Examples with RVMMember org.jikesrvm.classloader.RVMMember used on opensource projects

Example 1 with RVMMember

use of org.jikesrvm.classloader.RVMMember in project JikesRVM by JikesRVM.

the class BootImageWriter method disableObjectAddressRemapper.

/**
 * Stop recording objects referenced by RVM classes during
 * loading/resolution/instantiation.
 */
private static void disableObjectAddressRemapper() {
    Magic.setObjectAddressRemapper(null);
    // Remove bootimage writer's remapper object that was present when JTOC
    // was populated with JDK objects. It's not part of the bootimage and we
    // don't want to see warning messages about it when the bootimage is
    // written.
    RVMMember remapper = Entrypoints.magicObjectRemapperField;
    Statics.setSlotContents(remapper.getOffset(), 0);
}

Example 2 with RVMMember

use of org.jikesrvm.classloader.RVMMember in project JikesRVM by JikesRVM.

the class EntrypointHelper method getMember.

/**
 * Get description of virtual machine component (field or method).
 * <p>
 * Note: This is method is intended for use only by VM classes that need
 * to address their own fields and methods in the runtime virtual machine
 * image.  It should not be used for general purpose class loading.
 * @param classDescriptor  class  descriptor - something like "Lorg/jikesrvm/RuntimeEntrypoints;"
 * @param memberName       member name       - something like "invokestatic"
 * @param memberDescriptor member descriptor - something like "()V"
 * @return corresponding RVMMember object
