             Bug #: 15033
           Summary: option capable of stripping LTO (all sections
                    beginning with .gnu.lto_)
           Product: binutils
           Version: unspecified
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: binutils
        AssignedTo: address@hidden
        ReportedBy: address@hidden
    Classification: Unclassified


I hear that GCC *really* doesn't handle incompatible LTO information well, so I
was trying to figure out how Debian could strip it from the libpython*.a
shipped in their python2.7-dev package [1], and I was quite surprised to find
that objcopy has no suitable option: neither a --remove-sections flag that
takes wildcards, nor even a --strip-lto flag special-cased for these sections.

(Actually, I would want such an option even if GCC could detect and ignore
incompatible LTO information: that stuff is *gigantic*!)
