- objc.sx, objc_block.sx (from std/) + sdl3/opengl/raylib/stb/stb_truetype/ wasm vendor bindings (from modules/ root) -> modules/ffi/ - std/uikit.sx deleted: platform/uikit.sx already declares UIApplicationMain and imports objc; '#framework "UIKit"' cannot live in a file imported on macOS targets (unconditional link directive, UIKit is iOS-only), so the three iOS-only examples carry the 3-line glue inline. 1607/1608/1616 also un-rotted (dead ns_string -> 'xx "..."' Into conversions, callconv(.c) msgSend fn-ptrs) — all three build for ios-sim/ios again. - math/math.sx -> math/scalar.sx; one spelling '#import "modules/math"' everywhere (4 pinned IR snapshots regenerated: dir import adds Vec2/Mat4 to the type tables). - compiler.sx -> build.sx (imports, CLAUDE.md bundling table, specs.md). - testpkg/ + test_c.sx -> tests/fixtures/ (resolve CWD-relative from repo root, same as vendors/). - library-internal imports use full modules/... paths (std.sx tail, platform/bundle.sx, fixtures).

// ffi-objc-arc-00 — M4.0 end-to-end allocator threading regression.
|
|
//
|
|
// Verifies that the per-instance allocator design from M1.2 A.5 + M4.0
|
|
// is actually wired:
|
|
// 1. `push Context.{ allocator = xx tracker } { SxFoo.alloc(); }` →
|
|
// the state struct is allocated via tracker (not libc).
|
|
// 2. The state struct's first field is `__sx_allocator` (captures the
|
|
// tracker so -dealloc can free through it).
|
|
// 3. `f.release()` drives refcount → 0 → -dealloc fires → reads the
|
|
// captured allocator → calls tracker.dealloc(state).
|
|
// 4. The alloc/dealloc deltas around the call pair balance to (+1, +1)
|
|
// — exactly one sx-defined-class state struct round-trips.
|
|
//
|
|
// Pre-M4.0 the +alloc IMP used libc `malloc` and -dealloc used libc
|
|
// `free`, both bypassing context.allocator — tracker would have
|
|
// observed (+0, +0) deltas, missing the leak silently.
|
|
//
|
|
// Important: capture tracker counters BEFORE and AFTER the
|
|
// alloc/release with NOTHING else allocating in between. `print`
|
|
// allocates strings (NSString-backed), which would also route through
|
|
// tracker and pollute the deltas.
