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.
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_DTPMOD64
+ 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_DTPREL64 relocation on the offset entry. The loader
+ 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.
This function is invoked for each relocation.
The TLS relocations R_AARCH64_TLSGD_{ADR_PREL21,ADD_LO12_NC} and
- R_AARCH64_TLSDESC_{ADR_PAGE,LD64_LO12_NC,ADD_LO12_NC} are
+ 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.
