STACK_POINTER

public static final RegisterConstants.GPR STACK_POINTER

Register current stack pointer. NB the frame pointer is maintained in the processor.

THREAD_REGISTER

public static final RegisterConstants.GPR THREAD_REGISTER

Register holding a reference to thread local information

JTOC_REGISTER

public static final RegisterConstants.GPR JTOC_REGISTER

Register holding the value of the JTOC, only necessary when we can't directly address the JTOC

ALL_GPRS

public static final RegisterConstants.GPR[] ALL_GPRS

All general purpose registers

NUM_GPRS

public static final byte NUM_GPRS

Number of general purpose registers

ALL_FPRS

public static final RegisterConstants.FloatingPointMachineRegister[] ALL_FPRS

All floating point purpose registers NB with SSE x87 registers must be explicitly managed

NUM_FPRS

public static final byte NUM_FPRS

Number of floating point registers

VOLATILE_GPRS

public static final RegisterConstants.GPR[] VOLATILE_GPRS

Volatile general purpose registers. NB: the order here is important. The opt-compiler allocates the volatile registers in the order they appear here.

NUM_VOLATILE_GPRS

public static final int NUM_VOLATILE_GPRS

VOLATILE_FPRS

public static final RegisterConstants.FloatingPointMachineRegister[] VOLATILE_FPRS

Volatile floating point registers within the RVM. TODO: this should include XMMs

NUM_VOLATILE_FPRS

public static final int NUM_VOLATILE_FPRS

Number of volatile FPRs

NONVOLATILE_GPRS

public static final RegisterConstants.GPR[] NONVOLATILE_GPRS

Non-volatile general purpose registers within the RVM. Note: the order here is very important. The opt-compiler allocates the nonvolatile registers in the reverse of order they appear here. R3 (EBX) must be last, because it is the only non-volatile that can be used in instructions that are using r8 and we must ensure that opt doesn't skip over another nonvol while looking for an r8 nonvol.

NUM_NONVOLATILE_GPRS

public static final int NUM_NONVOLATILE_GPRS

Number of non-volatile GPRs

NONVOLATILE_FPRS

public static final RegisterConstants.FloatingPointMachineRegister[] NONVOLATILE_FPRS

Non-volatile floating point registers within the RVM.

public static final int NUM_NONVOLATILE_FPRS

Number of non-volatile FPRs

PARAMETER_GPRS

public static final RegisterConstants.GPR[] PARAMETER_GPRS

General purpose registers to pass arguments within the RVM

NUM_PARAMETER_GPRS

public static final int NUM_PARAMETER_GPRS

Number of parameter GPRs

PARAMETER_FPRS

public static final RegisterConstants.FloatingPointMachineRegister[] PARAMETER_FPRS

Floating point registers to pass arguments within the RVM

NUM_PARAMETER_FPRS

public static final int NUM_PARAMETER_FPRS

Number of parameter FPRs

RETURN_GPRS

public static final RegisterConstants.GPR[] RETURN_GPRS

GPR registers used for returning values

NUM_RETURN_GPRS

public static final int NUM_RETURN_GPRS

Number of return GPRs

Native volatile FPRS

NATIVE_NONVOLATILE_FPRS

public static final RegisterConstants.FloatingPointMachineRegister[] NATIVE_NONVOLATILE_FPRS
