Depending on the DejaGNU board definition, the .gnu.sgstubs section
might be placed on different locations in order to suite the target.
With this patch, the start location of the section is overrideable
from the board definition with the fallback of the previously
hardcoded location.
gcc/testsuite/ChangeLog:
* gcc.target/arm/cmse/bitfield-1.c: Use overridable location.
* gcc.target/arm/cmse/bitfield-2.c: Likewise.
* gcc.target/arm/cmse/bitfield-3.c: Likewise.
* gcc.target/arm/cmse/cmse-20.c: Likewise.
* gcc.target/arm/cmse/struct-1.c: Likewise.
* gcc.target/arm/cmse/cmse.exp (cmse_sgstubs): New.

Hi Torbjörn,
This looks like a nice improvement to me ;-)

I am not sure if/where this new cmse_sgstubs target-board property needs
to be documented?

I'm not sure either. Everytime I need to do something with the
target-board properties, I just look at other examples in the tree and
replicate what they do.
I'm also not sure if "cmse_sgstubs" is a good name, but I was unable to
come up with a more meaningful name that was not a mile long... If there
is any sugession on a better name, please speak up! :)
Kind regards,
