             Bug #: 14640

           Summary: gas generates broken relocations for symbols with weak

                    defs on microblaze

           Product: binutils

           Version: unspecified

            Status: NEW

          Severity: normal

          Priority: P2

         Component: gas

        AssignedTo: address@hidden

        ReportedBy: address@hidden

    Classification: Unclassified





See this thread for a description of the issue and a patch, which is in

Xilinx's fork of binutils but does not seem to have made it upstream:

Basically, the issue is that gas thinks it can generate a 16-bit relative jump

when there's a local definition of the function, even if that definition is

weak and might be overridden by a strong definition that's outside of the

16-bit jump range. I'm in the process of porting musl libc to microblaze, and

this issue is a show-stopper since we make heavy use of weak definitions.
