            Bug ID: 38343
           Summary: clang doesn't emit masked instructions from 256-bit
                    AVX512VL mask intrinsics
           Product: new-bugs
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: new bugs
          Assignee: unassignedbugs at nondot.org
          Reporter: hdevalence at hdevalence.ca

Although the `mask_add256_avx512vl` function uses a mask intrinsic, it produces
the same code (and I think the same IR) as the `mask_add256` function, which
doesn't. (I wasn't able to get clang to emit masked ymm instructions at all).
