I'm trying to disassemble the csky processor code, the processor is 32-bit, with 32-bit V2 instructions, but objdump outputs data and code as 16-bit, how can I force it to output in 32-bit?

You *might* be able to achieve this using objdump's -m command line option.

For example:

   objdump -m csky:ck801 -d <file>

The list of csky architecture types supported by objdump are listed in its --help output.

When I call to objdump -x exefile ...
Does it give the calls within the exefile to the DLL functions or it lists
the functions related to each DLL ?
If it supplies the functions within each DLL, how do I use the objdump to
supply the functions within the executables which call functions of a
certain DLL ?

Thanks,
Clint

This is an old version of objdump.  Please could you try the latest
version (2.11.2) to see if the problem still persists there.

Hi,

: Can you some direct me in the direction of the person who deals with
: objdump -d for mips arch using a linux machine as a host.

You can post your questions to this list.  It is read by the MIPS
maintainer and a lot of other people who are also interested in this
tool.

Cheers

Hello

I have recompiled the binutils 2.9.5.29 for target=mips32 to enable me
to dissasm some ps2 elfs as part of my University research.

I am however interested in if it will suport the r5900 cpu as atm it
identifies the cpu as r4400 which is similar but does not have the
128bit instructions i think


does any one know if some one is working on a r5900 version?
