Hi Aurelien, I found that when qemu-system-mips64el executed 'movz' with -M mips, it would raise a reserved instruction exception. 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
