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.
The unowned remainder is the four run-stderr assertions — msg content
for fail_msg/abort_msg, MANDATORY EMPTINESS for fail_nomsg/abort_bare
(rt_abort(NULL,0) writes nothing) — which the fixture protocol cannot
see (run exit only). The rows build the r957_* fixture sources in
place via the cstage driver; byte-id extends the lowering to wwstage
(the carrier's own argument). Owned legs cited, not duplicated: all
eight exit rows by the r957_assert_*/r957_abort_* fixtures, the
checker rejects by r957_assert_reject_*, byte-id by the
test-data-byteid blanket.
Only the ast_proof leg was unowned: wwdump -a / wwdump_ww -a dump
byte-id plus the ordered dot-over-structlit-over-tname node shape for
a trailing op on a qualified struct literal (inexpressible as a
runtime scenario while the #77 literal-temporary cgen gap holds; the
multilevel row pins the source-order a.b.C tname flatten). The three
build/run scenarios are owned by the r84_qualstruct_* fixtures plus
the test-data-byteid blanket — their vestigial want_exit fields were
already dead in the carrier.
954_tuprecv_run, 956_tuprecv_f64_run and 956_modqualdestr_run shared
one retained dimension: w6c_ww compiles the destructure shape cleanly
AND emits no asserttyped stderr diagnostic (#121 A-narrow / #6a-A
stamp nets) — a channel neither test/lang nor the fixture protocol
has. All 11 rows fold into one observer with the drew-C4 non-vacuity
self-check on the shared predicate. Owned legs cited, not duplicated:
value rows + byte-id ride test/lang/tuprecv_test.ww,
test/lang/tuprecv_f64_test.ww and the test-lang-byteid blanket; the
modqual values + byte-id ride the r956_modqual_* fixtures and
test-data-byteid — those four rows compile the fixture files in place
so probe and fixture cannot drift. Bundled: one file, one concern
(the wwstage stamp-absence dimension).
826_alias_tuple_coerce, 944_alias_accept_run and
944_variant_chain_b95_run all reduced to the same irreducible shape: a
LIVE per-stage asymmetry (probed at HEAD) no symmetric fixture or
@test can host. Ported under the DIVERGE discipline — both sides
asserted loud (826 neg_0: cstage "not assignable to declared pair"
vs wwstage over-accept; #96: cstage runs vs w6c_ww "unsupported
address-of shape"; #277: cstage runs vs ww_ww "deferred #277"), so
a fix on either side fails the row and demands graduation. Owned legs
cited, not duplicated: r826_alias_tuple_* byte rows ride
test-data-byteid, 826's neg_1 went symmetric at HEAD and moves to a
//ww:error fixture per the audit split, the 944 value/reject corpora
live in test/lang/{alias_accept,variant_chain_b95}_test.ww and the
alias_*/vchain_* fixtures. Bundled: one file, one concern (held
divergence pins).
Both carriers were already slim: the r76_def_widen_* byte-id legs are
owned by the test-data-byteid blanket, 783's positive byte rows by the
r78_amp_fn_assign_* fixtures plus that same blanket, and its symmetric
non-tagged rejects by the corpus //ww:error fixtures. The unowned
remainder is three cstage-only loud-rejects (the 760 narrowing def-ref
and 783's two tagged-slot rows); the wwstage over-accepts (no def-init
assignability check; #214 void-variant leniency) are documented at the
site per the residual audit, never asserted as desired — the rows
graduate to //ww:error fixtures when the wwstage side tightens.
Bundled: one file, one concern (cstage-reject pins awaiting wwstage
graduation).
wwiroundtrip pins the @packed re-emit through a real -I tree on both
driver stages (importer-side layout exit 91), strengthened with the
`struct @packed {` needle in the retained sepwork pk2.wwi (a
single-file two-package form emits no .wwi, so the tree is
irreducible). identityreject pins the stage asymmetry as a DIVERGE
row: cstage rejects with "not assignable" (packed is type identity,
harec types.c:621), wwstage builds+runs through the documented
#224/#10 nominal-lossy leniency; a wwstage tighten fails the row and
demands graduation to a //ww:error fixture. The 15 layout/runtime
value rows are fixture-shaped and move to the declarative corpus per
the residual audit port split.
test/misc hosts the residual mixed-shape observers (divergence pins,
stamp/stderr probes, .wwi trees) on testenv, wired into test-compiler
beside the sep/xmod/asm families; its rule declares both full
per-stage toolchains plus the wwdump twins for the coming files.
The 689 port keeps the both-driver run-exit-6 backstop and the
per-stage absolute DATAW row count (linker dedup and byte-id sweeps
are both blind to a symmetric double-emit).
The 18 active rows keep compile + cs==ws byte-id and the tab-anchored
ADDQ $N,SP cleanup markers with both polarities (mem-class rows must
contain their slot's cleanup; the exactly-48B boundary row must not).
The per-row driver build+run legs (incl. the uninit-global zero-box
exit 91) move to the r929 run fixture corpus per the residual audit
port split; the four buildfail rows were already dead here, owned by
the r929_memarg_reject_* fixtures.
The 13 active rows keep compile + cs==ws byte-id and the hidden-RDI
"(BP), DI" presence/absence polarity (present iff sret-class; the two
exactly-32B boundary rows must stay register). The per-row driver
build+run legs move to the r926 run fixture corpus per the residual
audit port split; the seven buildfail rows were already dead here,
owned by the r926_sret_reject_* fixtures.
The five symmetric rows compile their r764_amp_fn_ident_* fixture
sources in place (runtime owned by those fixtures; pre-fix junk-store
still exits 0, so the LEAQ window is the discriminator) and keep the
cs==ws byte-id leg. The cross-module row stays cstage-only pending
#184; its wwstage/byte-id legs graduate with that task.
asmgate_test.ww absorbs 530_w6a_parsenum and 989_datargate_run: the
strtoll-semantics identity rows plus the bare-minus reject against
both assemblers with cross-stage .o byte-identity, and the undefined
DATAR-slot loud reject (no .o written) with the defined-slot
byte-identical ok path. The w6a_ww skip gates drop: the Make target
declares both assemblers.
archive_test.ww absorbs 610_arch and 632_w6l_manyflags: archive
member selectivity through a load-bearing undefined @symbol extern
(link exit 0, run exit 7), and the -L capacity table {1,64,65,100,
128} against both w6l and w6l_ww with an ET_EXEC check per leg. ar is
/usr/bin/ar via runcommand; the junk -L flags are real argv entries
instead of a 16KB shell string.
link_test.ww absorbs 600_w6l and 620_data_link: ET_EXEC on the
trivial pipeline, writable-global read/write runs, the exact
two-PT_LOAD R+X/R+W split, the single-PT_LOAD no-DATAW invariant 992
depends on, and the BSS filesz trim (filesz 1 < memsz 32, loader
zero-fill). Strengthened: the ldd staticness proxy is replaced by a
direct no-PT_INTERP phdr scan.
elfobj_test.ww (test/object, on testenv) absorbs 500_w6a, 510_dataw,
and 520_datar: ELF64 header magic/class over the 4 inline programs,
DATAW section/symbol layout plus the 6-section no-DATAW legacy
invariant 991 depends on, and the DATAR .rela.data reloc through
link and run. Strengthened: the reloc symbol is resolved to
'greeting' (declared but never implemented in the C carrier).
The test/object observers parse assembler/linker artifacts; the
readers reinterpret readfile's byte str and route through endian's
canonical legetu* instead of re-deriving the bit math.
728 -> test/asm/matchdispatch_test.ww. The distinct-CMPQ-tag
collection window over TEXT b.next preserved on both stages.
Strengthened: per-row byte-id legs added -- the C header claimed a
cmp -s its code never ran; all three rows verify green.
719/724/744/746 -> test/asm/dataemit_test.ww. Exact DATAW payload
needles, the produce-window zero-init and MOVQ-load count floors,
and the strdef inline-pair want/anti windows preserved with their
per-row byte-id legs.
720/723/727/743 -> test/asm/callarg_test.ww. Ordered PUSHQ windows,
tag-synth + stack-overflow-cleanup needles and the variadic
eightbyte store-count floors preserved. Strengthened: 720's
4-variant row gains the byte-id leg the C skipped behind the
then-open #22 zero-init gate — #22 landed (724 pins the fix), and
the leg verifies green on both stages.
718/721/730 -> test/asm/sret_test.ww. Frame-size and max--K(BP)
stomp sentinels, line-adjacency sret triangle (hidden-RDI, return-
the-pointer, no-AX-capture, forwarding reload) and narrow-trailing-
field windows preserved, including 718's #15 byte-id gate on the
three-return row. 718's whole-suite ww_ww-executable gate dropped
with the other skip gates (the Make target declares the tools).
726/731/732/733/734/735/745/747 -> test/asm/modshadow_test.ww, one
@test per carrier, every want/anti window, occurrence floor and
byte-id leg preserved. New ASM_WW_TESTS block runs the test/asm
observers under test-compiler beside the residual carriers.
test/xmod/typecheck_test.ww replaces 989_callarg_typecheck.c and
989_tagged_subset_reject.c. Preserved: both -T __wwtests reservation
faces (both stages, diagnostic required), the shape-mismatch collision
(both stages), the cstage-only same-shape #37 pin, and both tagged
leaf-bridge xmod rows. Not ported, owned elsewhere per the audit: the
carriers' twelve ordinary call-arg rows (r989_callarg_* fixtures) and
the three w6c-vs-w6c_ww byte-id rows (test-data-byteid over
r989_tagsubset_{flatten_subset,slice_subset,nested_wrap}).
test/xmod/label_test.ww replaces 706_fnlabel_mangle.c and
750_mklabel_modscoped.c with every assertion preserved (fnlabelmangle
fixture run-112 both stages; three mklabel rows with run exits and
module-qualified label needles). Strengthened: fnlabel adds the
cs==ww sepwork .s byte-id the carrier never asserted.
