3ad03491ed Add Neg as a pseudo instruction, and fix RRX pseudo code expansion. 
Split some of the thumb code emission rules to make it easier to specify short-cut notations.

6fff181679 Add support for TBB/TBH instructions. 
Precisize rules for selection of thumb instructions.
Add short-cut notation support for most simple Thumb2 instructions ( add r1,#4 instead of add r1,r1,#4 ).

71cdedea82 Add missing NOP, and B instruction forms. 
Move ThumbFunc flag from section to symbol.
Make .w forms optional the other way around. If .w is explicitly put on an instruction the assembler should always chose a wide form.

cc418eef74 Added unified assembler syntax mode so it can be selected with $ASMMODE. 
Fixed bug in Mov instruction.
Added initial scanning of IT/LastInIT detection for proper instruction selection.
Disabled "wide" format flag detection again for now.

387824c1ee Added some APSR register bitmask definitions. 
Fixed a bunch of instruction encodings by comparing bulks of handwritten tests to binutils assembled versions.
Fixed emission of regsets of S and D registers above 15.
Fixed assembler reader for RRX shiftmode.
There can be a size postfix after a condition code in UAL assembler syntax. This has been added to the assembler reader.

d023c63ad0 Add a lot of instruction table entries and missing instructions for support of most ARM32 mode instructions from ARMv4 up ARMv7A. 
Add some VFP registers.
Rebuilt tables.
Added a lot of VFPv3 and Advanced SIMD(not supported yet) oppostfixes.
Implemented code in aasmcpu to generate binary code from the instructions. Only ARM32 supported so far.
