Vince Weaver 8f6744c19c X86: add ULL to 1's being shifted in 64-bit values 
Some of the micro-ops weren't casting 1 to ULL before shifting,
which can cause problems.  On the perl makerand input this
caused some values to be negative that shouldn't have been.

The casts are done as ULL(1) instead of 1ULL to match others
in the m5 code base.

Gabe Black 4779020e13 ARM: Fix the integer register indexes. 
The PC indexes in the various register sets was defined in the section for
unaliased registers which was throwing off the indexing. This moves those
where they belong. Also, to make detecting accesses to the PC easier and
because it's in the same place in all modes, the intRegForceUser function
now passes it through as index 15.

Vince Weaver 53e27c0277 X86: Fix bugs in movd implementation. 
Unfortunately my implementation of the movd instruction had two bugs.

In one case, when moving a 32-bit value into an xmm register, the
lower half of the xmm register was not zero extended.

The other case is that xmm was used instead of xmmlm as the source
for a register move.  My test case didn't notice this at first
as it moved xmm0 to eax, which both have the same register
number.
 2009-11-10 11:29:30 -05:00
Vince Weaver e81cc233a6 X86: Remove double-cast in Cvtf2i micro-op 
This double cast led to rounding errors which caused
some benchmarks to get the wrong values, most notably lucas
which failed spectacularly due to CVTTSD2SI returning an
off-by-one value.  equake was also broken.

Vince Weaver 7da221ca82 syscall: missing initializer in getcwd call 
This one case was missed during the update to stack-based arguments.

Gabe Black bb903b6514 ARM: Simplify the load/store multiple generation code. 
Specifically, get rid of the big switch statement so more cases can be

Nathan Binkert 708faa7677 compile: wrap 64bit numbers with ULL() so 32bit compiles work

Gabe Black 48525f581c ARM: Split the condition codes out of the CPSR.

Gabe Black 4a454c4f47 ARM: Set up an intregs.hh for ARM. 
Add constants for all the modes and registers, maps for aliasing, functions
that use the maps and range check, and use a named constant instead of a magic
number for the microcode register.

Vince Weaver 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.
 2009-11-04 13:22:15 -05:00
Steve Reinhardt 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.

Vince Weaver 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.
 2009-11-04 00:47:12 -05:00
Vince Weaver 9b0a747dd4 X86: Hook up time syscall on X86 
This has been tested and verified that it works.
 2009-11-04 00:19:15 -05:00
Vince Weaver a12557439b X86: Add support for x86 psrldq and pslldq instructions 
These are complicated instructions and the micro-code might be suboptimal.

This has been tested with some small sample programs (attached)

The psrldq instruction is needed by various spec2k programs.
 2009-10-30 12:49:37 -04:00
Vince Weaver 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.
 2009-10-30 15:52:33 -04:00
Vince Weaver 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.
 2009-10-30 14:19:06 -04:00
Vince Weaver 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.
 2009-10-30 12:51:13 -04:00
Vince Weaver 9ad3acab5e SysCalls: Implement truncate64 system call 
This uses the new stack-based argument infrastructure.

Tested on x86 and x86_64.
 2009-10-30 12:31:55 -04:00
Gabe Black d6ff7929b3 Syscalls: Fix a warning turned error about an unused variable in m5.fast. 2009-10-31 13:20:22 -07:00
Gabe Black 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.

Nathan Binkert 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.

Vince Weaver 14691148cd Implement X86 sse2 movdqu and movdqa instructions 
The movdqa instruction should enforce 16-byte alignment.
This implementation does not do that.

These instructions are needed for most of x86_64 spec2k to run.

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.

Timothy M. Jones 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.

Vince Weaver 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.

This is currently how alpha handles this syscall.

This is needed for the gcc spec2k benchmarks to run.

Vince Weaver 30a185dcd0 Hook up the munmap() syscall for 32-bit x86. 
This is straightforward, as munmapFunc() doesn't do anything.
I've tested it with code running munmap() just in case.

This prevents redundant prefetches from being issued, solving the

in cache_impl.hh that several people have run into.
Eliminates "prefetch_cache_check_push" flag, neither setting of
which really solved the problem.
