Assembly can refer to the size of this struct
as <code>reader__size</code> and the offsets of the two fields
as <code>reader_buf</code> and <code>reader_r</code>.
Hence, if register <code>R1</code> contains a pointer to
a <code>reader</code>, assembly can reference the <code>r</code> field
as <code>reader_r(R1)</code>.
