d6ff7929b3 Syscalls: Fix a warning turned error about an unused variable in m5.fast. 2009-10-31 13:20:22 -07:00

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.

14691148cd Implement X86 sse2 movdqu and movdqa instructions

This implementation does not do that.

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

776f9405fa Fix stat64 structure on 32-bit X86_SE 
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.

Eliminates "prefetch_cache_check_push" flag, neither setting of
which really solved the problem.

6e97feb8a5 X86: Make not taken conditional moves leave the destination alone. Adjust CMOVcc. 
The manuals from both AMD and Intel say that when writing to a 32 bit
destination in 64 bit mode, the upper 32 bits of the register are filled with
zeros. They also both say that the CMOV instructions leave their destination
alone when their condition fails. Unfortunately, it seems that CMOV will zero
extend its destination register whether or not it was supposed to actually do
a move on both platforms. This seems to be the only case where this happens,
but it would be hard to say for sure.

3a55fc5cac X86: Implement shift right/left double microops. 
This is my best guess as far as what these should do. Other existing microops
use implicit registers, mul1s and mul1u for instance, so this should be ok.
The microop that loads the implicit DoubleBits register would fall into one
of the microop slots for moving to/from special registers.
