   4 Subject: [PATCH 050/160] PowerPC64 pcrel got relocs against local symbols
   5
   6 Not that anyone would want to indirect via the GOT when an address can
   7 be loaded directly with pla, the following:
   8
   9  pld 3,x@got@pcrel
  10 x:
  11
  12 leads to "Internal error in md_apply_fix", because the generic parts
  13 of assembler fixup handling convert the fx_pcrel fixup to one without
  14 a symbol.  Stop that happening.
  15
  16         * config/tc-ppc.c (ppc_force_relocation): Add PLT_PCREL34 and
  17         assorted GOT_PCREL34 relocs.
  18
  19 (cherry picked from commit 49c3ed081fed6b8e2b48fdc48f805f11e4589514)
