--- Comment #1 from Michael Meissner <meissner at gcc dot gnu.org> ---
In addition to __floatdiif not being in libgcc, if you build a recent trunk, it
exposes a second issue:
-ltcden3-lp5-> /home/meissner/fsf-install-ppc64le/trunk/bin/gcc -O2 pr-104253.c
during RTL pass: expand
pr-104253.c: In function ‘main’:
pr-104253.c:8:9: internal compiler error: in copy_to_mode_reg, at explow.cc:652
8 | printf("%a
%a\n",__builtin_unpack_ibm128(i,0),__builtin_unpack_ibm128(i,1));
