    > [builtins] Embed builtins into the binary
    >
    > This embeds code for off-heap-safe builtins into the binary. Actual
    > execution of embedded code is not implemented yet.
    >
    > The embedded file has the following format:
    >
    > namespace v8 {
    > namespace internal {
    >
    > namespace {
    >
    > V8_EMBEDDED_TEXT_HEADER(v8_embedded_blob_)
    > __asm__( /* builtin offsets and lengths */ );
    > __asm__(V8_ASM_LABEL("Builtins_RecordWrite"));
    > __asm__( /* binary instruction stream */ );
    > /* Repeat for other builtins. */
    >
    > extern "C" const uint8_t v8_embedded_blob_[];
    > static const uint32_t v8_embedded_blob_size_ = /* size in bytes */;
