arch/alpha/ev5.cc: Commented out the intr_post function since it's not used. If this really -is- needed, it should be moved into the fault class. arch/alpha/faults.cc: arch/alpha/faults.hh: Moved the fault invocation code into the fault class fully, and got rid of the need for isA. cpu/exec_context.cc: cpu/exec_context.hh: Removed the trap function from the ExecContext. The faults will execute normally in full system mode, but always panic in syscall emulation mode. cpu/ozone/cpu.hh: cpu/simple/cpu.hh: Changed the execution context executing a fault to a fault executing on the execution context. sim/faults.cc: If not in full system mode, trying to invoke a fault causes a panic. sim/faults.hh: Removed the isA function. --HG-- extra : convert_revision : 894dc8f0755c8efc4b7ef5a09fb2cf7373042395
