Hi Andrew,

Please find two patches, one is fixing the dmac issue with non odd-even register pairs (test added). The second patch tries to improve the size figures by managing the long immediate field.

Thanks,
Claudiu

  [ARC] Check for odd-even register when emitting double mac ops.
  [ARC] Avoid specific constants to end in limm field.
