b5f65c36c7 Corrected a mispelling of "unimplemented".
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.  This is moved from
    the CPU.
    - provide constants for special meaning PCs (user, console, unknown),
    instead of magic numbers
arch/sparc/stacktrace.hh:
    Added some typedefs for Addr and MachInst, and untemplatized StaticInstPtr
arch/sparc/stacktrace.hh:
    Made Addr a global type
arch/sparc/stacktrace.hh:
    bk cp ../alpha/stacktrace.hh stacktrace.hh

8106a80450 Pushed ev5.hh out of the non-alpha code.
arch/SConscript:
    ev5 should now be contained within alpha specific code.
arch/alpha/ev5.cc:
arch/alpha/isa_traits.hh:
    Added getInstAsid and getDataAsid functions. These should be removed when the SimpleScalar cpu model is removed.
arch/sparc/isa_traits.hh:
    Added getInstAsid and getDataAsid functions. These should be removed when the SimpleScalar cpu model is removed. Also made some small fixes.
cpu/o3/alpha_cpu.hh:
    Added typedefs which are required now that there isn't a using namespace EV5.
cpu/o3/alpha_cpu_impl.hh:
    Some small changes so that ev5.hh isn't needed directly.
cpu/o3/cpu.hh:
    Removed including ev5.hh, and pushed retrieving the Asid into the MiscRegFile.
cpu/o3/regfile.hh:
    Removed the include of ev5.hh, using namespace EV5, and the now redundant ipr array.

cd62fed1a7 The a.out and ecoff object file formats will only be supported on Alpha for now.
arch/SConscript:
    aout_machdep.h and ecoff_machdep.h are no longer bridging headers, since support of these formats is limitted to alpha.
base/loader/exec_aout.h:
    Include the alpha specific version of aout_machdep.h, since only the alpha version of aout will be supported for now.

    Include the alpha specific version of ecoff_machdep.h, since only the alpha version of ecoff will be supported for now.

b511128507 Some clean up work with faults.
arch/alpha/faults.cc:
    Renamed the _stat stat to a more descriptive _count, got rid of some old commented out code, and moved common fault handling code, ie recording that the fault happend and that it wasn't mispeculated, into the FaultBase class.
arch/alpha/faults.hh:
    Renamed the _stat stat to the more descriptive _count, and renamed the appropriate accessor functions.
kern/kernel_stats.cc:
kern/kernel_stats.hh:
    The fault statistics are now handled by the fault classes themselves.
sim/faults.cc:
    The default implementation of the "invoke" method now does what all faults should do first, ie record that the fault happened, and make sure the fault isn't being executed on a mispeculated execution path.
sim/faults.hh:
    There is now a default implementation of invoke, and the stat function is taken care of in the architecture specific fault classes.

e7825aab59 Changes to support automatic renaming of the shadow registers at decode 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.

2eff368dd0 Cleaned up some of the Fault system.
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.

arch/sparc/linux_process.cc:
arch/sparc/linux_process.hh:
    Formatting & doxygen.
arch/sparc/linux_process.cc:
    Added some more ioctl commands to ignore.
    Set unlink and rename to the new functions.
    Ignore setrlimit, times and rt_sigaction.
    Should eventually provide a function for times.
arch/sparc/linux_process.cc:
    Fixes for Linux emulation:
    - stat struct alignment
    - osf_{get,set}sysinfo return values
    - additional syscall numbers
    - initialize $r0 to 0

arch/sparc/linux_process.cc:
    Replaced the namespace declaration with including arch/alpha/isa_traits.hh
arch/sparc/linux_process.cc:
    fixup for bsd hosts. Some headers are included by default which means that
    more variables need TGT_ prefixes and there isn't a stat call (everything
    is a stat64 call) so we have to work around that a bit
