powerpc disassemble instruction by its raw data

Question

How can I disassemble some intructions from memory dump? I have only raw dump, objdump understands only object format.

My processor is PowerPC 440 (PowerPC Book E Architecture).

Answer 1

In fact, objdump can disassemble raw binary just fine. Try this:

objdump -m ppc -D -b binary -EB dump.bin

Answer 2

$ xxd -p asm
3800000060000000

Using devkitPPC:

$ powerpc-eabi-objdump --disassemble-zeroes -m powerpc -D -b binary -EB asm

Yields:

asm:     file format binary

Disassembly of section .data:

00000000 <.data>:
   0:   38 00 00 00     li      r0,0
   4:   60 00 00 00     nop
