--- Comment #117 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Note I am opening a bug report per target for BitInt support and linking to PR 117580 . e.g. PR 117581 for RISCV, PR 117582 for arm, PR 117583 for big-endian aarch64 and PR 117584 for PPC. I think this bug report should be closed as fixed for GCC 14 then.
