The wcc test drivers ran `ww build <bare-/tmp src>` with no -o, so the compiler's <stem>.sepwork scratch landed beside the source and was never cleaned: unbounded /tmp growth (2195 stale dirs observed) that fills tmpfs and fabricates phantom test failures + silent harness aborts, and for in-repo fixture builds leaked .sepwork into the tracked tree. Each leaking build now writes its source + output inside a per-invocation tmpdir, passes -o <tmpdir>/<stem> so the .sepwork lands inside it, and rm -rf's the tmpdir on every exit path -- including fopen-fail and the expected-fail reject builds (scratch is mkdir'd before the build can fail). `ww run` and explicit-`-o`/byte-id helpers are left as-is; the 990/993 byte-id comparison logic is byte-for-byte unchanged. Two items filed separately (this commit holds the no-Makefile / no-main.c rail): - #13: a stale <src>.s byte-id readback (749) silently no-ops since separate-compile emits .s to <ostem>.sepwork/__root.s; documented inline. - #14: build-system Makefile recipes build selfhost/cmd/*/main.ww with no -o and leak main.sepwork in-tree (bounded, gitignored; own commit). One concern -- sepwork leak hygiene -- across 228 drivers; uniform transform applied per-file and two-round reviewed. make test: all 402 passed, zero net-new /tmp scratch, zero test-driven in-repo .sepwork.

* 944_alias_global_decl_run — g-fold (#77 + #78 fused): alias-typed
|
|
* GLOBAL declarations, both stages. The decl/emit dispatch was
|
|
* alias-blind on both sides:
|
|
*
|
|
* cs (#78): the let_* helper family (let_emit_size + the five kind
|
|
* predicates, cgen.c) single-peeled — a 2-level alias chain (or ONE
|
|
* user alias over a named struct) left the type TY_NAMED, so the
|
|
* global was never registered, no DATA was emitted, and reads fell
|
|
* to the frame-local path at offset 0: silent saved-BP reads (garr2
|
|
* exit-wrong, gst1 SEGV, gstr2/gsl2 silent-wrong). The routed-to
|
|
* DATA emitters re-peeled at entry and return-0'd into the silent
|
|
* skip (condition-3 members, enrollment ruling in
|
|
* .ai/rob-gfold-spec.md).
|
|
*
|
|
* ww (#77): emitletdataw's array gates + letpreintern's array leg
|
|
* keyed on the UNCHASED N_TARRAY tnode — an alias-typed global's
|
|
* N_TNAME matched no arm and the skip-policy ate the decl: loud
|
|
* `w6l: undefined reference to main.g` on every alias-global ARRAY
|
|
* row. Fix: ONE tichase at the dispatch entry (dti), array gates +
|
|
* emitarraydata read it.
|
|
*
|
|
* THIS TABLE IS THE PERMANENT GUARD, not scaffolding: the global decl
|
|
* path is lint-invisible to the future peellint — the ww side was a
|
|
* NO-PEEL consumer (zero `.under` tokens; nothing for a peel-shape
|
|
* lint to flag), and the cs helpers now spell the one chased accessor.
|
|
* Only a runtime+byte-id row pins this behavior.
|
|
*
|
|
* Train trajectory (two commits, one gated train; per-leg states were
|
|
* probe-verified, banked /tmp/implG_probes.md):
|
|
* pre-G1: garr2 cs EXIT-WRONG / gst1 cs SEGV / gstr2+gsl2+gstlit cs
|
|
* silent-wrong / gsc2+gflt2 cs loud / ww array rows link-ERR
|
|
* post-G1 (cs half): every cs row runs 0; ww array rows STILL
|
|
* link-ERR (loud, documented)
|
|
* post-G2 (ww half): every row 0/0 byte-id — this file's assertion.
|
|
*
|
|
* Probe-OUT, documented NOT pinned (failed at a DIFFERENT site, filed):
|
|
* named-tuple global init — cs checker loud-reject, ww accepts (#86)
|
|
* plain tagged global — cs silent-wrong, ww loud-reject (#87, not
|
|
* alias-family; control row fails)
