Timothy M. Jones 835a55e7f3 POWER: Add support for the Power ISA 
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.

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.

Vince Weaver 22dc2b5595 Ignore rt_sigaction() syscalls on x86 and x86_64 
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.

Nathan Binkert 160bcf4442 python: Fix m5.defines so grabbing flags works correctly 2009-09-26 12:51:37 -07:00
Steve Reinhardt 4bec4702e9 O3: Add flag to control whether faulting instructions are traced. 
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.

Steve Reinhardt f679630788 Minor cleanup: Use the blockAlign() method where it applies in the cache. 2009-09-26 10:50:50 -07:00
Steve Reinhardt 72cfed4164 Force prefetches to check cache and MSHRs immediately prior to issue. 
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.

Steve Reinhardt f28ea7a6c9 O3: Mark fetch stage as active if it faults. 
Otherwise if the rest of the pipeline is idle then
fault will never propagate to commit to be handled,
causing CPU to deadlock.

Nathan Binkert 2278363015 slicc: Pure python implementation of slicc. 
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
