--- Comment #7 from Sebastian Huber <sebastian.hu...@embedded-brains.de> ---
It seems to be a general problem with -msoft-float on PowerPC64. I built a
native GCC on gcc112:
[sh@gcc2-power8 ~]$ cd /home/sh/b-gcc-git/gcc/ada/rts
[sh@gcc2-power8 rts]$ gdb --args /home/sh/b-gcc-git/gcc/gnat1 -gnatwa -quiet
-nostdinc -nostdinc -dumpbase a-coteio.ads -auxbase-strip a-coteio.o -O2
-Wextra -Wall -g -gnatpg -msoft-float -gnatO a-coteio.o a-coteio.ads -o -
