  /* Do not adjust relocations involving symbols in merged sections.
 
     A reloc patching in the value of some symbol S plus some addend A
     can be produced in different ways:
 
     1) It might simply be a reference to the data at S + A.  Clearly,
        if linker merging shift that data around, the value patched in
        by the reloc needs to be adjusted accordingly.
 
     2) Or, it might be a reference to S, with A added in as a constant
        bias.  For example, given code like this:
 
          static int S[100];
 
          ... S[i - 8] ...
 
        it would be reasonable for the compiler to rearrange the array
        reference to something like:
 
          ... (S-8)[i] ...
 
        and emit assembly code that refers to S - (8 * sizeof (int)),
        so the subtraction is done entirely at compile-time.  In this
        case, the reloc's addend A would be -(8 * sizeof (int)), and
        shifting around code or data at S + A should not affect the
        reloc: the reloc isn't referring to that code or data at all.
 
     The linker has no way of knowing which case it has in hand.  So,
     to disambiguate, we have the linker always treat reloc addends as
     in case 2): they're constants that should be simply added to the
     symbol value, just like the reloc says.  And we express case 1)
     in different way: we have the compiler place a label at the real
     target, and reference that label with an addend of zero.  (The
     compiler is unlikely to reference code using a label plus an
     offset anyway, since it doesn't know the sizes of the
     instructions.)
 
     The simplification being done by gas/write.c:adjust_reloc_syms,
     however, turns the explicit-label usage into the label-plus-
     offset usage, re-introducing the ambiguity the compiler avoided.
     So we need to disable that simplification for symbols referring
     to merged data.
 
     This only affects object size a little bit.  */
