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: [email protected]
Reporter: [email protected]

Test case here:
https://godbolt.org/g/6apogL
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).
