--- Comment #21 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
CCing some maintainers, could you please consider adding these
uaddc<mode>5/usubc<mode>5 expanders to rs6000, aarch64, arm, s390, riscv
targets if the targets have some appropriate instructions (add with carry and
subtract with carry/borrow), copy the above gcc.target/i386/ testcases to other
gcc.target subdirectories and verify there you get optimal code for those
sequences?
The _BitInt addition/subtraction code will also use these new internal
functions if possible, so implementing it will also help get usable code for
_BitInt later on.
