Overview
Move the Q6 row-range compiler hint from the shared reader to the tiled prefill caller. This preserves the shared reader's decode code generation while retaining the tiled-prefill optimization.
This is fix 5/5 in the row64 stack following #181. Stacks on #190; base branch:
users/astgeorg/row64-q4-tile-coordinates. Commit:bd85479285423b239213519d0892c56d071864df. Keep each fix as a separate stacked PR.Validation
Independent review found no blocking source issues. The committed build and four representative controls passed. Inspected Q4/Q6 decode assembly and machine code match the shared-reader control; inspected Q4/Q6 prefill code matches the preceding commit. Addresses, dequantization arithmetic, layouts and matchers are unchanged.
The complete stack at
bd85479285423b239213519d0892c56d071864dfwas measured against frozen integrationbe335351871563a09520b0db4a63c21db2040807with standalone llama-bench. The final fifteen-model table and separate Qwen3-0.6B stability result are in #181; those combined-stack results are not isolated gains from this commit.Requirements
