test: port the assert/abort run-stderr net to ww; retire 957_assert_builtin_run
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.

/*

* 957_assert_builtin_run — stderr + byte-id net for #58: the
|
|
||||||
* `assert(cond[, msg])` / `abort([msg])` builtins (the harec
|
|
||||||
* EXPR_ASSERT family) in BOTH stages.
|
|
||||||
*
|
|
||||||
* Root: wwstage had NO builtin intercept for assert/abort — the checker
|
|
||||||
* left the call untyped (asserttyped gate 4 deliberately skipped it)
|
|
||||||
* and cgcall fell through to the regular call path, emitting
|
|
||||||
* `CALL assert(SB)` for a symbol that exists nowhere → link-fail.
|
|
||||||
* cstage lowers both inline via rt_abort (checker tags the callee
|
|
||||||
* ty_err at cmd/wcc/check.c:1536-1572, cgen keys on the tag at
|
|
||||||
* cmd/w6c/cgen.c:6618-6663). The fix mirrors that tag-then-lower pair
|
|
||||||
* into check.ww exprtype N_CALL + cgenexpr.ww cgcall.
|
|
||||||
*
|
|
||||||
* Shared runtime and reject contracts live in r957_* fixtures. This carrier
|
|
||||||
* retains runtime stderr for aborting rows and w6c vs w6c_ww `.s` identity.
|
|
||||||
* The latter fails if the stages diverge. On
|
|
||||||
* pre-fix master every assert/abort row diverges (wwstage emits
|
|
||||||
* the bogus CALL).
|
|
||||||
*
|
|
||||||
* Shadow rows pin the gate's other half: a user fn named assert/abort
|
|
||||||
* (same-module or cross-module, the #45 shape) suppresses the builtin
|
|
||||||
* and routes the regular call path in BOTH stages. The cross-module
|
|
||||||
* row pins the CURRENT flat-scope semantics — if the #45 root (filed
|
|
||||||
* as task #14: cross-module bare resolution of a foreign decl) is
|
|
||||||
* later ruled a reject, its fixture should change polarity with it.
|
|
||||||
*
|
|
||||||
* The migrated reject fixtures retain the checker diagnostics and the
|
|
||||||
* alias-cond rule-10 down-alignment.
