Local symbols in the indirect symbol table contain the value `INDIRECT_SYMBOL_LOCAL` and the corresponding __pointers entry must contain the address of the target. In r349060, I added support for local symbols in the indirect symbol table, which was checking if the symbol `isDefined` && `!isExternal` to determine if the symbol is local or not. It turns out that `isDefined` will return false if the user of the symbol comes before its definition, and we'll again generate .long 0 which will be the symbol at the adress 0x0. Instead of doing that, use GlobalValue::hasLocalLinkage() to check if the symbol is local. Differential Revision: https://reviews.llvm.org/D66563 llvm-svn: 369671
