   4 Subject: [PATCH 055/160] Re: PowerPC64 pcrel got relocs against local symbols
   5
   6 The last patch wasn't all that shiny.  There are rather a lot more
   7 relocations that can hit the assertion in md_apply_fix if the symbol
   8 is local or absolute.  Fix them all.
   9
  10         * config/tc-ppc.c (ppc_force_relocation): Add all relocs that
  11         expect a symbol in md_apply_fix.  Remove tls pcrel relocs
  12         already covered in general tls match range.
  13
  14 (cherry picked from commit 8b168f1a1e09e337d2a970f204a0230c091bbe58)
