Two new workstreams:
- ASM: inline assembly — asm { "tmpl", "=r" -> T, "r" = expr, clobbers(.…) },
multi-return tuples; lowers via the existing llvm_api.c (no shim).
- FFI-linkage: add extern/export postfix keywords, migrate every #foreign onto
them, then purge 'foreign' from the tree (end-state invariant).
Drop current/ from .gitignore so plans + checkpoints are tracked normally
(the dir was ignored; only checkpoints had been force-added). Includes
docs/inline-asm-design.md. specs.md change left uncommitted.

sx extern/export + #foreign retirement — Checkpoint (FFI-linkage stream)
Companion to current/PLAN-EXTERN-EXPORT.md — one merged plan: Part A adds
extern/export, Part B migrates #foreign and purges foreign. Update after
every commit, one step at a time per the cadence rule.
Last completed step
None — plan authored, not yet started. (Merged the former EXTERN-EXPORT + FOREIGN-MIGRATION plans into this single plan.)
Current state
Syntax decided + ratified: bare extern/export, postfix in the callconv(.c)
slot, extern ⇒ callconv(.c), library separate. Touch-points mapped — token
token.zig:45,282; parser 1950,3669,316,425,1305; lowering
decl.zig:1123,387,2110,2382,2514; IR/emit already capable (no codegen change).
Export gap = 4 lowering conditions. Part B foreign footprint to purge: 643 lines /
~57 identifiers in src/ + 28 doc lines. End-state invariant: zero foreign in
the live tree (Phase 9.4 gate). No code written.
Next step
Phase 0.0 — add kw_extern/kw_export tokens + keyword-map entries (beside
kw_callconv) + unit lex test. Then 0.1 (parser plumbing, unconsumed), then Phase 1
(extern working). See the plan's "Kickoff prompt" section.
Open decisions
Part A ratified (bare / postfix / ⇒ callconv(.c) / lib-separate). Part B (confirm
before Phase 9): runtime-class rename target — Runtime*Class* (recommended);
historical carve-out — keep issues/*.md provenance, gate the live tree only.
Log
- (init) Plan written; FFI-linkage stream opened.
- (merge) Folded FOREIGN-MIGRATION in as Part B; deleted the split plan + checkpoint.
Known issues
