--- Comment #28 from Richard Biener <rguenth at gcc dot gnu.org> --- I tried to look up the requirements of __riscv_vle8_v_u8m2 in the vector intrinsic specs but besides listing all those intrinsics the spec doesn't contain _any_ documentation? The 2nd arg is named 'vl' which I interpret as vector length so that's so difficult for this intrinsic? Why isn't it just even a plain load? I read the specified 'vl' isn't exact but the intrinsics are still strongly typed, so a VLA typed gimple load should match here? And there should be a way to constrain the implementation somehow since 'arr' has limited size. Is the implementation constrained to use a vector length <= the specified 'vl'?
