Core Register Summary
1
6.3
The following sections describe general-purpose and integer exception registers.
6.3.1
GPR0–GPR31 support integer operations. The instruction formats provide 5-bit fields for specifying the
GPRs to be used in the execution of the instruction. Each GPR is a 64-bit register, although only 64-bit
load, store, and merge instructions use GPR bits 0–31.

Accesses to this register requires synchronization, as described in the “Synchronization Requirements” section of the
“Register Model” chapter of the PowerPC™ e500 Core Family Reference Manual .
