test: port the sep-layout observers to ww; retire 989_{sepbuild,seproot_export,sepstructdef,wwispread}

Browse Source 
Birth test/sep/ (single-file ww observers on test/testenv, run by the
new SEP_WW_TARGETS pattern rule under test-compiler) with
sepbuild_test.ww: the build_one_sep real-chain gate incl. the
bodies==.wwi keystone recompile, the #69 root-without--I contract, the
#70 aggregate-def .wwi prototypes, and the #95 spread-marker
round-trip. Every carrier assertion has a successor row; the C
cleanup-accounting ledgers collapse into testenv.clean.

// sepbuild (#46 commit-3) — build_one_sep END-TO-END on the real lib
// chain root -> os -> {rt,time} (transitive-closure discovery + topo):
// build+run exit 7 both stages; {time,rt,os}.wwi + __root.s
// materialize (#69: the root is compiled without -I, so no
// __root.wwi); per-package .s/.wwi/.unit.ww and the final binary
// byte-id cs vs ww; the KEYSTONE (spec 3.1) recompiles the driver's
// own non-leaf .unit.ww with each dep's .wwi section replaced by that
// dep's full directory bodies and requires byte-identical .s — the
// proof the .wwi conveys exactly the dep facts P's codegen needs;
// `ww run` routes through the same sole sep path (exit 7 both
// stages).
//
// seproot (#69 BUG-1) — a ROOT whose `export fn use(a: *t)` names an
// unexported local `type t` builds (exit 37 both stages) because the
// root is compiled WITHOUT the -I .wwi-producer flag: __root.wwi must
// NOT exist; replaying the driver's own __root.unit.ww through
// w6c/w6c_ww with -I must REJECT (the isolated bug) while -c -o alone
// must accept; __root.s carries the exported fn.
//
// sepstructdef (#70 BUG-2) — a dep exporting aggregate-init defs
// (struct-lit + array-lit) sep-builds and links (exit 20 both
// stages); d.wwi carries the value-LESS prototypes `export def info:
// s;` + `export def arr: [3]i32;` and NOT the value-serialized
// `export def info: s = ` form (the producer took the aggregate arm).
//
// wwispread (#95) — the `...` union-spread marker survives N_TTAGGED

* multi-level dep edge): root → os → { rt, time }. rt and time are
* true leaves; os imports both AND its public interface exposes a
* transitive type (os returns/takes time.instant in sibling protos), so
* the root's sep-unit needs the TRANSITIVE `.wwi` closure for name
* resolution — direct-deps-only does not type-check (the lead-ratified
* superseding of rob-c3-spec §1.3). The graph thus exercises:
* - discovery of the transitive package set,
* - reverse-topo dep-first ordering (time/rt before os before root),
* - the transitive-closure `.wwi` prepend tagged by dotted path,
* - one-pass `w6c -c -I` (consumer + producer) per package,
* - `w6l` of the root `.o`, dependency `.a` set, and libwwrt.a.
*
* Asserts (fresh output stems under an invocation-owned root; retained
* `<stem>.sepwork` is inspected, then removed by final carrier cleanup):
* 1. Build + run, BOTH stages → exit EXPECT_EXIT (cross-boundary
* os.getpid resolves across the root `.o` and dependency `.a` boundary;
* the program runs).
* 2. cs==ww (rule 10): per-package `.s`/`.wwi`/`.unit.ww` AND the final
* binary are byte-identical between `ww` and `ww_ww`.
* 3. KEYSTONE (load-bearing, §3.1) THROUGH the driver: for each non-leaf
* package P, transform the driver's own `<P>.unit.ww` by substituting
* each dep's `.wwi` section with that dep's full directory BODIES,
* `w6c -c` it, and cmp vs the driver's `<P>.s`. Byte-identical proves
* the `.wwi` conveys exactly the dep facts P's codegen needs. (Leaves
* rt/time have no deps → keystone is vacuous; checked on os + root.)
*
* All intermediates are `-o`-redirected to /tmp for isolation. Models
* 989_m3sep_run.c conventions; 989 prefix per the m3sep/m2wwi precedent.

/*
* 989_seproot_export_run — sep-build of a ROOT unit whose `export fn`
* references an unexported LOCAL type (#69, BUG-1).
*
* Root cause it guards: the separate-compilation producer compiled EVERY package,
* INCLUDING the root build-target, with the `.wwi`-producer `-I` flag.
* `-I` triggers wwi_emit -> check_exported_type, which rejects an exported
* declaration that references an unexported type. A terminal binary's root
* legitimately has such a decl (`export fn use(a: *t)` over an unexported
* local `type t`) — fine, because the root is never imported, so its `.wwi`
* is never consumed. Historically, the separately compiled root was also
* passed `-I`, so it rejected and blocked every real tool build.
* Fix: for pi==root the producer invokes `w6c -c -o` WITHOUT `-I`.
*
* Graph (smallest reproducing shape): root -> { c (one real dep package) }.
* The root exports `use(a: *t)` over the unexported local `type t`.
*
* Asserts (direct builds compile every package):
* 1. Build + run, BOTH stages -> exit EXPECT_EXIT. Pre-fix the root w6c
* pass exited 1 ("exported declaration references unexported type"),
* so the build never produced a binary.
* 2. cs==ww (rule 10): per-package `.s`/`.wwi`/`.unit.ww` for {c,__root}
* AND the final binary are byte-identical between the two drivers.
* 3. NON-VACUITY (forced -I reject): re-run the EXACT pre-fix root
* invocation on the produced `__root.unit.ww` — `w6c -c -I <wwi> -o`
* MUST exit non-zero (the export-check fires on this pattern), while
* `w6c -c -o` (the post-fix root invocation) MUST exit 0. Demonstrated
* for BOTH compilers (w6c, w6c_ww). This is the bug, isolated.
* 4. The root `.s` is produced and defines the exported fn symbol.

* All intermediates are `-o`-redirected to /tmp for isolation. Models

/*
* 989_sepstructdef_run — sep-build of a dep package that EXPORTS aggregate-
* initializer defs: `export def info: s = s{a=7,b=11};` (N_STRUCTLIT) and
* `export def arr: [3]i32 = [1,2,3];` (N_ARRLIT) — BUG-2 (#70).
*
* Root cause it guards: the `.wwi` producer's const-expr emitter handled
* scalar/N_BIN/N_UN/N_DOT but NOT N_STRUCTLIT(15)/N_ARRLIT(16). An exported
* aggregate-init def aborted the producer with "unhandled const-expr node
* kind 15", so the dep never produced a `.wwi` and the sep-build failed.
*
* Fix (producer, both stages): an aggregate-init def is a DATA-global (#52),
* so the producer emits a value-LESS prototype `export def X: T;` — the
* defining package's own `.o` emits the struct/array DATA; the importer
* registers the def by TYPE only (cgen's emit_defs/emit_lets already skip a
* NULL-rhs def, no dup DATA) and reads resolve to external refs the linker
* fills. Consuming the prototype also required the def parser (both stages)
* to accept the bodyless form, mirroring the existing fn-prototype arm.
*
* Graph (smallest reproducing shape): root -> { d (one real dep package) }.
* d exports an aggregate STRUCT def (info), an aggregate ARRAY def (arr),
* and three reader fns; root sums them at RUNTIME.
*
* Asserts (direct builds compile every package):
* 1. Build + LINK + run, BOTH stages -> exit EXPECT_EXIT. The link+run is
* the external-DATA-ref proof: the importer's CALL d.geta / d.getelem /
* d.getb and d's own LEAQ d.info/d.arr(SB) refs resolve against the dep
* `.o`. Pre-fix the dep producer aborted ("node kind 15") -> no binary.
* 2. cs==ww (rule 10): per-package `.s`/`.wwi`/`.unit.ww` for {d,__root}
* AND the final binary are byte-identical between the two drivers.
* 3. The dep `.wwi` carries the value-LESS prototypes `export def info: s;`
* and `export def arr: [3]i32;` (the fix's surface), and NOT the old
* value-serialized `export def info: s = ` form (NON-VACUITY: proves the
* producer took the new aggregate arm, not the scalar arm).
*
* All intermediates are `-o`-redirected to /tmp for isolation. Models
* 989_seproot_export_run.c conventions; 989 prefix per the sep-gate precedent.

/*
* 989_wwispread_sep — #95 .wwi producer must preserve the `...` union-spread
* marker when serializing a tagged-union type under `ww build`.
*
* A spread variant `(...inner | str)` carries Node.op == TK_ELLIPSIS on the
* variant node (parse.c:315-324). The N_TTAGGED serializer loop must re-emit
* the `...` prefix purely syntactically (cstage wwi.c, selfhost wwi.ww) —
* mirroring Hare's unparse (ref/hare/hare/unparse/type.ha:290-300), which
* leaves flattening to the consumer's type-store. Before the fix the marker
* was dropped: liba.wwi read back as `(inner | str)`, a consumer never
* flattened inner's arms, and a bare i32/i64 member was rejected — so fmt /
* log / getopt failed under the sep flip. (The old combined.ww path never
* round-trips through .wwi, so it accepted; the bug was latent until the flip.)
*
* TABLE-DRIVEN over two spread shapes (2-arm `inner` and 3-arm `three`). For
* each shape and each driver stage (cs `ww`, ww `ww_ww`) the test:
* (a) builds the consumer via `ww build` and runs it — clean compile
* + exit 0 proves the imported alias's arms flattened into the spread
* type (the consumer assigns BARE members the spread must expose);
* (b) greps the produced <pkg>.wwi and asserts the spread marker survived;
* (c) cs==ww (rule 10): the .wwi from `ww` vs `ww_ww` must be byte-identical.
*
* NON-VACUITY: reverting the wwi.c/.ww edit reddens BOTH legs — the consumer
* build fails with `init i32 not assignable to declared outer` AND the marker
* grep finds nothing (verified by hand at fix time).
*
* Every build's intermediates are `-o`-redirected to a private /tmp directory.
* Models 989_declns_sep conventions; 989 prefix per the sep-gate precedent.
