Interface Summary

Interface	Description
CodeCacheProvider	Access to code cache related details and requirements.
CodeUtil.RefMapFormatter
DataSection.DataBuilder
RegisterConfig	A register configuration binds roles and attributes to physical registers.

Class Summary

Class	Description
AbstractAddress	Abstract base class that represents a platform specific address.
Architecture	Represents a CPU architecture, including information such as its endianness, CPU registers, word width, etc.
BytecodeFrame	Represents the Java bytecode frame state(s) at a given position including locations where to find the local variables, operand stack values and locked objects of the bytecode frame(s).
BytecodePosition	Represents a code position, that is, a chain of inlined methods with bytecode locations, that is communicated from the compiler to the runtime system.
CalleeSaveLayout	The callee save area (CSA) is a contiguous space in a stack frame used to save (and restore) the values of the caller's registers.
CallingConvention	A calling convention describes the locations in which the arguments for a call are placed and the location in which the return value is placed if the call is not void.
CodeUtil	Miscellaneous collection of utility methods used by jdk.internal.jvmci.code and its clients.
CodeUtil.DefaultRefMapFormatter	Formats a location present in a register or frame reference map.
CodeUtil.DefaultRegFormatter	Formats a location in a register reference map.
CodeUtil.NumberedRefMapFormatter
CompilationResult	Represents the output from compiling a method, including the compiled machine code, associated data and references, relocation information, deoptimization information, etc.
CompilationResult.Call	Represents a call in the code.
CompilationResult.CodeAnnotation	Provides extra information about instructions or data at specific positions in CompilationResult.getTargetCode().
CompilationResult.CodeComment	A string comment about one or more instructions at a specific position in the code.
CompilationResult.ConstantReference
CompilationResult.DataPatch	Represents a code site that references some data.
CompilationResult.DataSectionReference
CompilationResult.ExceptionHandler	Represents exception handler information for a specific code position.
CompilationResult.Infopoint	Represents an infopoint with associated debug info.
CompilationResult.JumpTable	Describes a table of signed offsets embedded in the code.
CompilationResult.Mark	Represents a mark in the machine code that can be used by the runtime for its own purposes.
CompilationResult.Reference	Represents some external data that is referenced by the code.
CompilationResult.Site	Represents a code position with associated additional information.
DataSection
DataSection.Data
DebugInfo	Represents the debugging information for a particular point of execution.
InstalledCode	Represents a compiled instance of a method.
Location	Represents a location where a value can be stored.
MemoryBarriers	Constants and intrinsic definition for memory barriers.
ReferenceMap
Register	Represents a target machine register.
Register.RegisterCategory	A platform specific register type that describes which values can be stored in a register.
RegisterAttributes	A collection of register attributes.
RegisterSaveLayout	A map from registers to frame slots.
RegisterValue	Denotes a register that stores a value of a fixed kind.
StackLockValue	Represents lock information in the debug information.
StackSlot	Represents a compiler spill slot or an outgoing stack-based argument in a method's frame or an incoming stack-based argument in a method's caller's frame.
StackSlotValue	Common base class for real and virtual stack slots.
TargetDescription	Represents the target machine for a compiler, including the CPU architecture, the size of pointers and references, alignment of stacks, caches, etc.
UnsignedMath	Utilities for unsigned comparisons.
ValueUtil	Utility class for working with the Value class and its subclasses.
VirtualObject	An instance of this class represents an object whose allocation was removed by escape analysis.
VirtualStackSlot	VirtualStackSlots are stack slots that are not yet fixed to specific frame offset.

Enum Summary

Enum	Description
CallingConvention.Type	Constants denoting the type of a call for which a calling convention is requested.
InfopointReason	A reason for infopoint insertion.

Exception Summary

Exception	Description
BailoutException	Exception thrown when the compiler refuses to compile a method because of problems with the method.
InvalidInstalledCodeException	Exception thrown by the runtime in case an invalidated machine code is called.
SourceStackTrace	Class representing a exception with a stack trace of the currently processed position in the compiled Java program instead of the stack trace of the compiler.

Package jdk.internal.jvmci.code Description

Package that defines the interface between a Java application that wants to install code and the runtime. The runtime provides in implementation of the CodeCacheProvider interface. The method CodeCacheProvider.addMethod(jdk.internal.jvmci.meta.ResolvedJavaMethod, CompilationResult, jdk.internal.jvmci.meta.SpeculationLog, InstalledCode) can be used to install code for a given method.
