including automatically fixing up addresses to deal with optionally executed Alpha gp update prolog. SConscript: Remove freebsd_events.cc and linux_events.cc. base/remote_gdb.cc: cpu/pc_event.cc: kern/system_events.cc: kern/system_events.hh: PCEvents now schedule themselves in constructor. cpu/pc_event.hh: PCEvents now schedule themselves in the constructor. Get rid of constructor versions that don't take an address and all the schedule() methods that are now unnecessary. kern/freebsd/freebsd_system.cc: kern/freebsd/freebsd_system.hh: Use new System methods to schedule function-based events. Move FreeBSD-specific function event classes into FreebsdSystem. kern/linux/linux_system.cc: kern/linux/linux_system.hh: Use new System methods to schedule function-based events. Move Linux-specific function event classes into LinuxSystem. kern/tru64/tru64_events.hh: PCEvents now schedule themselves in constructor. Add DebugPrintfrEvent to encapsulate raw setting as new type (to work better with new System function-event method.) kern/tru64/tru64_system.cc: Use new System methods to schedule function-based events. kern/tru64/tru64_system.hh: Add DebugPrintfrEvent to encapsulate raw setting as new type (to work better with new System function-event method.) sim/system.cc: sim/system.hh: Add functions to set up function-based events, including automatically fixing up addresses to deal with optionally executed Alpha gp update prolog. --HG-- extra : convert_revision : c2cf09144297b6602afe755a34a0a2227023783f
