	MOVK $(0<<16), R10 will be reported as an error by the assembler.

Special Cases.

(1) umov is written as VMOV.

(2) br is renamed JMP, blr is renamed CALL.

(3) No need to add "W" suffix: LDARB, LDARH, LDAXRB, LDAXRH, LDTRH, LDXRB, LDXRH.

(4) In Go assembly syntax, NOP is a zero-width pseudo-instruction serves generic purpose, nothing
