/* TL;DR always use it in this file instead when you want to type
   SYMBOL_REFERENCES_LOCAL.

   It's like SYMBOL_REFERENCES_LOCAL, but it returns true for local
   protected functions.  It happens to be same as SYMBOL_CALLS_LOCAL but
   let's not reuse SYMBOL_CALLS_LOCAL or "CALLS" may puzzle people.

   We do generate a PLT entry when someone attempts to la.pcrel an external
   function.  But we never really implemented "R_LARCH_COPY", thus we've
   never supported la.pcrel an external symbol unless the loaded address is
   only used for locating a function to be called.  Thus the PLT entry is
   a normal PLT entry, not intended to be a so-called "canonical PLT entry"
   on the ports supporting copy relocation.  So attempting to la.pcrel an
   external function will just break pointer equality, even it's a
   STV_DEFAULT function:

   $ cat t.c
   #include <assert.h>
   void check(void *p) {assert(p == check);}
   $ cat main.c
   extern void check(void *);
   int main(void) { check(check); }
   $ cc t.c -fPIC -shared -o t.so
   $ cc main.c -mdirect-extern-access t.so -Wl,-rpath=. -fpie -pie
   $ ./a.out
   a.out: t.c:2: check: Assertion `p == check' failed.
   Aborted

   Thus handling STV_PROTECTED function specially just fixes nothing:
   adding -fvisibility=protected compiling t.c will not magically fix
   the inequality.  The only possible and correct fix is not to use
   -mdirect-extern-access.

   So we should remove this special handling, because it's only an
   unsuccessful workaround for invalid code and it's penalizing valid
   code.  */

     assuming we are not so careful, when we link a shared library the
     correlation of .plt and .rela.plt might look like:

                                idx in .plt     idx in .rela.plt
        ext_func1@plt           0               0
        ext_func2@plt           1               1
        ext_func3@plt           2               2
        hidden_ifunc1@plt       3               None: it's in .rela.got
        hidden_ifunc2@plt       4               None: it's in .rela.got
        normal_ifunc1@plt       5       !=      3
        normal_ifunc2@plt       6       !=      4
        local_ifunc@plt         7               None: it's in .rela.got

     Now oops the indices for normal_ifunc{1,2} in .rela.plt were different
     from the indices in .plt :(.  This would break finish_dynamic_symbol
     which assumes the index in .rela.plt matches the index in .plt.

     So let's be careful and make it correct:

                                idx in .plt     idx in .rela.plt

/*  Relax tls le, mainly relax the process of getting TLS le symbolic addresses.
  there are three situations in which an assembly instruction sequence needs to
  be relaxed:
  symbol address = tp + offset (symbol),offset (symbol) = le_hi20_r + le_lo12_r

  Case 1:
  in this case, the rd register in the st.{w/d} instruction does not store the
  full tls symbolic address, but tp + le_hi20_r, which is a part of the tls
  symbolic address, and then obtains the rd + le_lo12_r address through the
  st.w instruction feature.
  this is the full tls symbolic address (tp + le_hi20_r + le_lo12_r).

  before relax:                         after relax:

  lu12i.w   $rd,%le_hi20_r (sym)        ==> (instruction deleted)
  add.{w/d} $rd,$rd,$tp,%le_add_r (sym) ==> (instruction deleted)
  st.{w/d}  $rs,$rd,%le_lo12_r (sym)    ==> st.{w/d}   $rs,$tp,%le_lo12_r (sym)

  Case 2:
  in this case, ld.{w/d} is similar to st.{w/d} in case1.

  before relax:                         after relax:

  lu12i.w   $rd,%le_hi20_r (sym)        ==> (instruction deleted)
  add.{w/d} $rd,$rd,$tp,%le_add_r (sym) ==> (instruction deleted)
  ld.{w/d}  $rs,$rd,%le_lo12_r (sym)    ==> ld.{w/d}   $rs,$tp,%le_lo12_r (sym)

  Case 3:
  in this case,the rs register in addi.{w/d} stores the full address of the tls
  symbol (tp + le_hi20_r + le_lo12_r).

  before relax:                         after relax:

  lu12i.w    $rd,%le_hi20_r (sym)        ==> (instruction deleted)
  add.{w/d}  $rd,$rd,$tp,%le_add_r (sym) ==> (instruction deleted)
  addi.{w/d} $rs,$rd,%le_lo12_r (sym)    ==> addi.{w/d} $rs,$tp,%le_lo12_r (sym)


  For relocation of all old LE instruction sequences, whether it is
  a normal code model or an extreme code model, relaxation will be
  performed when the relaxation conditions are met.

  nomal code model:
  lu12i.w   $rd,%le_hi20(sym)       => (deleted)
  ori       $rd,$rd,le_lo12(sym)    => ori  $rd,$zero,le_lo12(sym)

  extreme code model:
  lu12i.w   $rd,%le_hi20(sym)       => (deleted)
  ori       $rd,$rd,%le_lo12(sym)   => ori  $rd,$zero,le_lo12(sym)
