Per the "Godson-2E User Manual v0.6", the Loongson 2E processor
does not implement the MOVZ/MOVN instructions
However it's enhanced version, the STLS2F01 processor, does.
See STLS2F01 User Manual (rev 1), chapter 13.1 "The compliance
overview":
The STLS2F01 processor implements several special MIPS IV
instructions as the supplement to the MIPS III instructions.
These instructions include two MIPS IV instructions (i.e. MOVZ
and MOVNZ) ...
