The class was crammed into syscall_emul.hh which has tons of forward
declarations and template definitions. To clean it up a bit, moved the
class into separate files and commented the class with doxygen style
comments. Also, provided some encapsulation by adding some accessors and
a mutator.
The syscallreturn.hh file was renamed syscall_return.hh to make it consistent
with other similarly named files in the src/sim directory.
The DPRINTF_SYSCALL macro was moved into its own header file with the
include the Base and Verbose flags as well.

rename : src/sim/syscallreturn.hh => src/sim/syscall_return.hh
this patch fixes issues with changeset 11593
use the host's pwrite() syscall for pwrite64Func(),
as opposed to pwrite64(), because pwrite64() does
not work well on all distros.
undo the enabling of fstatfs, as we will add this
in a separate pate.
The current ignoreWarnOnceFunc doesn't really work as expected,
since it will only generate one warning total, for whichever
"warn-once" syscall is invoked first. This patch fixes that
behavior by keeping a "warned" flag in the SyscallDesc object,
allowing suitably flagged syscalls to warn exactly once per
syscall.
The identifier SYS_getdents is not available on Mac OS X. Therefore, its use
results in compilation failure. It seems there is no straight forward way to
implement the system call getdents using readdir() or similar C functions.
Hence the commit 6709bbcf564d is being rolled back.
This patch fixes a few minor issues that caused link-time warnings
when using LTO, mainly for x86. The most important change is how the
syscall array is created. Previously gcc and clang would complain that
the declaration and definition types did not match. The organisation
is now changed to match how it is done for ARM, moving the code that
was previously in syscalls.cc into process.cc, and having a class
variable pointing to the static array.
With these changes, there are no longer any warnings using gcc 4.6.3
with LTO.
src/arch/x86/SConscript:
Add in process source files.
src/arch/x86/isa_traits.hh:
Replace magic constant numbers with the x86 register names.
src/arch/x86/miscregfile.cc:
Make clear the miscreg file succeed. There aren't any misc regs, so clearing them is very easy.
src/arch/x86/process.hh:
An X86 process class.
src/base/loader/elf_object.cc:
Add in code to recognize x86 as an architecture.
src/base/traceflags.py:
Add an x86 traceflag
src/sim/process.cc:
Add in code to create an x86 process.
src/arch/x86/intregs.hh:
A file which declares names for the integer register indices.
src/arch/x86/linux/linux.cc:
src/arch/x86/linux/linux.hh:
A very simple translation of SPARC's linux.cc and linux.hh. It's probably not correct for x86, but it might not be correct for SPARC either.
src/arch/x86/linux/process.cc:
src/arch/x86/linux/process.hh:
An x86 linux process. The syscall table is split out into it's own file.
src/arch/x86/linux/syscalls.cc:
The x86 Linux syscall table and the uname function.
src/arch/x86/process.cc:
The x86 process base class.
tests/test-progs/hello/bin/x86/linux/hello:
An x86 hello world test binary.
