Description

Interface Summary

BackendDerivation	BackendDerivation provides, in addition to the type and derivation information provided by Analysis.Maps.Derivation, a means to identify (polymorphically typed) callee-save registers.
BackendDerivation.Register

Class Summary

CHFinalMap	CHFinalMap is a slightly smarter FinalMap that, given a ClassHierarchy for context, aggressively makes methods final if the ClassHierarchy doesn't contain a reachable method which overrides it.
ClassDepthMap	A ClassDepthMap reports the nesting depth of a given class, with java.lang.Object given nesting depth 0.
DefaultClassDepthMap	A DefaultClassDepthMap computes class depth simply and efficiently.
DefaultFinalMap	DefaultFinalMap is a stupid implementation of FinalMap that just looks for the final access modifier.
DefaultInlineMap	A DefaultInlineMap returns the conservate answer that we can't inline anything.
DefaultNameMap	DefaultNameMap implements a JNI-compliant method name mangling, and class and field name mangling "in the spirit of" the JNI.
FieldMap	A FieldMap assigns an ordering to a set of fields.
FinalMap	A FinalMap determines whether a class or method is final.
InlineMap	An InlineMap maps an HField to a boolean value indicated whether the HField can be inlined.
MethodMap	A MethodMap assigns an ordering to the methods in a class.
NameMap	NameMap gives a translation from methods, classes, and fields to unique string labels legal in assembly code.
