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. This way we can wrap all of the functions inside the object, and not worry about namespace conflicts because no one outside this file will ever see it. base/loader/aout_object.cc: base/loader/aout_object.hh: base/loader/ecoff_object.cc: base/loader/ecoff_object.hh: base/loader/elf_object.cc: base/loader/elf_object.hh: base/loader/object_file.cc: base/loader/object_file.hh: Add enums to ObjectFile to indicate the object's architecture and operating system. cpu/exec_context.cc: prog.hh is now process.hh cpu/exec_context.hh: prog.hh is now process.hh move architecture-specific syscall arg accessors into ExecContext cpu/simple_cpu/simple_cpu.cc: No need to include prog.hh (which has been renamed) sim/process.cc: sim/process.hh: LiveProcess is now effectively an abstract base class. New LiveProcess::create() function takes an object file and dynamically picks the appropriate subclass of LiveProcess to handle the syscall interface that file expects (currently Tru64 or Linux). --HG-- rename : arch/alpha/fake_syscall.cc => arch/alpha/alpha_tru64_process.cc rename : sim/prog.cc => sim/process.cc rename : sim/prog.hh => sim/process.hh extra : convert_revision : 4a03ca7d94a34177cb672931f8aae83a6bad179a
