RA unaffected
Assembler Syntax:
MOVHI %rA,IMM5
Example:
Not preceded by PFX:
MOVHI %g3,23 ; upper 16 bits of %g3 get 23
Preceded by PFX:
PFX %hi(100)
MOVHI %g3,%lo(100) ; upper 16 bits of %g3 get 100
Description:
Not preceded by PFX:
Copy IMM5 to the most significant half-word (bits 31..16) of RA. The least
significant half-word (bits 15..0) is unaffected.

The immediate operand is extended from 5 to 16 bits by concatenating the
contents of the K-register (11 bits) with IMM5 (5 bits). The 16-bit immediate value
