   8 # PR 16044 is about a (compile-time-non-local) hidden function symbol,
   9 # entered as an undef reference with a R_CRIS_32_PLT_GOTREL relocation
  10 # referring to a hidden symbol, later defined.  Here, we invalidly
  11 # incremented the h->plt.refcount (from -1) as part of that relocation
  12 # processing.  There are some PLTGOT relocations.  As there are no
  13 # circumstances requiring a PLT entry for this symbol, its PLT entry
  14 # can be eliminated and the PLTGOT relocations can be made to a static
  15 # element in the GOT, relocated with the absolute-to-relative
  16 # R_CRIS_RELATIVE relocation without symbol lookup.  As part of
  17 # eliminating unneeded PLT entries (and PLTGOT to "static" GOT
  18 # elimination), a later pass noticed the inconsistency through an
  19 # assert.
  20 #
  21 # The key points in this dump that may need future adjustments are the
  22 # single dynamic relocation, that the dsofn symbol it points to, is
  23 # local, its absence from the dynamic symbol table and that the
  24 # relocation and symbol values match.
