- 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.4b.iii — instance-method dispatch through the Obj-C
|
|
// runtime. Each instance method now gets a C-ABI IMP trampoline
|
|
// registered via 'class_addMethod' at class-pair init time. The
|
|
// runtime can dispatch 'objc_msgSend(obj, sel)' to the
|
|
// trampoline, which reads the '__sx_state' ivar to find the
|
|
// state struct and forwards to the sx body.
|
|
//
|
|
// End-to-end (verifies registration only — sx-side
|
|
// 'obj.bump()' calls still bail at the M1.2 A.7 dispatch gate
|
|
// until +alloc/-dealloc (A.5/A.6) land too):
|
|
// 1. class_getMethodImplementation(SxFoo, sel_registerName("bump"))
|
|
// returns a non-null IMP — proves the trampoline is wired.
