           Summary: GCC 3.3 -O2 gives "used before defined" inlining
                    warnings
           Product: libraries
           Version: trunk
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: minor
          Priority: P2
         Component: Core LLVM classes
        AssignedTo: rspencer at x10sys.com
        ReportedBy: rspencer at x10sys.com


When building optimized, I now get warnings from GCC 3.3 that certain inline
functions in header files are used before they are defined. For example:

/proj/work/llvm/llvm/include/llvm/DerivedTypes.h:416: warning: `void
   llvm::PATypeHandle::addUser()' was used before it was declared inline
/proj/work/llvm/llvm/include/llvm/AbstractTypeUser.h:78: warning: previous
   non-inline declaration here

Whenever building XPS optimized, I always try to remove every warning. Right now
LLVM is the only source of them. 

I'll submit a patch shortly if I can figure out the correct order of use and
definition.
