Gabe Black 8a4af3668d ARM: Support forcing load/store multiple to use user registers. 2009-11-08 15:49:03 -08:00
Gabe Black bb903b6514 ARM: Simplify the load/store multiple generation code. 
Specifically, get rid of the big switch statement so more cases can be
handled. Enumerating all the possible settings doesn't scale well. Also do
some minor style clean up.
 2009-11-08 15:16:59 -08:00
Gabe Black 48525f581c ARM: Split the condition codes out of the CPSR. 
This allows those bits to be renamed while allowing the other fields to
control the behavior of the processor.

Gabe Black 78bd8fe44f ARM: Add back in spots for Rhi and Rlo, and use a named constant for LR. 2009-11-08 01:59:20 -08:00
Gabe Black f63c260d89 ARM: Get rid of the Raddr operand. 2009-11-08 01:57:34 -08:00
Gabe Black 4a454c4f47 ARM: Set up an intregs.hh for ARM. 
Add constants for all the modes and registers, maps for aliasing, functions
that use the maps and range check, and use a named constant instead of a magic
number for the microcode register.
