-  // Relative relocation to an absolute value. This is normally unrepresentable,
-  // but if the relocation refers to a weak undefined symbol, we allow it to
-  // resolve to the image base. This is a little strange, but it allows us to
-  // link function calls to such symbols. Normally such a call will be guarded
-  // with a comparison, which will load a zero from the GOT.
-  // Another special case is MIPS _gp_disp symbol which represents offset
-  // between start of a function and '_gp' value and defined as absolute just
-  // to simplify the code.

   // We set the final symbols values for linker script defined symbols later.
   // They always can be computed as a link time constant.
