--- Comment #1 from nsz at gcc dot gnu.org ---
building a cross compiler with --with-mode=thumb --with-arch=armv7 fails with
/tmp/ccCnEnAK.s:61: Error: selected processor does not support `uadd8 r3,r3,r3'
in Thumb mode
/tmp/ccCnEnAK.s:63: Error: selected processor does not support `sel r3,r1,r4'
in Thumb mode
because the asm in
libatomic/config/arm/exch_n.c
is not compatible with armv7-m.
