Fix arm32/64 dynamic TLS relocations
arm32: Add a relocation for TLS descriptors (e.g. gcc's
-mtls-dialect=gnu2).
arm64: Add all the dynamic TLS relocations.
Two of the relocations here are obsolete:
- ARM documents R_ARM_SWI24 as an obsolete static relocation without
saying what it did. It's been replaced by R_ARM_TLS_DESC, a dynamic
relocation. We could probably remove it, but I left it because arm32
is old, and I see the macro in other libc's. It's probably analogous
to R_ARM_THM_SWI8, which is also an obsolete relocation reserved for
a future dynamic relocation.
- I couldn't find any ARM documentation at all for
R_AARCH64_TLS_DTPREL32. It seems to have been part of three
relocations:
- R_AARCH64_TLS_DTPREL32 1031
- R_AARCH64_TLS_DTPMOD32 1032
- R_AARCH64_TLS_TPREL32 1033
