[LLVMdev] Bitcast to [0 x Type]*

[Arushi Aggarwal]

Hi,

I see many statements like the one following, with casts to a 0-sized
array.
 %10 = getelementptr inbounds [0 x %struct.Link]* bitcast ([497 x
%struct.Link]* @link_array to [0 x %struct.Link]*), i64 0, i64 %9 ;
<%struct.Link*> [#uses=1]

Why does this happen, and which  transform causes this?
