| stdux | RS, RA, RB |
The stdux instruction stores a double-word in storage from the source general-purpose register (GPR) RS into the location in storage specified by the effective address (EA).
The EA is the sum of the contents of GPR RA and RB. GRP RA is updated with the EA.
If rA = 0, the instruction form is invalid.
| RS | Specifies the source general-purpose register containing data. |
| RA | Specifies source general-purpose register for EA calculation. |
| RB | Specifies source general-purpose register for EA calculation. |
This instruction is defined only for 64-bit implementations. Using it on a 32-bit implementation will cause the system illegal instruction error handler to be invoked.
