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.

// Register a brand-new Obj-C class from sx and prove a sx-defined method
|
|
// actually runs when dispatched through `objc_msgSend`.
|
|
//
|
|
// The flow:
|
|
// 1. `objc_allocateClassPair(NSObject, "SxThing", 0)` returns an unregistered Class.
|
|
// 2. `class_addMethod(cls, sel_hello, IMP, "v@:")` attaches our sx function as
|
|
// the `hello` method (type encoding "v@:" = void method(id self, SEL _cmd)).
|
|
// 3. `objc_registerClassPair(cls)` finalizes it.
|
|
// 4. `class_createInstance(cls, 0)` returns an `id` for a fresh instance.
|
|
// 5. typed-cast `objc_msgSend` for `void (id, SEL)` and dispatch `hello`.
|
|
// If the IMP ran, the global `g_marker` is non-zero and we return it as exit.
