- 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).

// M1.2 A.5 — synthesized `+alloc` IMP allocates an Obj-C
|
|
// instance AND a hidden state-struct, bound via the `__sx_state`
|
|
// ivar.
|
|
//
|
|
// Round-trip below:
|
|
// 1. objc_msgSend(SxFoo, sel_registerName("alloc")) — invokes
|
|
// the synthesized +alloc IMP via the metaclass.
|
|
// 2. Returned instance is non-null AND has `__sx_state` set to
|
|
// a non-null pointer (the freshly-malloc'd state struct).
|
|
// 3. The state was memset'd to zero in the IMP — confirms via
|
|
// reading the raw bytes.
|
|
//
|
|
// Once A.6 lands (-dealloc) and A.7 opens the dispatch gate,
|
|
// sx-side `SxFoo.alloc().init()` and method calls will exercise
|
|
// the full lifecycle.
