I came across a piece of code <code>void *p = &&abc;</code>. What is the significance of <code>&&</code> here? I know about rvalue references but I think <code>&&</code> used in this context is different. What does <code>&&</code> indicate in <code>void *p = &&abc;</code> ?

<code>&&</code> is gcc's extension to get the address of the label defined in the current function. <code>void *p = &&abc</code> is illegal in standard C99 and C++. This compiles with g++.
