Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |krebbel at gcc dot gnu.org, | |law at gcc dot gnu.org, | |rsandifo at gcc dot gnu.org, | |segher at gcc dot gnu.org --- 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.
