* Sort the #include lines for tools/...Chandler Carruth2012-12-041-6/+3
| | | | | | | | Again, tools are trickier to pick the main module header for than library source files. I've started to follow the pattern of using LLVMContext.h when it is included as a stub for program source files. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169252 91177308-0d34-0410-b5e6-96231b3b80d8
* libLTO has a bug in that it will keep every symbol if none is needed. We usedRafael Espindola2012-10-261-10/+0
| | | | | | | | | | to hack around this in the gold plugin by deleting a module if no symbol was needed. Unfortunately, the hack is wrong in the case of o module having no visible symbols but still having side effects via static constructors. The bug will have to be fixed in libLTO itself. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166745 91177308-0d34-0410-b5e6-96231b3b80d8
