Unified sx<->compiler binding that subsumes the metatype declare/define
primitives AND the #compiler struct attribute. A named 'compiler' library
exposes the compiler's real types (layout-welded via extern(.zig), offsets
queried from the Zig type at compiler-build time + a build-time equality
assertion) and functions (comptime-only, host-call bridged). declare/
define/type_info become sx library code over register_*/find_type; the
projected meta.sx TypeInfo + hand marshaling are deleted; BuildOptions
migrates onto it and #compiler is removed. Includes the safety boundary
(curated export list, guarded mutators, comptime-only), the honest limit
(the ordering law stays, but stops leaking as 'weird stages' — dissolving
the 0141 class), a phased suite-green build order, and the open risks
(union(enum) welding, optional fields, LLVM offset emission).
The compiler concept is declare/define (comptime type construction); the
old "reify" framing is gone from the entire repo.
- Rename: PLAN-REIFY → PLAN-METATYPE, CHECKPOINT-REIFY → CHECKPOINT-METATYPE,
PLAN-POST-REIFY → PLAN-POST-METATYPE (both rewritten around declare/define);
examples 0614/0615/0617 → comptime-metatype-* (+ their expected/ triplets),
headers rewritten.
- Scrub reify from design/execution-evolution-roadmap.md (§7 step 3 contracts,
§8.1, §9 decisions, §10 gates) → declare/define / comptime type construction.
- core.sx prelude pointer + parser.test.zig surface lock updated to the
declare/define builtins (define(handle, info) -> Type; EnumInfo.name).
No behavior change; renamed examples match their renamed snapshots. Full
suite green (673), all unit tests pass. Zero `reify` tokens remain in
src/docs/sx/examples.
Add the async-first execution-model roadmap (comptime JIT spine, colorblind
fibers/Io, atomics, hot-reload) with all seven decisions resolved and
three-way reviewed, and carve the first stream: comptime type_info/reify
(PLAN-REIFY + checkpoint) — the codebase-validated foundation for channel
result types and race's synthesized tagged union.
Drive a bundled `zig` as `zig cc` for the AOT link step, supplying lld + CRT
+ libc (musl/glibc/mingw) so `sx build` produces native binaries with no host
toolchain. Default Linux output is static musl (portable-anywhere).
- src/zig_backend.zig: discover zig ($SX_ZIG / bundled-next-to-exe / PATH);
bundled-vs-PATH provenance gates auto-activation.
- src/target.zig: selectZigLinker + emitZigLinkArgv + zigTargetTriple, dispatched
before the per-OS branches; macOS/Linux/Windows in scope.
- src/ir/emit_llvm.zig: LLVMNormalizeTargetTriple so vendor-less zig triples
(e.g. x86_64-windows-gnu) parse to the correct OS/object format (COFF not ELF).
- src/main.zig: --self-contained / --no-self-contained; linux-musl, linux-musl-arm,
windows-gnu shorthands; de-vendor linux/linux-arm to match the corpus runner.
- examples/1660: Windows Win32 print-42 + exit(0) via kernel32 (ir-only off-Windows).
Auto-activates only for a bundled zig; a PATH-only zig engages under
--self-contained, so native dev/CI builds are never silently rerouted.
Docs: readme Cross-Compilation, design/bundled-zig-link-backend-design.md, current/PLAN-DIST.md.
Moves docs/inline-asm-design.md -> design/inline-asm-design.md (the
internal design record now lives under design/, separate from the
user-facing docs/). Updates all links: current/CHECKPOINT-ASM.md,
current/PLAN-ASM.md, current/PLAN-EXTERN-EXPORT.md (../docs -> ../design)
and docs/inline-assembly.md (same-dir -> ../design).
