public MachineReflection()

Method Detail

countParameters

public static int countParameters(RVMMethod method)

Determine number/type of registers and parameters required to call specified method. Unlike the PowerPC code we count all the parameters, not just the ones that spill. This allow us to make enough space on the stack following the calling convention.

packageParameters

public static void packageParameters(RVMMethod method,
                                     Object thisArg,
                                     Object[] otherArgs,
                                     WordArray GPRs,
                                     double[] FPRs,
                                     byte[] FPRmeta,
                                     WordArray Parameters)

Collect parameters into arrays of registers/spills, as required to call specified method.
