--- Comment #8 from Raghesh Aloor <raghesh.aloor at amd dot com> --- We have posted an RFC [1] and an initial prototype for Phase 1 of that design [2], aimed at this bug (predicated pack index + masked store, toward AVX-512 compress/expand-style vectorization). Richard suggested building on the existing vectorizer path that treats some .MASK_STORE cases as scatter (and related strided-store handling) when data-reference analysis cannot describe the address. We are exploring that direction alongside the RFC’s phased plan. [1] https://gcc.gnu.org/pipermail/gcc/2026-May/248167.html [2] https://gcc.gnu.org/pipermail/gcc-patches/2026-May/716654.html
