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.

// FFI plan step 5.2 — generic `Into(Block) for Closure(..$args) ->
|
|
// $R` impl. One impl in stdlib covers every closure shape; the
|
|
// compiler monomorphises the impl body per call shape and emits a
|
|
// dedicated `__invoke` `callconv(.c)` trampoline + Block literal
|
|
// (via `#insert build_block_convert($args, $R);`).
|
|
//
|
|
// This test exercises a closure shape (`Closure(s64, s64) -> void`)
|
|
// that has NO hand-rolled `Into(Block)` impl in
|
|
// `library/modules/std/objc_block.sx`. Before step 5.2 lands,
|
|
// `xx cl : Block` errors out with the "no Into(Block) for
|
|
// cl_s64_s64__void" focused diagnostic. After the generic impl
|
|
// lands, the same call resolves through the pack-shaped impl and
|
|
// the per-shape trampoline ferries control back to the sx closure.
|
|
//
|
|
// The block is invoked directly through `b.invoke` (a typed
|
|
// `callconv(.c)` fn-pointer) — the same shape the Apple Block
|
|
// runtime calls when a UIKit/Foundation API hands the block back
|
|
// to its registered invoke.
