--- Comment #3 from nsz at gcc dot gnu.org --- (In reply to Ramana Radhakrishnan from comment #2) > A simple patch would be to check for __ARM_FEATURE_SAT in all those macros > in exch_n.c along with HAVE_STREXB etc .. __ARM_FEATURE_SIMD32 seems to be the right feature test macro, (_SAT is defined on armv7-m) and with that libatomic compiles.
