Rename all example tests/companions to the XXXX-category-test-name scheme (per-category 100-blocks: basic 0010, types 0100, ... errors 1000, diagnostics 1100, ffi 1200, ffi-objc 1300, ffi-jni 1400, vectors 1500, platform 1600). Companions and dir/C fixtures move in lockstep with their parent test; #import/#source/#include paths rewritten to match. Expected output now lives in examples/expected/ (a sibling dir of the tests) split into three streams per the new convention: <name>.exit / <name>.stdout / <name>.stderr (+ optional <name>.ir) run_examples.sh rewritten: scans examples/ and issues/ for an expected/<name>.exit marker, captures stdout and stderr separately (no more 2>&1), compares each stream + exit + optional IR snapshot. Behavior validated unchanged: every renamed test reproduces its prior merged output + exit (diffs limited to file paths/basenames embedded in diagnostics + traces, which correctly reflect the new names). Suite: 292 passed, 0 failed. 50-smoke.sx split + issue relocation + docs follow in subsequent commits.

// Phase 1 step 1.8 (PLAN-FFI.md): >16 B non-HFA struct returns
|
|
// through `#objc_call`. AAPCS64 routes these through the indirect-
|
|
// return convention: caller allocates the result slot, passes its
|
|
// pointer in x8 with the `sret(<T>)` attribute, callee writes
|
|
// through it and returns void.
|
|
//
|
|
// Register a runtime-built Obj-C class with a method that returns
|
|
// a fixed `Triple`. The IMP is a plain sx fn (callconv .c) — its
|
|
// sret-shaped lowering already works (Phase 0.3 fix for plain
|
|
// `#foreign` returns). The `#objc_call` dispatch side now produces
|
|
// the matching call shape: `call void @objc_msgSend(ptr sret %slot,
|
|
// ...)` + load. The two halves must agree on the ABI for the
|
|
// round-trip to return the right bytes.
