| 50 | // - This version typically avoids using VNNI vpdpwssd instructions, opting instead for separate madd and add operations. | ||
| 51 | // - Masked permute operations are not optimized: for example, instead of using masked permutex2var_epi8, | ||
| 52 | // it performs a basic permutex2var_epi8 followed by an "and" with a pre-loaded zmm mask. | ||
| 53 | // These behaviors result in slower code compared to MSVC builds, which utilize these instructions more efficiently. | ||
