           Summary: __attribute((flatten)) not supported
           Product: clang
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: -New Bugs

Per summary, __attribute((flatten)) isn't supported at the moment.  From gcc
docs, "For a function marked with this attribute, every call inside this
function will be inlined, if possible."  Implemented in gcc 4.1 (so anything
that uses it will assume clang supports it).

This attribute is used quite a bit in ffmpeg.
