lib/strconv/test/ was the last _test layout deviating from Go's
in-package shape (src/bytes/bytes_test.go declares bytes_test in the
package dir). Its rationale — `import strconv` file-hitting the
sibling strconv.ww — dissolved when #98 made directory packages win
over same-named files on any search entry. libbyteid re-paths the
three fx entries and drops the covered() carve-out: the completeness
scan now keys lib/strconv through the fixtures' dirname. Walk line
flips to "ok lib/strconv [strconv_test, external]".
Unblocked by the package-mode ruling: same-package test files now
compose everywhere (coordinator dir-mode owns test-library and the
libbyteid dir entry owns byte identity), so the per-file standalone
constraint is gone and Go's stdlib layout applies directly. The
15-banner strings_test.ww monolith dissolves into per-ref-file
family files — dup, concat, trim, sub, utf8, iter, tokenize
(tokenize+splitn+cut, all of ref tokenize.ha), pad, replace — plus
helpers_test.ww holding exactly the one cross-family helper (streq),
Go's shared test-helper idiom. Pure moves; family-local helpers
(expect_str_token et al.) stay in their family file. Leading banners
that merely restated the filename dropped; 6 interior sub-family
boundaries remain. lib/ census 141 -> 132.
libbyteid gains the dx() dir-mode entry form decided in B2: compose
every *_test.ww under moddir exactly as pkgcombined does
(module-reset separators, byte-lex order) and byte-id the composed
root through both driver stages. The five per-file strings fx
entries retire into one dx("lib/strings") — every source line they
covered is inside the composed unit, and the completeness scan still
keys the module. NENTEXPECT 60 -> 56.
Recorded, not split: fmt_test's 13 banners are scenario groups over
the one fprint surface and ref/hare/fmt itself keeps a single
+test.ha — a print/wrappers split would fight the ref; memio stays
per the standing ruling (everything ww ports lives in ref
stream.ha).
Go has no per-file test targets: the PACKAGE is the unit of testing
(`go test ./...`) and same-package test files compose together. The
59-target LIBRARY_TESTS fan-out (per-file -w workdirs, one Make rule
per suite) collapses to one line: `ww test -j $(JOBS) -w
out/wwbuild/wwtest-lib -I lib/ww lib/...` — the regex dir-route
precedent generalized. The lib/regex line and the per-file pattern
rule instance dissolve with it (test/lang keeps its own rule).
Measured before committing (-j4, strings edit row): old per-file
warm 4.7-4.9s; bare walk 5.2-5.6s — a real regression, so the
coordinator first gained the brief's persistent per-package workdir:
`-w DIR` on a package target forwards to wwpackage, which keys
DIR/<dir>_<pkg> per group and hands it to each inner `ww test -c`
build. Reuse stays entirely with the driver's existing
content-identity contract — the coordinator adds pure path policy,
no cache machinery. Both driver stages drop their package-target -w
rejects (forward instead); -w with -c stays rejected at the
coordinator (two ownership contracts). After: 3.9-4.0s on the edit
row, 1.0s warm no-op, 2.5s cold — faster than the old flow on every
row.
package_test's tree -w reject row becomes the positive contract
(cold+warm byte-stable stream, cs/ww same) plus the -c conflict
reject. libbyteid roster shape DECIDED: per-file fx entries stay —
every enrolled file is still standalone-buildable, so coverage is
byte-for-byte unchanged; the dir-mode entry form arrives only with
the B3 shared-helper split that first needs it. Docs: owner table,
target table, -w contract paragraph.
Go does not distinguish bootstrap observers from unit tests: an
in-process test is a unit test. 738 is pure parsefile calls (arena +
lexinit + parserinit, AST assertions, zero subprocess or artifact
claims) — the 200_parse class, misfiled among the residuals. The
fleet partition now reads six units / six bootstrap / three platform
and the residual class is empty; COMPILER_WRAPPER_SOURCES drops it
by the existing filter-out. Doc roster updated (also refreshes the
corpus prose to the current 1745/3490 pin and retires the stale
794-era paragraph).
The bbdd8bed residue, ruled by the Go derivation (ww's for IS the Go
for; the cstage grammar is the language definition and already the
Go-shaped one):
- bare `for { }` accepted (align UP to parse.c:1023, incl. for-else);
- 3-clause cond and post each omissible — `for (init;; post)`,
`for (init; cond)`, `for (init;)` (align UP, parse.c:1092-1097);
- 2-clause `for (cond; post)` REJECTED (align DOWN): the form exists
in neither Go nor cstage (parse.c:1101 eats a stray ';' then
requires ')'), so the old wwstage accept was a parser bug. The
reject wording mirrors cstage's failure mode per stage.
forhdr_{brace,emptymid,partial} run fixtures pin the accepted forms
byte-identically; forhdr_twoclause_reject pins both reject fragments.
Corpus pin 1745/346/21/209/1169/3490.
A module-scope let whose rhs runs code (alloc, call — peeled through
cast/?/! wrappers) emitted no DATAW slot: emit_lets' fold-fail
silently skipped the definition and every reference died at LINK
time with 'undefined reference', the one unacceptable failure mode
(rule 7). Hare's model rejects at check time (ref/harec/src/
check.c:4360 'Unable to evaluate initializer at compile time') and
routes runtime init through @init, which ww does not have — so both
frontends now reject at the declaration with identical wording.
alias_infptr_global flips compile->error as the alloc pin (its
letvartnode N_TPTR-over-N_TSTRUCT coverage lives on in the local
alias_infptr_{nest,slicecap} siblings); callinit_global_reject pins
the call shape. Corpus pin 1741/345/21/209/1166/3482.
The two loud siblings filed in d3822d77: (a) an auto-deref *[N]T
indexed base (hs[k].result) failed cgplaceaddr's N_INDEX arm, which
knew only TY_SLICE/TY_ARRAY bases — add the one-pointer hop (the
(*hs)[k] form made implicit; load shape is the slice .ptr word's);
(b) a bare slice-element aggregate source (use(sl[k])) fell off
aggarg_srcaddr's ident-array-only N_INDEX arm into the #271 loud
stop — route the miss through the same cgplaceaddr fallback the
N_DOT arm uses. Both stages, byte-identical (probe matrix: let-copy,
field-assign, call-arg, return, indexed-store all IDENT).
After this, every ADDRESSABLE aggregate source resolves: ident
(local/module-let), deref, dot-chain, and index over array/slice/
ptr-array spines recurse through cgplaceaddr; the remaining loud
paths are rvalue sources (#40 family) and the #274 const-def arg,
both documented divergences. 8 rows added to idxdot_aggcopy_test.
pushargsrev's five aistagged gates (N_IDENT #55, N_CALL #21, N_INDEX
#12, N_DOT #22a, deref #35) treated a tagged arg as already-tagged
when its SLOT SIZE matched the param's. A same-slot subset union
((bool|void) into (i64|bool|void), both 16B) then natural-pushed the
narrower box's words carrying SOURCE tags — no re-layout, no
cg_widen_tag_remap twin — so the callee matched the wrong arm
(silent: probes exited 10/90 where cstage exits 30/27). cstage keys
widen detection on type equality (cgen.c:10000 same = (pu == au) ||
type_eq) and routes every non-same tagged source through the zeroed
scratch + tag remap; the slot-DIFFER wwstage path already mirrored
that byte-identically, so the fix computes cstage's same check once
(wsame) and replaces each slot-size test with it. This also erases
the last known cs!=ww shape divergence (the 16B-local staging vs
direct-push frame delta on prefix subsets).
8 subsetwiden_* fixtures own the class: call-result/ident/str-payload
/mid-arg remap (the wrong-arm shapes), prefix (the shape-divergence
repro), and bigslot/return-pos/struct-24-to-32 sibling guards. Corpus
pin 1740/343/22/209/1166/3480.
Pure move: log_test.ww dissolves along its banner seams into
funcs_test.ww (the six logger-arg rows — lprintlnbasic/single/empty,
lprintflnbasic/indexed/mods — plus the fatal-family subprocess TODO;
ref/hare/log/funcs.ha owns lprintln/lprintfln and the fatal/lfatal
forms) and global_test.ww (defaultwiredtoglobal, setloggerswap,
printflnglobal; ref/hare/log/global.ha owns default/global/setlogger).
Moved blocks are byte-identical; the 9 banner lines are deleted.
Imports minimized per file (log + memio; the stale fmt/io imports
drop).
Helper inventory: streq spans both halves (all six funcs rows;
setloggerswap + printflnglobal on the global side), so it is
duplicated under per-file names per the sanctioned strconv
streq/fstreq precedent — fstreq in funcs_test.ww (decl + 6 call
sites), gstreq in global_test.ww (decl + 6 call sites); bodies
byte-identical apart from the name. Line-multiset diff old-vs-concat
(heads/banners excluded, names normalized): the only residue is the
9-line streq helper counted twice.
Order-safety, proven on the composed run: dir-mode executes
declaration order per file, files byte-lexicographic (funcs_test <
global_test < silent_test). Observed order: lprintlnbasic,
lprintlnsingle, lprintlnempty, lprintflnbasic, lprintflnindexed,
lprintflnmods, defaultwiredtoglobal, setloggerswap, printflnglobal,
silentwritesnothing, silentignoresprintfln — defaultwiredtoglobal
still precedes every log.setlogger caller (setloggerswap and
printflnglobal, both later in its own file; funcs and silent rows
never call setlogger).
Consumers: Makefile LIBRARY_TESTS replaces the log_test.ww entry with
the two new entries in place; test/byteid/libbyteid_test.ww roster row

Validation: standalone ww test lib/log/funcs_test.ww (6 passed) and

Pure move: bufio_test.ww dissolves along its banner seams into
stream_test.ww (13 stream* rows) and scanner_test.ww (13 scan*/
newscanner*/emptystream/errorsource/boundarycases/multifill/
readaheadcantgrow rows), mirroring ref/hare/bufio/{stream_test+test.ha,
scanner_test+test.ha} ownership. streamscannerunread stays stream-side:
Hare's stream-level unread test lives in stream_test+test.ha:86.
Moved blocks are byte-identical; the 28 file-scope banner lines (and
their // continuation lines) are deleted, the 2 interior banners inside
boundarycases stay. Imports minimized per file (the unused `import
bytes;` drops; utf8 is scanner-only).
Helper inventory: putstr spans both halves (7 scanner rows / 8 call
sites; 8 stream rows / 8 call sites), so it is duplicated under
per-file names per the sanctioned strconv streq/fstreq precedent —
scanner_test.ww keeps `putstr`, the stream copy is `sputstr` (decl,
head comment, 8 call sites; body otherwise byte-identical). The
error-returning source (errvt/errread/errwrite/errsource) moves with
its sole consumer errorsource into scanner_test.ww; the close-recording
source (srcclosed/closevt/closesink/closewrite/closeclose/closesource)
moves with streamclosenopropagate into stream_test.ww. Line-multiset
diff old-vs-concat (heads/banners excluded, sputstr normalized): the

taggedcallslot gated on an N_IDENT callee + fnretlookup, so every
N_DOT / wwi-decl'd cross-module callee (and every fn-pointer call)
returned 0 and its tagged call-result ARG fell off the cursor-push
path into a 16B scratch spill where cstage PUSHQes AX/DX (cstage keys
the same push on args[i]->type, cgen.c tagged_arg_size). Read the
stamped result type instead — the #209/#211 predicate-to-stamp
discipline, same class as the fn-value cgident fix.
Graduates BOTH remaining DATABYTEID_DIVERGED pins
(r700_strings_byteindex frame 80->64, r839_xmod_nominal_match frame
32->16) — the ledger is EMPTY; the byteid gate ran 1389 data fixtures
at 0 pinned-divergent. Lang rows cover the same-module control,
fn-pointer, float-member, and str-member shapes (byte-identical each).
Separate latent lead banked, NOT closed here: the tagged
subset-widening call arg ((i64|bool) passed as (i64|bool|void))
byte-diverges pre-existing — cstage stages through a 16B local,
wwstage passes direct; runtime-equivalent.
The last Open-driver-work bullet. `-c -o <name>` replaces the fixed
<package>.test stem for exactly one package; the coordinator rejects a
multi-package fan-out ("cannot use -o with multiple packages", Go's
`go test -o` rule) and -o without -c is rejected at the driver
("needs -c for a package target" — a plain run executes from the temp
root, so a caller-owned name has nothing to name). Both driver stages
byte-identical wording; -S keeps its single-file-only reject.
package_test gains the contract row (naming, fixed-stem absence,
artifact runs, both rejects, both drivers); the tree-mode -o row's
pinned wording follows the contract.
Pure move: utf8_test.ww dissolves along its banner seams into sibling
rune_test.ww (runesz/utf8sz), encode_test.ww (encoderune),
decode_test.ww (decoder next/prev/validate/remaining/slice/position
plus the encode->decode round-trip), and types_test.ww (strerror),
mirroring ref/hare/encoding/utf8/{rune,encode,decode,types}.ha
ownership (types.ha:12 owns strerror). Blocks are byte-identical;
only the banner lines are deleted. The streq helper moves with its
sole consumer, strerror_cases, into types_test.ww. The impl utf8.ww
is untouched (no banners).
Consumers: Makefile LIBRARY_TESTS replaces the utf8_test.ww entry
with the four new entries at the same position; the
test/byteid/libbyteid_test.ww roster row becomes four fx rows,
NENTEXPECT 52->55 (+3).
Pure move: bytes_test.ww dissolves along its banner seams into sibling
equal_test.ww, index_test.ww (u8 + []u8 arms of index/rindex),
contains_test.ww (contains/hasprefix/hassuffix), tokenize_test.ww
(tokenize/rtokenize/peektoken/remainingtokens + splitn/rsplitn/split +
cut/rcut), and trim_test.ww, mirroring ref/hare/bytes/{equal,index,
contains,tokenize,trim}.ha ownership (Hare keeps splitn and cut in
tokenize.ha; contains.ha owns hasprefix/hassuffix). Blocks are
byte-identical; only the banner lines are deleted. Helpers stay with
their sole consumers: expect_token/expect_done/expect_tok in
tokenize_test.ww, beq in trim_test.ww.
Consumers: Makefile LIBRARY_TESTS replaces the bytes_test.ww entry
with the five new entries at the same position; the
test/byteid/libbyteid_test.ww roster row becomes five fx rows,
NENTEXPECT 48->52 (+4).
Pure move: the hasprefix/hassuffix, contains, byteindex/rbyteindex/
index/rindex, and compare sections of strings_test.ww become sibling
suffix_test.ww, contains_test.ww, index_test.ww, compare_test.ww,
mirroring ref/hare/strings/{suffix,contains,index,compare}.ha
ownership. Blocks are byte-identical; only the section banner lines
are deleted (the file names now carry them).
The remaining families (dup, concat, trim, sub, utf8, iter, tokenize,
pad, replace, cut) stay in strings_test.ww: they all consume the
file-local streq helper, and a helper cannot be shared across split
test files — a single-file test root does not pull same-package
siblings (undefined: helper), while dir-mode composes all package
test files into one unit (duplicate fn helper). Splitting them would
force either helper duplication or renames, both out of scope for a
pure move.
Consumers: Makefile LIBRARY_TESTS gains the four new entries beside
the strings_test.ww row; test/byteid/libbyteid_test.ww roster gains
four fx rows, NENTEXPECT 44->48 (+4).
hton/ntoh -> network.ww (ref/hare/endian/network.ha:5-36); be* byte
get/put -> big.ww (ref/hare/endian/big.ha:5-48); le* -> little.ww
(ref/hare/endian/little.ha:5-48). ww does not port endian.ha's host
dispatch, so no host file appears.
Pure move: every fn is byte-identical; the three section banner
lines are deleted (file names now carry them). The module-doc header
rides with network.ww — its amd64-is-LE sentence is the WHY for
hton being a swap.
Consumers: Makefile WWFIXTURE_SRC entry replaced in place. The
byteid roster is untouched: lib/endian is enrolled as an
import-probe keyed on `package endian;`, which every new file
still declares.
Mirror ref/hare/path's impl layout in the test siblings:
abs/isroot/string/local rows -> buffer_test.ww (ref/hare/path/
buffer.ha:28-77); push/parent/pop-split rows -> stack_test.ww
(ref/hare/path/stack.ha:9-180); dirname/basename rows ->
posix_test.ww (ref/hare/path/posix.ha:17-71).
Pure move: every @test block is byte-identical; only the section
banner lines are deleted (file names now carry them) and each
section's ref-cite WHY comment rides with its @test. The suite
header's Hare-vector/parallel-array WHY paragraphs ride with
stack_test.ww (push is their subject); the stale `ww run
lib/path/path_test.ww` sentence is dropped, not relocated.
Consumers: Makefile LIBRARY_TESTS entry replaced in place. The
byteid roster is untouched: lib/path is enrolled there as an
import-probe, not a fixture.
Mirror ref/hare/time's impl layout in the test siblings: constants ->
duration_test.ww (ref/hare/time/duration.ha:9-18 owns the constants);
now/sleep rows -> instant_test.ww (instant is the subject type,
ref/hare/time/instant.ha; now/sleep bodies live in
ref/hare/time/+linux/functions.ha, a platform split ww does not have);
add/diff/compare rows -> arithm_test.ww (ref/hare/time/arithm.ha).
Pure move: every @test block is byte-identical; only the section
banner lines are deleted (the file names now carry them). The stale
file header naming the retired `ww run lib/time/timetest.ww` entry
point is dropped, not relocated (rule 8: it described a WHAT that no
longer exists).
Consumers: Makefile LIBRARY_TESTS entry replaced in place;
test/byteid roster 44->46 (+2).
Pure file-boundary move: the two silent-logger rows
(silentwritesnothing, silentignoresprintfln) leave lib/log/log_test.ww
for lib/log/silent_test.ww, mirroring ref/hare/log/silent.ha's
ownership (ref/hare/log has no test files of its own; the file name
follows the impl layout as directed). Only the two banner lines are
deleted; both moved blocks are byte-identical. silent_test.ww imports
log + memio only (neither row uses streq/fmt/io).
The specced funcs_test/global_test halves stay merged in log_test.ww:
the streq helper is consumed by six lprint* rows AND the
setloggerswap/printflnglobal global rows, and same-package test files
compile as one unit in dir mode (duplicate fn rejected), so that
boundary cannot be a pure move; reported upstream rather than
relocating the majority of rows.
Ordering: defaultwiredtoglobal must precede any log.setlogger caller.
All setlogger callers (setloggerswap, printflnglobal) remain after it
in log_test.ww; the silent rows never touch setlogger, and dir-mode
concat order (pkgsort: log_test.ww < silent_test.ww) keeps
defaultwiredtoglobal first overall.
Consumers: Makefile LIBRARY_TESTS gains lib/log/silent_test.ww beside
the log_test.ww entry; test/byteid/libbyteid_test.ww roster gains
fx("lib/log/silent_test.ww") after the log_test row, roster 44->45
(+1, NENTEXPECT bumped).

Pure file-boundary move of lib/io/stream.ww's single 'empty stream'
banner section (_empty_read, _empty_write, _empty_vt, empty) into
lib/io/empty.ww, mirroring ref/hare/io/empty.ha. No code, name,
signature, or behavior change. Comment-only adjustments: the banner
line is deleted (the file name carries it); the moved block's
'Lives in stream.ww' self-reference now says empty.ww; stream.ww's
head drops its empty bullet (content duplicated by empty.ww's own
comments); io.ww's ownership map gains the empty.ww line; types.ww's
'three files' count becomes four. empty.ww needs no imports (package
io types only).
Makefile: lib/io/empty.ww added beside every lib/io/stream.ww
occurrence (WWFIXTURE_SRC line 75; w6c_ww/wwdump_ww bootstrap prereq
lists at lines 184/204). lib/io has no _test.ww, so no LIBRARY_TESTS
or byteid-roster change; byteid coverage rides the bootstrap gates.
Validation: out/bin/w6c lib/io/io.ww (standalone contract) exit 0;
importer tests green: bufio 26, memio 11, log 11, getopt 12 (calls
io.empty), fmt 49.
Pure file-boundary move of lib/bufio/bufio.ww along its three banner
seams: buffered stream + vtable callbacks -> stream.ww (per
ref/hare/bufio/stream.ha), scanner + BUFSZ + overflow -> scanner.ww
(per ref/hare/bufio/scanner.ha). Head defs split by ownership:
flushdefault + rtabort (unread's assert) stay with stream, BUFSZ
(scanner.ha:11) + overflow with scanner. The module head comment
stays with stream.ww. No code, name, signature, or behavior change;
the three banner lines are deleted (file names carry them) and three
comment self-citations re-point (bufio.ww:87-89 -> stream.ww:73-75,
bufio.ww:46-50 -> stream.ww:46-50, bufio.ww:77 -> scanner.ww:15), plus
the lib/regex/regex.ww:1117 citation of lib/bufio/bufio.ww now names
scanner.ww. import bufio resolves by directory (cmd/ww locate_import
dir pass), so no consumer path lists change; bufio_test.ww is
untouched (its split is blocked by the shared putstr helper vs the
composed-mode duplicate-symbol reject; reported upstream).
Validation: out/bin/ww test -I lib/ww lib/bufio/bufio_test.ww (26
passed) and out/bin/ww test lib/bufio (ok, external) both green;
lib/regex/regex_test.ww (bufio importer) 33 passed.
`case T1 | T2 =>` (binding-less; cstage parse.c:635-650 chains extra
types through cs->list, bindings stay single-type by design). Three
wwstage layers, no AST change (node.list already exists):
- parser (expr.ww): pipe loop after the non-let arm's first
parsetype;
- checker (check.ww): resolvewalk N_MCASE now walks n.list so each
alt gets its type_ stamp (exhaustiveness/casecovers were already
alt-aware, built ahead of the parser);
- cgen (cgenexpr.ww): the single-pattern want-computation moves
VERBATIM into matcharmwant; a cs.list arm emits CMPQ/JE per alt
funneling into one match_body label, mirroring cgen.c:11118-11141
incl. label mint order and the tag<0 clamp. Nullable arms keep
ignoring alts (both stages).
Graduates the held e2e row (pin 1732/1158/3464); byte-identical on
the repro and the single-pattern control.
cstage parse.c:1027 accepts `for ()` — N_FOR with a nil cond, no
for-else arm, no test emitted (an unconditional loop; a deliberate
Go-flavored ww divergence from Hare, original to the toolchain
import). The wwstage parser had no RPAREN early-out and rejected it.
Selfhost checker and cgen already nil-guard n.cond, so the parser arm
is the whole gap. Graduates the held e2e row (pin 1731/1157/3462).
Adjacent asymmetries left filed, not fixed here (rule 11): the brace
form `for { }`, the empty middle clause of the 3-clause form, and
the REVERSE case (wwstage accepts 2-clause `for (cond; post)` which
cstage rejects).
wwstage dotchainresolve gated its *T roots on an N_TPTR-over-N_TNAME
tnode; an inferred `let p = alloc(S{...})!` rides the checker-
SYNTHESIZED N_TPTR whose pointee is the struct BODY node (the #24
TNAME-normalize covers only the direct struct-lit binding), so the
root gate failed and chained p.field.pseudo reads fell to the
unfused deref arms — shape-only divergence vs cstage's type-keyed
fold (both stages runtime-correct; the historical field(SB) leak the
pin described was already fixed). Widen the local and global root
gates to accept the N_TSTRUCT pointee; correctness stays enforced by
the stamped-tinfo peel below (TY_PTR -> pointee TY_STRUCT).
Graduates alias_g73_heapfill out of DATABYTEID_DIVERGED (2 pins
remain, both the tagged-spill family); adds compile fixtures pinning
the newly-converged siblings (nested read+store, slice .cap,
inferred-global root; pin 1730/22/3460) and a runtime lang row that
mutates then re-points the heap base — a read bypassing the pointer
returns the wrong len.
The last bug-pinned C carrier. Its header documents both #55 halves;
with the cgen side fixed the STRONGER assertion set it deferred is
expressible: barevalue builds the 794 two-file program FLAT
(file-keyed import — a dir-keyed aa/ compiles aa as its own sep unit
where main.v is invisible and the collision cannot express), runs
exit 7 on BOTH drivers, and asserts the flat __root.s cs==ww
byte-identical (rule 10). defshadow pins the def-vs-fn arm-order
corner (foreign scalar def under a curmod fn: bare read 42, not
141), modqualfnval the qualified fn-value positive twin.
Carrier fleet 16 -> 15: 5 units / 6 bootstrap / 3 platform /
738_module_decl. Zero bug-pins remain.
wwstage cgen re-derived fn-ness by NAME: cgident's fn arm gated on
fnretlookup, whose cross-module leaf fallback matches a foreign
same-leaf fn — inside aa.getv the bare `v` (aa's i32 global, stamped
by the #55 prefer fix) took the fn-address arm for main's `fn v` and
emitted LEAQ aa.v(SB) with no deref; the ww_ww-built 794 program
exited 0 instead of 7. cstage reads the checker-stamped type
(cgen.c:4315). Convert the three value-position sites to the stamp
(same predicate-to-stamp conversion as the #14 F7-c7 `&fn` arm):
cgident (now TY_FN -> def -> let, cstage's order — the def-first
order also mis-read a foreign scalar def shadowed by a curmod fn),
the cgdot module-qualified value arm, and the `&ident` #180 arm.
Call-position fnretlookup consumers are unchanged.
The 794 two-file program is now cs==ww byte-identical and both
drivers run exit 7; the carrier retires in the follow-up.
The dot-chain SOURCE-address walkers (cg_dotchain_addr /
dotchainaddr) deliberately have no index hop — their AX-clean spill
contract serves the chained dotbase arm — so an aggregate copy from
elem[k].field (N_DOT over N_INDEX) fell out of the walk. Every
aggarg_srcaddr consumer loud-stopped (arg push #271, aggregate
return #272, field assign, structlit fill, ident reassign) EXCEPT
the indexed element-store arm, which left the walker's result
UNCHECKED and copied through a stale SI — a silent both-stage
miscompile (out[j] = hs[k].result read garbage). Task #6.
Both stages, two twin edits each: the aggarg_srcaddr N_DOT arm falls
back to cgplaceaddr (the C4/#40 place resolver, emission-free-on-
failure so the fallback starts clean), and the indexed store site
checks the walker before the same fallback.
Still loud (filed follow-ups): auto-deref pointer-to-array indexed
bases (hs: *[4]T; hs[k].field — cgplaceaddr's index arm takes no
deref hop; the explicit (*hs)[k].field form works), and the bare
N_INDEX slice-element aggregate source.
The #173 remap loop in cgtryprop gated on the tparam's explicit `!`
flag only; a LEGACY union (no marks anywhere) classifies error
variants POSITIONALLY (index 0 is success, cstage cg_variant_is_error
cgen.c:905) — so wwstage emitted no remap and propagated the callee's
raw tag into a differently-ordered caller union, a silent wrong arm
(cstage exit 7, wwstage 9 on the banked r700 row). Add the
variantiserror twin and gate the loop on it; refresh the drifted
cstage cite.
Graduates the held e2e row into the corpus (pin 1727/1156/3454) and
adds legacy-mode rows to test/lang/tryprop_tag_remap_test.ww:
reversed order both directions, slot-0 remap, str payload integrity,
a two-hop chain whose pre-fix runtime pass was double-miss tag
cancellation (the lang byteid leg pins the emitted remap blocks),
and a same-order zero-emission control.
The three modules pass bare (loud SKIPs on absent env); their arranged
legs stay owned by test/libenv. Closes the deliberate scope cut from
the os wave.
test/libenv/libenv_test.ww owns the env-arranged legs of the lib/os
getenv and lib/dirs XDG suites (rows asserted ok, not SKIP, plus the
created-chain layout), the dirs too-long abort on both stages, and the
make-owned runner for the self-arranged stat suite. Wired beside the
sep observers under test-compiler.
The three must-abort runs (u32n/u64n zero, decodedsize unaligned) move
into the owning lib suites as test.expectabort rows; the five
normal-return controls already live in the r989_libprecond_* fixtures.
wwstage parity rides the lib-wide cs==ww byte identity gate.
Each row builds regfile/symlink/subdir under temp.dir (Hare's os-test
idiom) and asserts exact cleanup, so the suite passes bare and the
carrier's env+tree arrangement job disappears. Every carrier assertion
maps to an in-test row.
Strengthens the pre-symmetry-era cstage-only stdout scrape to both
frontends with gated exits and the rule-10 cs==ww byte-id; the libc
binding smoke likewise runs both stages.
One commit for both carriers: the asserttyped manifest and the -c/-r
parse-error gate are the same wwstage-only wwdump_ww subprocess
surface. The 901_*.ww raw gap companions stay in test/wcc, fed via
testenv.repo().
One commit for both carriers: flag-misuse parity and the
missing-package fatal are the same driver-CLI subprocess surface. The
-V oracle parses WW_VERSION out of cmd/wcc/ww.h at run time; the
missingpkg ww_ww twin stays owned by bootstrap carrier 993_ww_ww.c.
Ports 708_param_shadow_mod, 712_redecl and 961_opaque_guards into
test/tool/rejects_test.ww on testenv, one commit because the three
carriers share the single asymmetric-polarity claim (cstage rejects,
wwstage accepts) that a both-stage //ww:error fixture cannot carry.
The neg_selfimp leg drops: test/wcc/data/r948_selfimport/case.ww owns
the identical both-frontend claim.
