This patch teaches GlobalStatus to analyze a call that uses the global value as a callee, not as an argument. With this change internalize call handle the common use of linkonce_odr functions. This reduces the number of linkonce_odr functions in a LTO build of clang (checked with the emit-llvm gold plugin option) from 1730 to 60. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193436 91177308-0d34-0410-b5e6-96231b3b80d8
