             Bug #: 15300
           Summary: AR/NM/GNU LD and Gold should issue a warning when used
                    on objects with GCC/LLVM LTO data in it and no other
                    symbols
           Product: binutils
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: binutils
        AssignedTo: address@hidden
        ReportedBy: address@hidden
    Classification: Unclassified


To avoid dups of bugs like this
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=56312
where users mistakely call ar/nm/ld without a plugin and gets undefined
symbols, it would be great if the utilities was able to recognize objects only
with LTO symbols and no other object table and issue warning that compilation
is likely going to fail.
