/* 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. */
