gdb multiarch

[Matwey V. Kornilov]

Hi,

What is about enabling multiarch support for gdb? I think it would be
useful especially for debugging remote targets.

At least, may we add gdb-multiarch package with --enable-targets=all
configure options?

What do you miss from the existing multitarget support?

I mean, at x86_64 gdb I have:

(gdb) set architecture
Requires an argument. Valid arguments are i386, i386:x86-64,
i386:x64-32, i8086, i386:intel, i386:x86-64:intel, i386:x64-32:intel, auto.

It would be great to have also arm here to use with target remote.

How did you do that?

I run opensuse 12.3

You can install the newest GDB from the gdb devel project, devel:gcc

This is opensuse-factory@, you shouldn't come here with something that
old. :-)
