             Bug #: 52982
           Summary: add option to select particular linker
    Classification: Unclassified
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: driver
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: f...@redhat.com


If one has both ld and gold installed, gcc gives little help in letting someone
choose one or the other for a particular link job.  (Systemwide relinking a la
alternatives(1), or forcing creation of a temporary -B directory, are not
convenient.)

Please consider adding an option to the driver, akin to -Wl... to allow
overriding of the ld binary being invoked.  Perhaps: gcc -Wl=/bin/ld.gold
(and similar options for -Wa=, -Wp= could make sense).
