Fixes so m5 compiles on gcc 3.4, which has much stricter syntax. Most changes come from templated code, which is evaluated slightly differently than in previous versions of gcc. arch/alpha/alpha_linux_process.cc: Alphabetize includes. arch/alpha/vptr.hh: Change the constants that are being used for alpha pagebytes to come from the ISA. base/random.hh: cpu/static_inst.cc: sim/param.cc: Fix up template syntax. base/range.hh: Include iostream for << operator. base/res_list.hh: base/statistics.hh: cpu/simple_cpu/simple_cpu.hh: cpu/static_inst.hh: sim/eventq.hh: sim/param.hh: Fixup for templated code to resolve different scope lookup in gcc 3.4.

Fix up template syntax. sim/serialize.cc: Include errno.h. sim/startup.cc: Change startupq. queue was getting destructed before all things had called ~StartupCallback(), which lead to a segfault. This puts startupq in global space, and we allocate it ourselves.

Restructuring of LiveProcess etc. to support multiple emulated OS syscall interfaces, and specific support for Alpha Linux. Split syscall emulation functions into several groups, based on whether they depend on the specific OS and/or architecture (and all combinations of above), including the use of template functions to support syscalls with slightly different constants or interface structs. arch/alpha/alpha_tru64_process.cc: Incorporate full Tru64 object definition here, including structure and constant definitions.

Changes that get rid of the OSFlags and derive a new class of this format <architecture>-<OS>. This class is derived from the original <OS> class and is used to define information that is both architecure and OS specific (for example, the AlphaLinux class is derived from the Linux class and defined in arch/alpha/linux/linux.hh). SConscript: no need to compile linux.cc and tru64.cc now, since openFlagsTable has been moved arch/alpha/SConscript: compile linux.cc and tru64.cc within alpha arch. arch/alpha/linux/process.cc: template syscall functions on AlphaLinux instead of Linux ... AlphaLinux is derived off of Linux arch/alpha/tru64/process.cc: template syscall functions on AlphaTru64 instead of Linux ... AlphaTru64 is derived off of Linux moved tableFunc syscall function into this file arch/mips/SConscript: compile mips_linux.cc for openFlags table arch/mips/isa_traits.hh: remove constants from here arch/mips/linux_process.cc: template syscall functions on MipsLinux instead of Linux ... MipsLinux is derived off of Linux kern/linux/linux.hh: remove OSFlags kern/tru64/tru64.hh: remove OSFlags def., openFlagTable, and tableFunc ... sim/syscall_emul.hh: go back to using "OS" instead of "OSFlags" arch/alpha/linux/linux.cc: defines openFlagTable arch/alpha/linux/linux.hh: arch/alpha/tru64/tru64.hh: Alpha Linux constants placed here in class derived from Linux class arch/alpha/tru64/tru64.cc: defines openFlagTable for AlphaTru64 arch/mips/mips_linux.cc: MIPS Linux open flag table arch/mips/mips_linux.hh: Mips Linux constants placed here in class derived from Linux class --HG-- extra : convert_revision : e6c1c2c895429c28fd141732e223e897ab19315e

Fixes so m5 compiles on gcc 3.4, which has much stricter syntax. Most changes come from templated code, which is evaluated slightly differently than in previous versions of gcc. arch/alpha/alpha_linux_process.cc: Alphabetize includes. arch/alpha/vptr.hh: Change the constants that are being used for alpha pagebytes to come from the ISA. base/random.hh: cpu/static_inst.cc: sim/param.cc: Fix up template syntax. base/range.hh: Include iostream for << operator. base/res_list.hh: base/statistics.hh: cpu/simple_cpu/simple_cpu.hh: cpu/static_inst.hh: sim/eventq.hh: sim/param.hh: Fixup for templated code to resolve different scope lookup in gcc 3.4. This defers the lookup of the function/variable until actual instantiation time by making it dependent on the templated class/function. base/trace.cc: Fix call to new. base/trace.hh: Fix up #define to have full path. cpu/base_cpu.cc: Fix up call to new. dev/etherlink.hh: dev/ns_gige.hh: dev/sinic.hh: Fixup for friend class/function declaration. g++ 3.4 no longer allows typedefs to be declared as a friend class. dev/pcidev.hh: Fix up re-definition of access level to params. kern/linux/linux_syscalls.hh: kern/tru64/tru64_syscalls.hh: Fix up header. Fix up template syntax. sim/serialize.cc: Include errno.h. sim/startup.cc: Change startupq. queue was getting destructed before all things had called ~StartupCallback(), which lead to a segfault. This puts startupq in global space, and we allocate it ourselves. Other code may be similar to this and may need changing in the future. sim/syscall_emul.hh: Include cpu/exec_context.hh and sim/process.hh, as forward declarations are no longer sufficient. sim/universe.cc: Include errno.h --HG-- extra : convert_revision : e49d08ee89eb06a28351f02bafc028ca6652d5af
