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.

// Nested comptime call + return — a comptime fn (`$x: i32`) whose
|
|
// body contains BOTH a nested comptime call (`print`) AND a
|
|
// `return X;` statement must lower cleanly. The wrapper fn built
|
|
// by `createComptimeFunction` saves/restores `inline_return_target`
|
|
// so it doesn't inherit a slot belonging to the OUTER caller's
|
|
// basic block. Pre-fix: interp executed the wrapper with a
|
|
// stale-frame inline-return slot and tripped a null-pointer store
|
|
// at `storeAtRawPtr`.
|
|
//
|
|
// Repro: comptime fn (`$x: i32`) whose body has BOTH a nested
|
|
// comptime call (`print`) AND a `return X;` statement. Pre-fix:
|
|
// interp panics. Post-fix: prints "inside" then "n=42".
|
|
//
|
|
// The pack-fn variant of the same bug (filed in the original
|
|
// issue as face 2) was fixed earlier when step-2b moved pack-fn
|
|
// calls off the inline path into the mono path. Plain comptime
|
|
// fns stay on the inline path; their fix is the
|
|
// `createComptimeFunction` state save/restore.
