            Bug ID: 39053
           Summary: always_inline attribute is sometimes ignored at -O3
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Interprocedural Optimizations
          Assignee: unassignedbugs at nondot.org
          Reporter: phosek at chromium.org
                CC: llvm-bugs at lists.llvm.org

We're seeing cases when functions marked with always_inline attribute aren't
inlined when compiling with -O3 but are inline at lower optimization levels.

One such example is basic_ostream& operator<<(basic_ostream&
(*__pf)(basic_ostream&)) in libc++.
