Rafael Espindola 9718158222 Revert "Add r159136 back now that pr13124 has been fixed." ... This reverts commit r189886. I found a corner case where this optimization is not valid: Say we have a "linkonce_odr unnamed_addr" in two translation units: * In TU 1 this optimization kicks in and makes it hidden. * In TU 2 it gets const merged with a constant that is *not* unnamed_addr, resulting in a non unnamed_addr constant with default visibility. * The static linker rules for combining visibility them produce a hidden symbol, which is incorrect from the point of view of the non unnamed_addr constant. The one place we can do this is when we know that the symbol is not used from another TU in the same shared object, i.e., during LTO. I will move it there. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@189954 91177308-0d34-0410-b5e6-96231b3b80d8		2013-09-04 16:09:01 +00:00
