bb903b6514 ARM: Simplify the load/store multiple generation code.
Specifically, get rid of the big switch statement so more cases can be
handled. Enumerating all the possible settings doesn't scale well. Also do
some minor style clean up.

5cf2e7ccf0 X86: Fix problem with movhps instruction
This problem is like the one fixed with movhpd a few weeks ago.
A +8 displacement is used to access memory when there should
be none.

This fix is needed for the perlbmk spec2k benchmark to run.

9098010e3f slicc: tweak file enumeration for scons
Right now .cc and .hh files are handled separately, but then
they're just munged together at the end by scons, so it
doesn't buy us anything.  Might as well munge from the start
since we'll eventually be adding generated Python files
to the list too.

a1042db290 X86: Enable x86_64 vsyscall support
64-bit vsyscall is different than 32-bit.
There are only two syscalls, time and gettimeofday.
On a real system, there is complicated code that implements these
without entering the kernel.  That would be complicated to implement in m5.
Instead we just place code that calls the regular syscalls (this is how
tools such as valgrind handle this case).

This is needed for the perlbmk spec2k benchmark.

a12557439b X86: Add support for x86 psrldq and pslldq instructions

5873ec2238 X86: Implement movd_Vo_Edp on X86
This patch implements the movd_Vo_Edp series of instructions.

It addresses various concerns by Gabe Black about which file the
instruction belonged in, as well as supporting REX prefixed
instructions properly.

This instruction is needed for some of the spec2k benchmarks, most
notably bzip2.

b2067840a6 X86: Implement the X86 sse2 haddpd instruction
This patch implements the haddpd instruction.

It fixes the problem in the previous version (pointed out by Gabe Black)
where an incorrect result would happen if you issue the instruction
with the same argument twice, i.e. "haddpd %xmm0,%xmm0"

This instruction is used by many spec2k benchmarks.

cf269025f9 X86: Hookup truncate/ftruncate syscalls on X86
This patch hooks up the truncate, ftruncate, truncate64 and ftruncate64
system calls on 32-bit and 64-bit X86.

These have been tested on both architectures.

ftruncate/ftruncate64 is needed for the f90 spec2k benchmarks.

3f722b991f Syscalls: Make system calls access arguments like a stack, not an array.
When accessing arguments for a syscall, the position of an argument depends on
the policies of the ISA, how much space preceding arguments took up, and the
"alignment" of the index for this particular argument into the number of
possible storate locations. This change adjusts getSyscallArg to take its
index parameter by reference instead of value and to adjust it to point to the
possible location of the next argument on the stack, basically just after the
current one. This way, the rules for the new argument can be applied locally
without knowing about other arguments since those have already been taken into
account implicitly.

All system calls have also been changed to reflect the new interface. In a
number of cases this made the implementation clearer since it encourages
arguments to be collected in one place in order and then used as necessary
later, as opposed to scattering them throughout the function or using them in
place in long expressions. It also discourages using getSyscallArg over and
over to retrieve the same value when a temporary would do the job.

25d9328689 license: Fix license on network model code
This mostly was a matter of changing the license owner to Princeton
which is as it should have been.  The code was originally licensed
under the GPL but was relicensed as BSD by Li-Shiuan Peh on July 27,
2009.  This relicensing was in an explicit e-mail to Nathan Binkert,
Brad Beckmann, Mark Hill, David Wood, and Steve Reinhardt.

The st_size entry was in the wrong place
 (see linux-2.6.29/arch/x86/include/asm/stat.h )

Also, the packed attribute is needed when compiling on a
64-bit machine, otherwise gcc adds extra padding that
break the layout of the structure.

03da1e53c2 syscall: Zero out memory that already exists during the brk system call.
Glibc often assumes that memory it receives from the kernel after a brk
system call will contain only zeros. This is important during a calloc,
because it won't clear the new memory itself. In the simulator, if the
new page exists, it will be cleared using this patch, to mimic the kernel's
functionality.

56154cff5e Enable getuid and getgid related syscalls on X86_SE
I've tested these on x86 and they work as expected.

In theory for 32-bit x86 we should have some sort of special
handling for the legacy 16-bit uid/gid syscalls, but in practice
modern toolchains don't use the 16-bit versions, and m5 sets the uid
and gid values to be less than 16-bits anyway.

This fix is needed for the perl spec2k benchmarks to run.
