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 */;
} // namespace
const uint8_t* DefaultEmbeddedBlob() { return v8_embedded_blob_; }
uint32_t DefaultEmbeddedBlobSize() { return v8_embedded_blob_size_; }
} // namespace internal
} // namespace v8
