64fe7af51a SPARC: Set up a lookup table for integer register flattening. 
Using a look up table changed the run time of the SPARC_FS solaris boot
regression from:

real    14m45.951s
user    13m57.528s
sys     0m3.452s

to:

real    12m19.777s
user    12m2.685s

b398b8ff1b Registers: Add a registers.hh file as an ISA switched header. 
This file is for register indices, Num* constants, and register types.
copyRegs and copyMiscRegs were moved to utility.hh and utility.cc.

dc35d2f125 scons: re-work the *Source functions to take more information. 
Start by turning all of the *Source functions into classes
so we can do more calculations and more easily collect the data we need.
Add parameters to the new classes for indicating what sorts of flags the
objects should be compiled with so we can allow certain files to be compiled
without Werror for example.

b0e9654f86 Commit m5threads package. 
This patch adds limited multithreading support in syscall-emulation
mode, by using the clone system call.  The clone system call works
for Alpha, SPARC and x86, and multithreaded applications run
correctly in Alpha and SPARC.

8882dc1283 Get rid of the Unallocated thread context state. 
Basically merge it in with Halted.
Also had to get rid of a few other functions that
called ThreadContext::deallocate(), including:
 - InOrderCPU's setThreadRescheduleCondition.
 - ThreadContext::exit().  This function was there to avoid terminating
   simulation when one thread out of a multi-thread workload exits, but we
   need to find a better (non-cpu-centric) way.

f1430941cf This brings M5 closer to modernity - the kernel being advertised is newer so it won't die on binaries compiled with newer glibc's, and enables use of TLS-toolchain built binaries for ALPHA_SE by putting auxiliary vectors on the stack. There are some comments in the code to help. Finally, stats changes for ALPHA are from slight perturbations to the initial stack frame, all minimal diffs. 2008-12-05 12:09:29 -05:00

e2c7618e50 This patch pulls out the auxiliary vector struct from individual ISA 
LiveProcesses to the base LiveProcess definition so anyone can use them.

4514f565e3 syscalls: fix latent brk/obreak bug. 
Bogus calls to ChunkGenerator with negative size were triggering
a new assertion that was added there.
Also did a little renaming and cleanup in the process.

4e02e7c217 python: Fix the reference counting for python events placed on the eventq. 
We need to add a reference when an object is put on the C++ queue, and remove
a reference when the object is removed from the queue.  This was not happening
before and caused a memory problem.

07969dbbf1 Right now a single thread cpu 1 could get assigned context Id != 1, depending 
on the order in which it's registered with the system.  To make them match,
here is a little change.
