2009-10-30SysCalls: Implement truncate64 system callVince Weaver
This uses the new stack-based argument infrastructure. Tested on x86 and x86_64.

2009-10-30Syscalls: Make system calls access arguments like a stack, not an array.Gabe Black
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.
2009-10-28license: Fix license on network model codeNathan Binkert
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.

2009-10-27X86: Replace "DISPLACEMENT" with disp in movhpd.Gabe Black
2009-10-27Fix problem with the x86 sse movhpd instruction.Vince Weaver
The movhpd instruction was writing to the wrong memory offset.
2009-10-21Implement X86 sse2 movdqu and movdqa instructionsVince Weaver
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.

2009-10-20hook up stat64 syscall on 32-bit X86_SEVince Weaver
2009-10-20Fix stat64 structure on 32-bit X86_SEVince Weaver
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.
2009-10-27test: Hello world test program for PowerTimothy M. Jones
includes reference outputs for the Hello World tests on simple-atomic and o3-timing.
2009-10-27POWER: Add support for the Power ISATimothy M. Jones
This adds support for the 32-bit, big endian Power ISA. This supports both integer and floating point instructions based on the Power ISA Book I v2.06.

2009-10-24syscall: Zero out memory that already exists during the brk system call.Timothy M. Jones
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.

2009-10-19Enable getuid and getgid related syscalls on X86_SEVince Weaver
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.
2009-10-16Ignore rt_sigaction() syscalls on x86 and x86_64Vince Weaver
This is currently how alpha handles this syscall. This is needed for the gcc spec2k benchmarks to run.

2009-10-10Hook up the munmap() syscall for 32-bit x86.Vince Weaver
This is straightforward, as munmapFunc() doesn't do anything. I've tested it with code running munmap() just in case.

2009-09-26rundiff: Don't flush stdout until after postcontext is printed.Steve Reinhardt
2009-09-26O3: Add flag to control whether faulting instructions are traced.Steve Reinhardt
When enabled, faulting instructions appear in the trace twice (once when they fault and again when they're re-executed). This flag is set by the Exec compound flag for backwards compatibility.
2009-09-26Minor cleanup: Use the blockAlign() method where it applies in the cache.Steve Reinhardt
2009-09-26Force prefetches to check cache and MSHRs immediately prior to issue.Steve Reinhardt
This prevents redundant prefetches from being issued, solving the occasional 'needsExclusive && !blk->isWritable()' assertion failure in cache_impl.hh that several people have run into. Eliminates "prefetch_cache_check_push" flag, neither setting of which really solved the problem.
2009-09-26O3: Mark fetch stage as active if it faults.Steve Reinhardt
Otherwise if the rest of the pipeline is idle then fault will never propagate to commit to be handled, causing CPU to deadlock.

2009-09-22slicc: Pure python implementation of slicc.Nathan Binkert
This is simply a translation of the C++ slicc into python with very minimal reorganization of the code. The output can be verified as nearly identical by doing a "diff -wBur". Slicc can easily be run manually by using util/slicc

Get rid of misc.py and just stick misc things in __init__.py Move utility functions out of SCons files and into m5.util Move utility type stuff from m5/__init__.py to m5/util/__init__.py Remove buildEnv from m5 and allow access only from m5.defines Rename AddToPath to addToPath while we're moving it to m5.util Rename read_command to readCommand while we're moving it Rename compare_versions to compareVersions while we're moving it. --HG-- rename : src/python/m5/convert.py => src/python/m5/util/convert.py rename : src/python/m5/smartdict.py => src/python/m5/util/smartdict.py
