dc86f3229c X86: Fix a comment and adjust the stack base address. 
The stack base on my development machine starts one page below where it needs to. I don't know why it does, but I've duplicated it in m5.

e996ff7497 X86: Fix up auxiliary vectors. 
The type constants should go into an architecture independent spot since they are universal to all Linux elf binaries. The right value for some of the vectors needs to be determined. Also, x86 does not store argc or argv_array_base in registers like some other architectures.

d1e533a1e2 X86: Fix argument register indexing. 
Code was assuming that all argument registers followed in order from ArgumentReg0. There is now an ArgumentReg array which is indexed to find the right index. There is a constant, NumArgumentRegs, which can be used to protect against using an invalid ArgumentReg.

57428b8b0b X86: Fix carry calculation for subtraction based microops. 
The carry flag should be calculated using the -complement- of the second operand, not it's negation. The carry in which is part of computing the 2's complement may induce a carry, but if you've already caused the carry before you get the carry computing logic involved, it will miss it.

abc76f20cb Major changes to how SimObjects are created and initialized. Almost all 
creation and initialization now happens in python.  Parameter objects
are generated and initialized by python.  The .ini file is now solely for
debugging purposes and is not used in construction of the objects in any
way.

This doesn't handle high byte register accesses. It also highlights the fact that address size isn't actually being calculated, and that the size a microop uses needs to be overridable from the microassembly.

They are used with string instructions, but they use variables IP, DTF, and SSTF which don't appear to be documented.

69d259b6ae gcc 4.1 claims that mem_data might be used uninitialized, 
though I don't believe that's true.  Placate it anyway.

cea5435760 Make the GSR into a renamed control register. It should be split into a renamed part and a control part for the different bitfields, but the renamed part is all that's actually used.

e8ace88e89 create base/fenv.c to standerdize fenv across platforms. It's a c file and not a cpp file because c99 
(which defines fenv) doesn't necessarily extend to c++ and it is a problem with solaris. If really
desired this could wrap the ieeefp interface found in bsd* as well, but I see no need at the moment.

src/arch/alpha/isa/fp.isa:
src/arch/sparc/isa/formats/basic.isa:
    use m5_fesetround()/m5_fegetround() istead of fenv interface directly
src/arch/sparc/isa/includes.isa:
    use base/fenv instead of fenv directly
src/base/SConscript:
    add fenv to sconscript
src/base/fenv.hh:
src/base/random.cc:
    m5 implementation to standerdize fenv across platforms.
