Summary: This patch remaps the assembly idiom 'move' to 'or' instead of 'daddu' or 'addu'. The use of addu/daddu instead of or as move was highlighted as a performance issue during the analysis of a recent 64bit design. Originally move was encoded as 'or' by binutils but was changed for the r10k cpu family due to their pipeline which had 2 arithmetic units and a single logical unit, and so could issue multiple (d)addu based moves at the same time but only 1 logical move. This patch preserves the disassembly behaviour so that disassembling a old style (d)addu move still appears as move, but assembling move always gives an or Patch by Simon Dardis.
