/* Notes on implementation:

  Thread Local Store (TLS)

  Overview:

  The implementation currently supports both traditional TLS and TLS
  descriptors, but only general dynamic (GD).

  For traditional TLS the assembler will present us with code
  fragments of the form:

  adrp x0, :tlsgd:foo
                           R_AARCH64_TLSGD_ADR_PAGE21(foo)
  add  x0, :tlsgd_lo12:foo
                           R_AARCH64_TLSGD_ADD_LO12_NC(foo)
  bl   __tls_get_addr
  nop

  For TLS descriptors the assembler will present us with code
  fragments of the form:

  adrp  x0, :tlsdesc:foo                      R_AARCH64_TLSDESC_ADR_PAGE21(foo)
  ldr   x1, [x0, #:tlsdesc_lo12:foo]          R_AARCH64_TLSDESC_LD64_LO12(foo)
  add   x0, x0, #:tlsdesc_lo12:foo            R_AARCH64_TLSDESC_ADD_LO12(foo)
  .tlsdesccall foo
  blr   x1                                    R_AARCH64_TLSDESC_CALL(foo)

  The relocations R_AARCH64_TLSGD_{ADR_PREL21,ADD_LO12_NC} against foo
  indicate that foo is thread local and should be accessed via the
  traditional TLS mechanims.

  The relocations R_AARCH64_TLSDESC_{ADR_PAGE21,LD64_LO12_NC,ADD_LO12_NC}
  against foo indicate that 'foo' is thread local and should be accessed
  via a TLS descriptor mechanism.

  The precise instruction sequence is only relevant from the
  perspective of linker relaxation which is currently not implemented.

  The static linker must detect that 'foo' is a TLS object and
  allocate a double GOT entry. The GOT entry must be created for both
  global and local TLS symbols. Note that this is different to none
  TLS local objects which do not need a GOT entry.

  In the traditional TLS mechanism, the double GOT entry is used to
  provide the tls_index structure, containing module and offset
  entries. The static linker places the relocation R_AARCH64_TLS_DTPMOD
  on the module entry. The loader will subsequently fixup this
  relocation with the module identity.

  For global traditional TLS symbols the static linker places an
  R_AARCH64_TLS_DTPREL relocation on the offset entry. The loader
  will subsequently fixup the offset. For local TLS symbols the static
  linker fixes up offset.

  In the TLS descriptor mechanism the double GOT entry is used to
  provide the descriptor. The static linker places the relocation
  R_AARCH64_TLSDESC on the first GOT slot. The loader will
  subsequently fix this up.

  Implementation:

  The handling of TLS symbols is implemented across a number of
  different backend functions. The following is a top level view of
  what processing is performed where.

  The TLS implementation maintains state information for each TLS
  symbol. The state information for local and global symbols is kept
  in different places. Global symbols use generic BFD structures while
  local symbols use backend specific structures that are allocated and
  maintained entirely by the backend.

  The flow:

  elfNN_aarch64_check_relocs()

  This function is invoked for each relocation.

  The TLS relocations R_AARCH64_TLSGD_{ADR_PREL21,ADD_LO12_NC} and
  R_AARCH64_TLSDESC_{ADR_PAGE21,LD64_LO12_NC,ADD_LO12_NC} are
  spotted. One time creation of local symbol data structures are
  created when the first local symbol is seen.

  The reference count for a symbol is incremented.  The GOT type for
  each symbol is marked as general dynamic.

  elfNN_aarch64_allocate_dynrelocs ()

  For each global with positive reference count we allocate a double
  GOT slot. For a traditional TLS symbol we allocate space for two
  relocation entries on the GOT, for a TLS descriptor symbol we
  allocate space for one relocation on the slot. Record the GOT offset
  for this symbol.

  elfNN_aarch64_size_dynamic_sections ()

  Iterate all input BFDS, look for in the local symbol data structure
  constructed earlier for local TLS symbols and allocate them double
  GOT slots along with space for a single GOT relocation. Update the
  local symbol structure to record the GOT offset allocated.

  elfNN_aarch64_relocate_section ()

  Calls elfNN_aarch64_final_link_relocate ()

  Emit the relevant TLS relocations against the GOT for each TLS
  symbol. For local TLS symbols emit the GOT offset directly. The GOT
  relocations are emitted once the first time a TLS symbol is
  encountered. The implementation uses the LSB of the GOT offset to
  flag that the relevant GOT relocations for a symbol have been
  emitted. All of the TLS code that uses the GOT offset needs to take
  care to mask out this flag bit before using the offset.

  elfNN_aarch64_final_link_relocate ()

  Fixup the R_AARCH64_TLSGD_{ADR_PREL21, ADD_LO12_NC} relocations.  */
