PowerPC Instruction Set

3.3.1.1 PowerPC Instruction Set
The PowerPC instructions are divided into the following categories:
• Integer instructions—These include computational and logical instructions.
— Integer arithmetic instructions
— Integer compare instructions
— Integer logical instructions
— Integer rotate and shift instructions
• Floating-point instructions—These include floating-point computational instructions, as well as
instructions that affect the FPSCR.

— Floating-point arithmetic instructions
— Floating-point multiply/add instructions
— Floating-point rounding and conversion instructions
— Floating-point compare instructions
— Floating-point status and control instructions
• Load/store instructions—These include integer and floating-point load and store instructions.
— Integer load and store instructions
— Integer load and store multiple instructions
— Floating-point load and store
— Primitives used to construct atomic memory operations (lwarx and stwcx. instructions)
• Flow control instructions—These include branching instructions, condition register logical
instructions, trap instructions, and other instructions that affect the instruction flow.
— Branch and trap instructions
— Condition register logical instructions
• Processor control instructions—These instructions are used for synchronizing memory accesses
and management of caches, TLBs, and the segment registers.
— Move to/from SPR instructions
— Move to/from MSR
— Synchronize
— Instruction synchronize
• Memory control instructions—These instructions provide control of caches, TLBs, and segment
registers.
— Supervisor-level cache management instructions
— User-level cache instructions
— Segment register manipulation instructions
— Translation lookaside buffer management instructions
