51 -These 8xx t-slot only ops are implemented in all vector slots.
52 MUL_LIT, FLT_TO_UINT, INT_TO_FLT, UINT_TO_FLT
53 These 8xx t-slot only opcodes become vector ops, with all four
54 slots expecting the arguments on sources a and b. Result is
55 broadcast to all channels.
56 MULLO_INT, MULHI_INT, MULLO_UINT, MULHI_UINT, MUL_64
57 These 8xx t-slot only opcodes become vector ops in the z, y, and
58 x slots.

63 The w slot may have an independent co-issued operation, or if the
64 result is required to be in the w slot, the opcode above may be
65 issued in the w slot as well.
