Surface rename of the signed integer family: s1..s64 become i1..i64
(u1..u64, usize, isize unchanged). 'string' keeps the s-prefix arm in
name classification; width parsing moves to the i-prefix arm next to
isize.
Internal TypeId tags follow the surface (.s8/.s16/.s32/.s64 ->
.i8/.i16/.i32/.i64), as do mono-key mangle fragments (ptr_i64,
tu_i64_bool) and all display/diagnostic formatting (i{d}).
Migrated in the same sweep: stdlib + examples + issue repros + FFI C
companions (shared symbol names like ffi_id_i64), expected
stdout/stderr/ir snapshots, specs.md, readme.md, CLAUDE.md/AGENTS.md,
implementation_plan.md, docs/, issue writeups. Vendored stb_image and
historical flow state left untouched.
zig build test: 426/426; examples suite: 595/595.

// M1.2 A.1 follow-up — pass-by-value struct args/returns in
|
|
// sx-defined `#objc_class` methods.
|
|
//
|
|
// Wires the new `{Name=field0field1...}` arm of
|
|
// `appendObjcEncoding` into `class_addMethod` registration. Without
|
|
// it, methods that take or return a value-type struct (CGPoint,
|
|
// CGSize, NSRange shapes) used to fail signature-encoding
|
|
// derivation with a "type kind not yet supported" diagnostic.
|
|
//
|
|
// Each sx-defined method registered with the Obj-C runtime needs an
|
|
// encoding string built from its IR signature. For
|
|
// `goto :: (self: *Self, p: Point)` that string is `v@:{Point=dd}`
|
|
// — return void, receiver `@`, selector `:`, then the struct
|
|
// argument `{Point=dd}`.
|
|
//
|
|
// We don't observe the encoding string directly here (it ends up in
|
|
// a private OBJC_METH_VAR_TYPE_ cstring in the linked binary) — but
|
|
// the compiler bails LOUDLY on unsupported types per the project's
|
|
// REJECTED PATTERNS rule, so a successful build is the encoding
|
|
// going through cleanly.
