C bootstrap (phases 0-9):
cmd/wwc, cmd/6c, cmd/6a, cmd/6l, cmd/ww, rt, lib/*.
ww-side self-host (phase 10):
selfhost/cmd/wwc — ww-cgen frontend; bootstrap fixed point.
selfhost/cmd/6a — assembler; byte-identical to C 6a (test 991).
selfhost/cmd/6l — linker w/ archive (.a) support; byte-identical
to C 6l (test 992).
selfhost/cmd/ww — driver (build/run/version); byte-identical to
C ww (test 993).
make test: 15/15. make bootstrap: ww2.s == ww3.s, ww2.o == ww3.o,
ww2 == ww3 byte-identical, with the full ww-tooled chain.

// lib/c/libc — minimal libc bindings. Each declaration is body-less,
|
|
// imported from the C side at link time. The @symbol attribute pins
|
|
// the linker name; without it, the binding name itself is used.
|
|
//
|
|
// These declarations cover the small surface the bootstrap wants:
|
|
// process exit, three io syscalls, and the malloc/free pair. Higher
|
|
// ergonomics live in sibling pure-ww packages.
