Sorry, I was not aware of this patch. Since Jeff's patch was here first and also includes more tests, I propose to move forward with his patch (but I'm not a maintainer!). Therefore, I've reviewed Jeff's patch and replied to his email.FWIW: Jeff's patch can be found here: https://gcc.gnu.org/pipermail/gcc-patches/2023-June/622233.html
No problem. And I would tend to remove the D03 constraint if we used const_0_3_operand. BR Liao Shihua
