* Eliminate the static constructors and locks from DynamicLibrary.cpp.Chris Lattner2009-07-071-26/+27
| | | | | | | | | | | | | | | | | | | | This fixes PR4512 and eliminating static ctors is always good. Losing thread safety is unfortunate, but the code is just incredibly poorly designed. If someone is interested, the "right" solution is to split DynamicLibrary.cpp into two separate pieces: a stateless piece in libsystem, and a simple support file in libsupport that has the "state" (e.g. AddSymbol) in managed static objects. Doing this would both fix memory leaks we already have, as well as make the code thread safe again. it would also make sense to move all the unix specific code in System/DynamicLibrary.cpp into System/Unix/DynamicLibrary.inc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74927 91177308-0d34-0410-b5e6-96231b3b80d8
