Gabe Black beb759912b ARM: Move the modified_imm function from all ARM instructions to just data processing ones. 2010-06-02 12:58:02 -05:00

Gabe Black 93a3714816 ARM: Move the templates for predicated instructions into a separate file. 
This allows the templates to all be available at the same time before any of
the formats, etc. This breaks an artificial circular dependence.

Gabe Black 04300e33d4 ARM: Remove the special naming for the new memory instructions. 
These are the only memory instructions now.
 2010-06-02 12:58:01 -05:00
Gabe Black deb6e8f805 ARM: Eliminate the old memory formats which are no longer used. 2010-06-02 12:58:01 -05:00
Gabe Black 1905024766 ARM: Eliminate decoding for the very deprecated FPA instructions. 2010-06-02 12:58:01 -05:00
Gabe Black 55465844dc ARM: Make the addressing mode 3 loads/stores use the externally defined instructions. 2010-06-02 12:58:01 -05:00
Gabe Black 36b6ca2ce3 ARM: Pull double memory instructions out of the decoder. 2010-06-02 12:58:01 -05:00
Gabe Black 79b288f7b5 ARM: Force the condition code for 16 bit thumb instructions to be unconditional. 
Before, because 16 bit thumb instructions didn't set the upper 16 bits of the
ExtMachInst, that field would be interpretted as "equals".

Gabe Black a86491fbf2 ARM: Decode 16 bit thumb PC relative memory instructions. 2010-06-02 12:58:01 -05:00

Gabe Black 462cf6f49b ARM: Make single stores decode to the new external store instructions. 2010-06-02 12:58:01 -05:00
Gabe Black 3b0f3b1ee2 ARM: Add a .w to the disassembly of 32 bit thumb instructions. 
This isn't technically correct since the .w should only be added if there are
32 and 16 bit encodings, but always having it always is better than never
having it.
