- 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).

// Obj-C runtime FFI smoke test: round-trip a string through NSString.
|
|
//
|
|
// Demonstrates the typed-fn-pointer cast idiom for `objc_msgSend`. Each
|
|
// shape we invoke gets its own variable typed with the exact ABI:
|
|
//
|
|
// msg_3 : (*void, *void, [*]u8) -> *void = xx objc_msgSend;
|
|
// msg_2 : (*void, *void) -> [*]u8 = xx objc_msgSend;
|
|
//
|
|
// On ARM64 Apple, objc_msgSend doesn't take a varargs path — invoking it
|
|
// through a typed fn-pointer is the only correct way to land args in the
|
|
// right registers.
