Copies the contents of one floating-point register into another floating-point register.
The fmr instruction places the contents of floating-point register (FPR) FRB into the target FPR FRT.
The fmr instruction has two syntax forms. Each syntax form has a different effect on Condition Register Field 1.
|Syntax Form||Floating-Point Status and Control Register||Record Bit (Rc)||Condition Register Field 1|
The two syntax forms of the fmr instruction never affect the Floating-Point Status and Control Register. If the syntax form sets the Record (Rc) bit to 1, the instruction affects the Floating-Point Exception (FX), Floating-Point Enabled Exception (FEX), Floating-Point Invalid Operation Exception (VX), and Floating-Point Overflow Exception (OX) bits in Condition Register Field 1.
|FRT||Specifies target floating-point register for operation.|
|FRB||Specifies source floating-point register for operation.|
