Example 31 with Interruptible

use of org.vmmagic.pragma.Interruptible in project JikesRVM by JikesRVM.

the class Memory method getVMSpace.

/**
 * Return the space associated with/reserved for the VM.  In the
 * case of Jikes RVM this is the boot image space.<p>
 *
 * The boot image space must be mapped at the start of available
 * virtual memory, hence we use the constructor that requests the
 * lowest address in the address space.  The address space awarded
 * to this space depends on the order in which the request is made.
 * If this request is not the first request for virtual memory then
 * the Space allocator will die with an error stating that the
 * request could not be satisfied.  The remedy is to ensure it is
 * initialized first.
 *
 * @return The space managed by the virtual machine.  In this case,
 * the boot image space is returned.
