* commit '12004a9a7f20e44f4da2ee6c372d5e1794c8d6c5': audiodsp/x86: yasmify vector_clipf_sse audiodsp: reorder arguments for vector_clipf Merged the version from Libav after a discussion with James Almer on IRC: 19:22 <ubitux> jamrial: opinion on 12004a9a7f20e44f4da2ee6c372d5e1794c8d6c5? 19:23 <ubitux> it was apparently yasmified differently 19:23 <ubitux> (it depends on the previous commit arg shuffle) 19:24 <ubitux> i don't see the magic movsxdifnidn in your port btw 19:24 <ubitux> it's a port from 1d36defe94c7d7ebf995d4dbb4f878d06272f9c6 19:25 <jamrial> seems better thanks to said arg shuffle 19:25 <jamrial> the loop is the same, but init is simpler 19:25 <jamrial> probably worth merging 19:25 <ubitux> OK 19:25 <ubitux> thanks 19:26 <jamrial> curious they didn't make len ptrdiff_t after the previous bunch of commits, heh 19:26 <ubitux> yeah indeed Both commits are merged at the same time to prevent a conflict with our existing yasmified ff_vector_clipf_sse.
