Ali Saidi 5268067f14 ARM: Fix SPEC2000 benchmarks in SE mode. With this patch all 
Spec2k benchmarks seem to run with atomic or timing mode simple
CPUs. Fixed up some constants, handling of 64 bit arguments,
and marked a few more syscalls ignoreFunc.

Gabe Black 85ba2a3243 ARM: Decode the neon instruction space. 2010-06-02 12:58:18 -05:00
Gabe Black e50e6a260f ARM: Add a comment to vfp.cc that explains the asm statements. 2010-06-02 12:58:18 -05:00
Gabe Black 10031a0327 ARM: Move some case values out of ##included files. 
This will help keep the high level decode together and not have it spread into
the subordinate decode stuff. The ##include lines still need to be on a line
by themselves, though.

Gabe Black 358fdc2a40 ARM: Decode to specialized conditional/unconditional versions of instructions. 
This is to avoid condition code based dependences from effectively serializing
instructions when the instruction doesn't actually use them.
