<p>This value only has defined behavior when used as an operand to the
- '<a href="#i_indbr"><tt>indbr</tt></a>' instruction or for comparisons
+ '<a href="#i_indirectbr"><tt>indirectbr</tt></a>' instruction or for comparisons
against null. Pointer equality tests between labels addresses is undefined
behavior - though, again, comparison against null is ok, and no label is
equal to the null pointer. This may also be passed around as an opaque
pointer sized value as long as the bits are not inspected. This allows
