2006-03-07Corrected a mispelling of "unimplemented".Gabe Black
arch/sparc/stacktrace.hh: - Change the StackTrace code so that the class can more easily be cleaned out and reused to avoid extra allocations. - Allow trace() to accept a static instruction pointer so it can determine if the instruction is worth tracing.

The actual function still resides in the execution context. arch/sparc/faults.cc: AlphaFault is now an abstract class. arch/sparc/faults.hh: AlphaFault is now an abstract class.

2006-03-03Changes to support automatic renaming of the shadow registers at decode ↵Kevin Lim
time. This requires using an ExtMachInst (uint64_t) instead of the normal MachInst; the ExtMachInst is packed with extra decode context information. In the case of Alpha, the PAL mode is included. The shadow registers are folded into the normal integer registers to ease renaming indexing. Include the removed Opcdec class of instructions for faulting when a pal mode only instruction is decoded in non-pal mode. arch/alpha/ev5.cc: Changes to automatically map the shadow registers if the instruction is in PAL mode. arch/alpha/isa/branch.isa: arch/alpha/isa/decoder.isa: arch/alpha/isa/fp.isa: arch/alpha/isa/int.isa: arch/alpha/isa/mem.isa: arch/alpha/isa/pal.isa: arch/alpha/isa/unimp.isa: Changes for automatically using the shadow registers. Now instructions must decode based on an ExtMachInst, which is a MachInst with any decode context information concatenated onto the higher order bits. arch/alpha/isa/main.isa: Changes for automatically using the shadow registers. Now instructions must decode based on an ExtMachInst, which is a MachInst with any decode context information concatenated onto the higher order bits. The decoder (for Alpha) uses the 32nd bit in order to determine if the machine is in PAL mode. If it is, then it refers to the reg_redir table to determine the true index of the register it is using. Also include the opcdec instruction definition. arch/alpha/isa_traits.hh: Define ExtMachInst type that is used by the static inst in order to decode the instruction, given the context of being in pal mode or not. Redefine the number of Int registers, splitting it into NumIntArchRegs (32) and NumIntRegs (32 + 8 shadow registers). Change the dependence tags to reflect the integer registers include the 8 shadow registers. Define function to make an ExtMachInst. Currently it is somewhat specific to Alpha; in the future it must be decided to make this more generic and possibly slower, or leave it specific to each architecture and ifdef it within the CPU. arch/isa_parser.py: Have static insts decode on the ExtMachInst. base/remote_gdb.cc: Support the automatic remapping of shadow registers. Remote GDB must now look at the PC being read in order to tell if it should use the normal register indices or the shadow register indices. cpu/o3/regfile.hh: Comment out the pal registers; they are now a part of the integer registers. cpu/simple/cpu.cc: Create an ExtMachInst to decode on, based on the normal MachInst and the PC of the instructoin. cpu/static_inst.hh: Change from MachInst to ExtMachInst to support shadow register renaming. --HG-- extra : convert_revision : 1d23eabf735e297068e1917445a6348e9f8c88d5

This changeset removes a check that prevents quiescing when an interrupt is pending. *** You should only call quiesce if that isn't a problem. *** arch/alpha/isa/decoder.isa: sim/pseudo_inst.cc: sim/pseudo_inst.hh: Add quiesceNs, quiesceCycles, quisceTime and m5panic pseudo ops. These quiesce for a number of ns, cycles, report how long we were quiesced for, and panic the simulator respectively. The latter is added to the panic() function in the console and linux kernel instead of executing an infinite loop until someone notices. cpu/exec_context.cc: cpu/exec_context.hh: Add a quiesce end event to the execution contexted which upon executing wakes up a CPU for quiesceCycles/quiesceNs. util/m5/Makefile: Make the makefile more reasonable util/m5/m5.c: update the m5op executable to use the files from the linux tree util/m5/m5op.S: update m5op.S from linux tree util/m5/m5op.h: update m5op.h from linux tree --HG-- rename : util/m5/m5op.s => util/m5/m5op.S extra : convert_revision : 3be18525e811405b112e33f24a8c4e772d15462d

2006-02-28Cleaned up and slightly reorganized the Fault class heirarchy.Gabe Black
arch/alpha/ev5.cc: Changed c style casts of Faults to dynamic_casts arch/alpha/faults.cc: AlphaFault is now an abstract class. arch/alpha/faults.hh: AlphaFault is now an abstract class. Also, AlphaMachineCheckFault and AlphaAlignmentFault multiply inherit from both AlphaFault and from MachineCheckFault and AlignmentFault respectively. These classes get their name from the generic classes. cpu/o3/alpha_cpu_impl.hh: Changed a c style cast to a dynamic_cast for a Fault sim/faults.hh: All generic Fault classes are now abstract. Also, MachineCheckFault and AlignmentFault inherit FaultBase as a virtual base class to help resolve ambiguities when they are multiply inherited in ISA specific classes. The override the isMachineCheckFault and isAlignmentFault functions appropriately, and provide a standard name for these faults. --HG-- extra : convert_revision : 2cb906708e3eaec4a12587484c09e50ed6ef88fc
