linux core support

linux core support

[more]

I am using the GNU tools for the arm linux platform, the tools are so 
wonderful, thanks for all the men who pay their effort on it.

When I use the cross gdb for the linux arm platform, I am a little puzzled 
that it does not support core file, even the native arm linux gdb seems not 
too. It seems that only the i386 native gdb support the core dump file for 
linux. I think the integration work for all the linux platform( either native 
or target) the core file support is at hand, cause gdb has a file gregset.h 
to assist it, does anyone take effort on it?


Regards,
more.

That's not quite right.  I believe that ARM core files work natively on
arm-*-linux; I've used them.  Cross gdb does not currently support
cores, for Linux targets at least; I have patches in progress to change
that.

You are sure it supports elf format elf dump file? Until now I have no chance 
to try the native arm linux gdb. Cause when I study the insight source, it 
seems not, Maybe I am not examining the source in patient, thanks for your 
feeding.

Greatly thanks for your help, I will manage to do that.

If the native build already has all the necessary files, reshuffling
is good enough; otherwise, you may have to provide your own.

For ELF and other file formats, check
