Hi,
After a much needed rebuild of the server running various GDC-related hosted services [http://forum.dlang.org/post/zrnqcfhvyhlfjajtqebt@forum.dlang.org] - I've gotten round to updating the compiler disassembler.
http://explore.dgnu.org/
Now supports 12 different architectures from ARM to SystemZ! (not including -m32 or any -march options)
Enjoy.
Iain.
