Logically ORs the upper 16 bits of the contents of a general-purpose register with a 16-bit unsigned integer and stores the result in another general-purpose register.

The oris and oriu instructions logically OR the contents of general-purpose register (GPR) RS with the concatenation of a 16-bit unsigned integer, UI, and x'0000' and store the result in GPR RA.
The oris and oriu instructions have one syntax form and do not affect Condition Register Field 0 or the Fixed-Point Exception Register.
| RA | Specifies target general-purpose register where result of operation is stored. |
| RS | Specifies source general-purpose register for operation. |
| UI | Specifies a16-bit unsigned integer for operation. |
The following code ORs the upper 16 bits of the contents of GPR 4 with 0x0079 and stores the result in GPR 6:
# Assume GPR 4 contains 0x9000 3000. oris 6,4,0x0079 # GPR 6 now contains 0x9079 3000.
