The .pure->.naked rename (a7fe165) git-mv'd examples 1800-1803 to their
naked names but the perl content edit (abi(.pure) -> abi(.naked) in the
bodies/comments) was never re-staged, so HEAD carried the renamed files
with stale abi(.pure) bodies — which the compiler now rejects ("unknown
ABI"). The working tree had the correct .naked bodies uncommitted; this
commits them so HEAD parses + builds clean.

// Stream B1 (fibers) — x86_64 sibling of 1800: `abi(.naked)` emits a naked
|
|
// function whose body is raw x86_64 asm (returns 42 in eax, then its own `ret`).
|
|
//
|
|
// Lowered via LLVM's `naked` attribute (no prologue/epilogue/frame). x86_64-
|
|
// pinned via `.build`: ir-only on a non-x86 host — the `.ir` snapshot locks the
|
|
// `naked` attribute + the bare asm body (`movl $42, %eax` / `ret`) and the
|
|
// frame-pointer-free attribute set — and runs end-to-end (exit 42) on
|
|
// x86_64-linux. The IR text (the `naked` attribute, the `call void asm`) is
|
|
// target-independent; only the asm string differs from the aarch64 1800.
