- 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).

// Phase 1 step 1.4 (PLAN-FFI.md): multiple `#objc_call` sites
|
|
// with the same selector. Today (after 1.3) each site emits its
|
|
// own `call @sel_registerName(<"init">)`; the actual SEL handle
|
|
// is recomputed per call.
|
|
//
|
|
// 1.5 lands selector interning: one static `SEL` global per
|
|
// unique selector string (named `OBJC_SELECTOR_REFERENCES_init`,
|
|
// matching clang's convention) populated once via the runtime
|
|
// at module init. Per call site becomes a single load.
|
|
//
|
|
// Runtime behavior is unchanged before vs. after 1.5; the
|
|
// improvement is visible in `sx ir` only. The IR snapshot at
|
|
// `tests/expected/ffi-objc-call-03-selector-sharing.ir` locks
|
|
// in today's shape (4 `call ptr @sel_registerName` instructions,
|
|
// one per call site). After 1.5 lands selector interning, the
|
|
// snapshot updates to ≤2 (one per unique selector string) plus
|
|
// a static `@OBJC_SELECTOR_REFERENCES_<sel>` global and loads at
|
|
// the call sites.
