public static class Spec.DetailExtra
extends Spec.Detail

Extension of Spec.Detail that requests an extra temporary register for the use of the action clause. For example, if multiplying two 32-bit registers generates a 64-bit result on the target architecture, you might need to request an extra Temp to have a place to put the high word of the result (before you throw it away). The DetailExtra element contains a list of identifiers naming the working temps that you are requesting.

syntax: %extra { ID-LIST }
