Hi Zhi-zhou Zhang, You are correct. This should not be a reserved instruction exception on MIPS64 (nor should MOVN).

The mips spec describes movz as below: Mnemonic Instructio Defined in MIPS ISA MOVZ Move Conditional on Zero MIPS32 I think ISA-64 should support MIPS32 instructions for compatible. am I right? -- Regards, Zhizhou Zhang
