Subject: Filled out the object file loader so it can load object files for
several OSs and architectures.
SConscript:
Added ./libelf as an include search directory. There might be a better spot for this than where I put it.
arch/SConscript:
Combined the linux_process.h and tru64_process.h into process.h. This allows each ISA to support processes from arbitrary OSs.
arch/alpha/SConscript:
Added process.cc as a source file. It provides an implementation of createProcess, which takes an object_file object and creates the appropriate process object, or dies.
base/loader/elf_object.cc:
Actually extract the OS and architecture from the elf file, rather than always guessing Alpha and Linux.
base/loader/object_file.hh:
Added constants for SPARC, MIPS, and Solaris, and changed the include for the Addr type.
sim/process.cc:
Pushed creation of specific process objects into the ISA specific code.
