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.

// Pack-fn (or any comptime-param fn) with a block body containing
|
|
// an explicit `return X;` lowers to clean IR — the inline-return
|
|
// path stores into a dedicated result slot and branches to the
|
|
// shared `ret_done` block instead of emitting a `ret` inside the
|
|
// caller's basic block. Without that, LLVM's verifier rejected the
|
|
// IR with "Terminator found in the middle of a basic block".
|
|
//
|
|
// Surfaced by the variadic heterogeneous type packs feature (step
|
|
// 1 made `..$args` parseable, so the simplest pack-fn smoke test
|
|
// exercised the bug). The root cause is broader than packs: ANY
|
|
// comptime fn with `is_comptime` params, a non-void return, and a
|
|
// block body with `return X;` had the same crash. `format`/`print`
|
|
// use arrow form (`=> expr`) or `#insert`-only bodies, so the bug
|
|
// was invisible until pack-fn bodies surfaced it.
|
|
//
|
|
// Once fixed, calling foo() reaches the body's `return 42;`, the
|
|
// inliner stores 42 into a result slot, the caller loads it as the
|
|
// inline value, and main prints "42".
