nxu8_disas

An nX-U8/100 disassembler written in C.

Changes made on top of frsr's code

• Fixed some instructions
• Adjusted instruction syntaxes based on personal preferences
  • Tabs are used for spacing instead of spaces
  • Immediates does not have # as prefixes
  • Dbitadr and Rn.bitoffset are rewritten as bit, [address] and bit, Rn
  • Indirect addressing modes have brackets now, for example: st r0, 0:[811Dh]
  • The colons in b/bl Dadr are removed, for example bl 03130h
  • lea Dadr has brackets now: lea [FFFCh]

Known bugs

• #imm7 does not show sign properly (add er0, F0h actually adds FFF0h(-10h) to ER0)
• extbw shows the register twice (extbw er0, er0)

Copying

Ask frsr, I didn't do anything :p
