This patch moves VMLADDUHM to decodetree a creates a gvec implementation using mul_vec and add_vec. rept loop master patch 8 12500 0,01810500 0,00903100 (-50.1%) 25 4000 0,01739400 0,00747700 (-57.0%) 100 1000 0,01843600 0,00901400 (-51.1%) 500 200 0,02574600 0,01971000 (-23.4%) 2500 40 0,05921600 0,07121800 (+20.3%) 8000 12 0,15326700 0,21725200 (+41.7%) The significant difference in performance when REPT is low and LOOP is high I think is due to the fact that the new implementation has a higher translation time, as when using a helper only 5 TCGop are used but with the patch a total of 10 TCGop are needed (Power lacks a direct mul_vec equivalent so this instruction is implemented with the help of 5 others, vmuleu, vmulou, vmrgh, vmrgl and vpkum).
