Description
Umbrella ticket for various PMADDWD/PMADDUBSW codegen issues (and indirectly VNNI instructions)
Contributor guide
Research direction
Start by reviewing the PMADDWD and PMADDUBSW codegen issues covered by this umbrella ticket, including their indirect relationship to VNNI instructions. The issue does not name files, tests, or an entry point, so completion criteria must be established by breaking the umbrella scope into specific codegen tasks.
