Hi Markus,

> Compile an empty source-file (I.e. empty.c) with:
>arm-eabi-gcc -c -mabi=apcs-gnu empty.c
>arm-eabi-readelf -a empty.o
> will show the .ARM.attributes section (type ARM_ATTRIBUTES) with a

Well I tried this using the FSF GCC and binutils mainline sources and the
problem did not occur - ie the object file contains the correct attributes and
readelf does not complain.  I have uploaded a copy of the object file for you
to examine if you wish.

My guess is that this is a bug which has already been fixed, some time after
2.25 was released.  Since it is a minor problem I am not going to search for
the patch and backport it to 2.25, unless you can convince me otherwise.

Cheers
  Nick
