             Bug #: 11625
           Summary: Excessive inlinine with Os
           Product: clang
           Version: trunk
          Platform: Macintosh
        OS/Version: MacOS X
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: LLVM Codegen
        AssignedTo: unassignedclangbugs at nondot.org

As the codegen shows, clang -Os -flto -m32 -lstdc++ inlines test_function()
even though it is clearly larger than the cost of the call and it is called
more than once.
Even adding -fno-inline -fno-inline-functions options makes no difference.
