From 7c4c623302dca7da95b1c95d4968f4ef76de391d Mon Sep 17 00:00:00 2001 From: Gabe Black Date: Sat, 4 Mar 2006 03:09:23 -0500 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. --HG-- extra : convert_revision : b4754e7ca8328672d07e1394c4d162e199606b53 --- arch/sparc/process.cc | 56 +++++++++++++++++++++++++++++++++++++++++++++++++++ arch/sparc/process.hh | 45 +++++++++++++++++++++++++++++++++++++++++ 2 files changed, 101 insertions(+) create mode 100644 arch/sparc/process.cc create mode 100644 arch/sparc/process.hh (limited to 'arch/sparc') diff --git a/arch/sparc/process.cc b/arch/sparc/process.cc new file mode 100644 index 000000000..53a215379 --- /dev/null +++ b/arch/sparc/process.cc @@ -0,0 +1,56 @@ +/* + * Copyright (c) 2003-2004 The Regents of The University of Michigan + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions are + * met: redistributions of source code must retain the above copyright + * notice, this list of conditions and the following disclaimer; + * redistributions in binary form must reproduce the above copyright + * notice, this list of conditions and the following disclaimer in the + * documentation and/or other materials provided with the distribution; + * neither the name of the copyright holders nor the names of its + * contributors may be used to endorse or promote products derived from + * this software without specific prior written permission. + * + * THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS + * "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT + * LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR + * A PARTICULAR PURPOSE ARE DISCLAIMED.
