[PATCH 0/3] Fix fails in gdb.mi on arm-none-eabi

[Yao Qi <yao at codesourcery dot com>]

Hi,
This series fixes some fails in mi-var-child.exp and
mi-var-display.exp, which are caused by printed symbol on address
zero.  One of them is fixed by "set print symbol" off, and that is
what patch 1/3 does.  Patch 2/3 is a refactor patch, which uses
mi_varobj_update in tests to simplify them.

The cause of the rest of fails is that function pointers are NULL,
and they point to a code symbol _ftext on address zero.  We can
relax pattern to match both "0x0" and "0x0 <_ftext>", but I didn't
fix it in this way.  Instead, I explicitly assign function address
to these function pointers, so the output becomes "$hex <$func_name>"
on all the targets.  See details in patch 3/3.

The patch series is tested on x86_64-linux with native and gdbserver,
and arm-none-eabi.
