Logically ORs the contents of a general-purpose register with the complement of the contents of another general-purpose register and stores the result in a third general-purpose register.
The orc instruction logically ORs the contents of general-purpose register (GPR) RS with the complement of the contents of GPR RB and stores the result in GPR RA.
The orc instruction has two syntax forms. Each syntax form has a different effect on Condition Register Field 0.
|Syntax Form||Overflow Exception (OE)||Fixed-Point Exception Register||Record Bit (Rc)||Condition Register Field 0|
The two syntax forms of the orc instruction never affect the Fixed-Point Exception Register. If the syntax form sets the Record (Rc) bit to 1, the instruction affects the Less Than (LT) zero, Greater Than (GT) zero, Equal To (EQ) zero, and Summary Overflow (SO) bits in Condition Register Field 0.
|RA||Specifies target general-purpose register where result of operation is stored.|
|RS||Specifies source general-purpose register for operation.|
|RB||Specifies source general-purpose register for operation.|
