From PR #329 (stacked on #328): a game's usage manifest, dm/games/<id>/usage.tsv,
written by its owner with regress.py usage (shader features of its chain build,
and the NVN / HLE functions, SVCs and present path of one smoke-route run;
names and counts only), and regress.py impact <base>..<head>, which maps the
functions around the changed lines through the host's callers and the rules of
dm/tools/impact_map.tsv to manifest rows. Manifests for Breath of the Wild,
Tears of the Kingdom and Hades.
Fixed on top of the PR:
- impact checked the head out as a git worktree under the harness root, so it
stopped (PermissionError on /Volumes/NX) for exactly the contributors it is
for, who have no games and no harness root. The call graph is now read from
the git object store at the head revision, and the report is printed and
written only to --out or an existing harness root.
- A hunk mapped only to the function at its first line: a hunk spanning two
functions named one. Every added line is mapped now, and a pure deletion maps
to the function around it (it was moved one line up).
- Functions defined in headers were not in the call graph: the frame step
(nvn_fstep.h, static inline, called from nvnQueuePresentTexture) reached no
entry point, so 4acde72 named no game. Headers are scanned, and their
functions are visible to every file. 4acde72 now names both Zeldas through
nvnQueuePresentTexture.
