This prevent the symbols from being both externally available and hidden, which causes them to be linked incorrectly. This is only a problem when the address of the function is explicitly taken since it will always be inlined otherwise. This patch fixes the issues that caused r285456 to be reverted, and can now be reapplied. llvm-svn: 285531
