Load a double-word from a specified memory location into a general purpose register.
|ldx||RT, RA, RB|
The ldx instruction loads a double-word from the specified memory location referenced by the effective address (EA) into the general-purpose register (GPR) RT.
If GRP RA is not 0, the EA is the sum of the contents of GRP RA and B; otherwise, the EA is equal to the contents of RB.
|RT||Specifies target general-purpose register where result of operation is stored.|
|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.
