Min Kyu Jeong 5d5bf8cbc7 ARM: Fix IT state not updating when an instruction memory instruction faults. 2010-06-02 12:58:18 -05:00
Gabe Black 85ba2a3243 ARM: Decode the neon instruction space. 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.
 2010-06-02 12:58:18 -05:00
Gabe Black 22f15ab94e ARM: Combine some redundant cases in one of the data decode functions. 2010-06-02 12:58:18 -05:00
Gabe Black b6c2548a27 ARM: Get rid of the binary dumping function in utility.hh. 2010-06-02 12:58:17 -05:00
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.
