--- Comment #4 from Steven Munroe <munroesj at gcc dot gnu.org> --- (In reply to Kishan Parmar from comment #3) > Given the above context, is there a technical or architectural reason to not > add builtins for the POWER9 decimal/BCD instructions, or should they be > implemented simply to expose existing hardware support?

If builtins are provided for BCD ops defined in PowerISA 2.07 its seems natural to also provide builtins for the new BCD and multiply by 10 ops added for PowerISA 3.0. For the C programmers converting vectors between Zone/BCD/Binary formats they are useful.
