Author: Vadim Girlin <vadimgir...@gmail.com> Date: Sun Aug 11 02:52:34 2013 +0400 r600g/sb: use MULADD workaround on R7xx for MULADD_IEEE Looks like the same issue that was seen with MULADD in trans slot on R7xx also affects MULADD_IEEE (maybe all OP3 instructions and MULADD is just a most frequently used?). So the workaround is to not allow affected instructions to be placed into the trans slot.
