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.

// Generic `Into(Block)` impl with a `string`-typed arg in the
|
|
// closure signature. The block trampoline declares the param with
|
|
// callconv(.c); without the abi-collapse fix, sx `string` got
|
|
// silently collapsed to `ptr` (the libc `char *` heuristic) and
|
|
// the caller's 16-byte `{ptr, len}` value mismatched the
|
|
// trampoline's 8-byte `ptr` slot. Result: segfault inside the
|
|
// trampoline's first read.
|
|
//
|
|
// The fix lives in `abiCoerceParamTypeEx`: the `string`/`slice` →
|
|
// `ptr` collapse only applies to `is_extern` foreign decls (libc
|
|
// interop). sx-internal `callconv(.c)` keeps the full slice
|
|
// shape, which lands as `[2 x i64]` at the LLVM signature site
|
|
// and matches the caller's two-register pass on AArch64.
