Description

Interface Summary

LocationFactory	The LocationFactory interface provides a means for the runtime system to get access to some global storage for its use.
LocationFactory.Location	The Locations returned by the LocationFactory allocation function are opaque data structures that permit only the creation of an accessor fragment in Tree form.
RegFileInfo.CommonLoc	Common super class for StackOffsetLoc and MachineRegLoc.
RegFileInfo.MachineRegLoc	Represents Machine Register Temps.
RegFileInfo.StackOffsetLoc	Represents Stack Offset Temps.
RegFileInfo.TempLocator	Defines function from (Temp x DefPoint) -> Set of CommonLoc.
Runtime.ObjectBuilder.ArrayInfo	Information needed to build an array object.
Runtime.ObjectBuilder.Info	General information about a built object's type and what label to use to refer to it.
Runtime.ObjectBuilder.ObjectInfo	Information needed to build a non-array object.

Class Summary

Code	Generic.Code is an abstract superclass of codeviews which use Instrs.
CodeGen	Generic.CodeGen is a general class for specific Backends to extend.
Frame	A Frame encapsulates the machine-dependent information needed for compilation.
GCInfo	A GCInfo object collects data needed for garbage collection and makes necessary annotations to the instruction stream.
GCInfo.DLoc	Derivation information stored as CommonLocs.
GCInfo.GCPoint	A GCPoint contains information about all the live objects that the garbage collector needs to add to the root set at a particular GC point.
GCInfo.WrappedMachineRegLoc	WrappedMachineRegLoc is a wrapper object for MachineRegLocs that implement special equals and hashCode methods.
GCInfo.WrappedStackOffsetLoc	WrappedStackOffsetLoc is a wrapper object for StackOffsetLocs that implement special equals and hashCode methods.
InstrBuilder	InstrBuilder defines an interface that general program transformations can call to generate needed assembly code blocks for arbitrary target architectures.
MaxMunchCG	MaxMunchCG is a MaximalMunchCGG specific extension of CodeGen.
RegFileInfo	RegFileInfo defines an interface that general program analyses can call to find out architecture specific information about the target machine's register file.
RegUseDefer	RegUseDefer performs a Temp -> Register mapping on Backend Codes.
Runtime	A Generic.Runtime provides runtime-specific information to the backend.
Runtime.ObjectBuilder	The ObjectBuilder constructs data tables in the IR.Tree form to represent static objects which may be needed by the runtime---primarily string constant objects.
Runtime.TreeBuilder	The TreeBuilder constructs bits of code in the IR.Tree form to handle various runtime-dependent tasks---primarily method and field access.
RuntimeInformation	RuntimeInformation is an abstract encapsulation of analysis information about native methods as executed by a particular runtime system.
TempBuilder	TempBuilder defines an interface that general program transformations can call to generate data structures to represent Temps.

Exception Summary

RegFileInfo.SpillException

SpillException tells a register allocator which Temps are appropriate for spilling in order to allocate space for another Temp.

Package harpoon.Backend.Generic Description

Abstract superclasses for machine- or runtime-dependent classes.

• The Generic.Frame class here ties together most of the other machine-specific information; it is a mix-in class.
• Generic.RuntimeInformation is used outside of the backend by general-purpose analysis routines in order to "see inside" native methods.
