Assembler in Ruby

Supporting arm, but aimed quite specifically at raspberry pi, arm v7, floating point included

Outputs Elf object files, with relocation support.

Constant table support exists but isn't very good. Some addressing modes are not supported or only partially supported.

Supported (pseudo)instructions:

adc, add, and, bic, eor, orr, rsb, rsc, sbc, sub, cmn, cmp, teq, tst, mov, mvn, strb, str, ldrb, ldr, push, pop, b, bl, bx, swi
Conditional versions of above
