Remove un-referred symbols (dangling symbols to which no relocations refer) #120

Open GoogleCodeExporter opened 9 years ago

Drepper [1] though there is a lot of potential for optimizing relocation 
process. Because he observed relocation processing dominates the startup cost 
with more than 50%
  * The process is asymptotically at least O( R + nr). R: #(relative relocations), r: #(named relocations), n: #(participating DSO)
  * The number of DT_NEEDED also affects loading time
  * We can eliminate the number of relocations by removing un-refered symbols. (Both R and r)
