Validation Rules

  • Operands and result types must match the instruction signature.
  • The instruction must appear in a valid structured control context.

Common Mistakes

  • Using the instruction with the wrong operand type.
  • Forgetting that WAT validation is stack-typed.
Example
(func $example
  ;; i64.ne example
)
