I'm not sure that's necessary. DFP enablement isn't triggered by
assembler support. Just the gcc/configure fragment (ignoring manually
using --enable-decimal-float):
case $target in
powerpc*-*-linux* | i?86*-*-linux* | x86_64*-*-linux* | s390*-*-linux* | \
i?86*-*-elfiamcu | i?86*-*-gnu* | x86_64*-*-gnu* | \
i?86*-*-mingw* | x86_64*-*-mingw* | \
i?86*-*-cygwin* | x86_64*-*-cygwin*)
enable_decimal_float=yes
;;
*)
{ $as_echo "$as_me:${as_lineno-$LINENO}: WARNING: decimal float is not
supported for this target, ignored" >&5
$as_echo "$as_me: WARNING: decimal float is not supported for this target,
ignored" >&2;}
enable_decimal_float=no
;;
So I don't think there is anything to do wrt Darwin here.
