]

Adds a per-operation reference for the newyork IR to the compiler book for easily being able to view printed syntax, operand and result types, examples, etc. for any operation. Using easily readable syntax notation. The new page is partly inspired by MLIR's docs.

Example entry

and

(Expression::Binary with BinaryOperation::And)

Description

Bitwise AND. The common idiom for type narrowing: a constant mask on the right lets forward analysis pick up a tight result width.

Syntax

and($lhs[: <type>], $rhs[: <type>])

Example

let v2 := and(v0, v1)
let v3 := and(v0, 0xff)     // type inference narrows result to i8

Operands

Name	Type	Notes
lhs	i256	—
rhs	i256	—

Result and purity

Result	Purity
min(width(lhs), width(rhs)) — AND can only clear bits, so the result fits in the narrower operand	Pure

Annotations

None.
