+/* 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. */

+/* The difference between readelf and objdump:
+
+ Both programs are capable of displaying the contents of ELF format files,
+ so why does the binutils project have two file dumpers ?
+
+ The reason is that objdump sees an ELF file through a BFD filter of the
+ world; if BFD has a bug where, say, it disagrees about a machine constant
+ in e_flags, then the odds are good that it will remain internally
+ consistent. The linker sees it the BFD way, objdump sees it the BFD way,
+ GAS sees it the BFD way. There was need for a tool to go find out what
+ the file actually says.
+
+ This is why the readelf program does not link against the BFD library - it
+ exists as an independent program to help verify the correct working of BFD.
+
+ There is also the case that readelf can provide more information about an
+ ELF file than is provided by objdump. In particular it can display DWARF
+ debugging information which (at the moment) objdump cannot. */
