Analyzing the PowerPC 604
Using the Inverse Assembler
The Extended dialect adds several extended opcodes for the rotate
instructions. For example, the function of the rlwirnn instruction
rlwinm r30 r30 16. 16. 31.
is to shift right word immediate, eg
srwi r30 r30 16.
The following listing shows the extended mnemonics for the integer rotate
instructions.

PowerPC assemblers support a number of extended mnemonics for some
popular assembly language instructions as described in the PowerPC
Architecture. The HP E2465A disassembler supports the following
extensions of dialect-sensitive instructions.
