Its in the Evergreen ISA docs (it might only be evergreen they managed this). ALU_WORD1_OP2 ALU_INST [17:7] enum(11) Instruction. The top three bits of this field must be zero. Gaps in opcode values are not marked in the list below. See Chapter 7 for descriptions of each instruction. Opcodes 0..95 can be used in either the Vector or Trans unit. Opcodes 128..159 are Trans only. Opcodes 160..255 are vector only.
