            Bug ID: 25218
           Summary: Unnecessary relocation with __start_* symbols
           Product: new-bugs
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: new bugs
          Assignee: unassignedbugs at nondot.org
          Reporter: rafael.espindola at gmail.com
                CC: llvm-bugs at lists.llvm.org, ruiu at google.com
    Classification: Unclassified

Given

        .section bar, "a"
        .hidden __start_bar
        .long __start_bar - .
        .long __init_array_start - .

We produce a R_X86_64_RELATIVE for "__start_bar - .".

I *think* we do it because the symbol is created too late and by then we have
decided to create a dynamic relocation already.

Gold creates no relocations.
