Strlit labels were emitted as `_S_<n>` from a global counter with no per-unit prefix (cgen.c intern_strlit + wwstage internstrlit twin). Under separate compilation two str-bearing packages both emit `_S_0`.. -> w6l link collision. Prefix the label with the owning package PATH (`<module>._S_<n>`, matching mklabel's spelling). The prefix is c->cur_mod, set per-fn by cgfn and now per-decl by let_pre_intern (save/restore so the later emit passes, which read cur_mod for fn-ptr relocs, are unaffected). Pure function of the module path — NOT a build-nonce — so the self-host fixed-point holds across ww2/ww3/ww4. Both stages, symmetric. Transparent rename on the live combined path: the label is interned once and shared by every reference, so ref and def move in lockstep. cs==ww byte-id holds; the w6c/wwdump combined.ww embed wcc/cgen.ww and are regenerated. 746_strdef_inline: the strdef-inline sentinel pinned the bare `LEAQ\t_S_` shape; update to the module-prefixed form (alpha._S_ for the in-module def, beta._S_ for the use-site-interned cross-module inline). 989_m3sep_run: add the #49 LINK leg. The str sub-fixture (sleaf+smid) was keystone-only — never linked — precisely because the global counter made both emit `_S_0`. With the prefix, compile both `-c` separately, link (w6l) + run (sroot reads a distinguishing byte through each string's .ptr, so a collided label would corrupt the exit), both stages + cs==ww final exe.

/*
|
|
* 989_m3sep_run — M3 `.wwi` separate-compilation CONSUMER gate (task #22 arc).
|
|
*
|
|
* M3 = w6c `-c` (separate-compile / primary-only codegen) reads each imported
|
|
* package's `.wwi` prototypes (M2's producer output) as import scope INSTEAD of
|
|
* re-checking dep bodies. Pure addition: combined.ww stays the LIVE path, `-c`
|
|
* is off on every existing invocation. This gate certifies the consumer.
|
|
*
|
|
* Fixture: a leaf -> mid -> root chain carrying ALL FOUR cross-boundary fact-
|
|
* classes — fn SIGNATURE (leaf.add), struct/type LAYOUT (leaf.Point, used as a
|
|
* by-value param + returned), `def` const VALUE (leaf.SCALE, const-folded into
|
|
* mid), and `export let` value-global (leaf.origin_tag, read across the
|
|
* boundary). mid imports leaf; root imports both.
|
|
*
|
|
* THE LOAD-BEARING CLAIM (rob §4.1): compiling package P in sep mode (deps as
|
|
* `.wwi`) produces the SAME codegen for P's own symbols as compiling P with
|
|
* deps as full BODIES — proven by holding the `-c` codegen FILTER constant and
|
|
* varying ONLY the dep-source form:
|
|
* Pbodies.s = w6c -c (deps as //ww:module body sections + P)
|
|
* Psep.s = w6c -c (deps as //ww:module .wwi sections + P)
|
|
* GATE: cmp Pbodies.s Psep.s → byte-identical (per-package, sharp blame).
|
|
* Both emit ONLY P's symbols (the `-c` filter), so the cmp proves the `.wwi`
|
|
* conveys exactly the type/layout/const facts the dep bodies did, for P's code.
|
|
*
|
|
* Plus, per package: the keystone on BOTH stages (cstage bodies==sep and
|
|
* wwstage bodies==sep — so a wwstage-only guard regression can't hide behind
|
|
* the `.wwi`-sourced sep unit), cs==ww at the `.s` level (rule 10 — w6c vs
|
|
* w6c_ww on the identical sep-unit), sep-path determinism (compile twice ->
|
|
* identical), and the value-global guard (an imported `export let` must NOT
|
|
* re-emit DATA — that would duplicate the dep's own definition -> link
|
|
* collision). A str sub-fixture (sleaf -> smid -> sroot) makes the strlit-
|
|
* intern guard non-vacuous AND, post-#49 (per-unit `_S_` prefix), LINKS the
|
|
* two str-bearing packages without a label collision — see its note below.
|
|
* End-to-end:
|
|
* compile each package's .o under `-c`, link with w6l, run -> exit code is the
|
|
* real cross-boundary computation; the SAME with the wwstage tools (w6c_ww/
|
|
* w6a_ww/w6l_ww) -> cs==ww at the final-exe level + behavioral identity.
|
|
*
|
|
* COLD: a fresh getpid-keyed /tmp dir, `.wwi` materialized from scratch every
|
|
* run (no warm cache — a stale `.wwi` is a #110-class freshness hazard). No
|
|
* source-tree writes -> phase-1 parallel-safe. 9xx is full; shares the 989
|
|
* prefix per the 989_lib_byteid / 989_m2wwi precedent (the short name keys the
|
|
* binary). Models 989_m2wwi_run.c conventions.
