Description
Class Summary | |
---|---|
BasicGCInfo | BasicGCInfo selects as GC points all
call sites and backward branches. |
ClassFieldMap | A ClassFieldMap is a FieldMap for
non-static fields of a class. |
ClassMethodMap | A ClassMethodMap is a method map for virtual methods of
an object (not static, not private, not constructors). |
GCTraceStore | GCTraceStore traces stores for the purposes of garbage collection. |
InitializerOrdering | InitializerOrdering computes a topological sort of
the static initializer call graph designed to ensure that
classes are initialized in the correct order. |
InsertWriteBarrier | InsertWriteBarrier instruments any writes to pointer
locations with a store check. |
InterfaceMethodMap | InterfaceMethodMap provides a mapping from interface
methods to the offset that the method-pointers should have on the
object layout. |
JLSRuntimeInformation | JLSRuntimeInformation contains the basic runtime information
required by the
Java
Language Specification. |
MakeGCThreadSafe | MakeGCThreadSafe adds checks to see whether another thread
has caused a GC, and if so, halts the current thread by calling out to
the runtime. |
PackedClassFieldMap | PackedClassFieldMap is a FieldMap for
non-static fields of a class which attempts to maximally fill holes
in the data structure (even if this means commingling a subclass'
fields with those of its superclass) in order to minimize the
space required by objects. |
SortedClassFieldMap | A SortedClassFieldMap is an extension of
ClassFieldMap which sorts object fields to
minimize "holes" between fields. |
This package contains the various analyses needed for the backend. These are not generic optimizations; they are specific information directly needed by the back end. Examples would include class/interface numbering, code reordering for cache locality, certain escape analyses, etc.
All analyses that don't easily fit into a single class should have their own subpackage under harpoon.Backend.Analysis.
