The current SystemZ back-end only supports the local-exec TLS access model.
This patch adds all required MC support for the other TLS models, which
means in particular:
- Support additional relocation types for
Initial-exec model: R_390_TLS_IEENT
Local-dynamic-model: R_390_TLS_LDO32, R_390_TLS_LDO64,
R_390_TLS_LDM32, R_390_TLS_LDM64, R_390_TLS_LDCALL
General-dynamic model: R_390_TLS_GD32, R_390_TLS_GD64, R_390_TLS_GDCALL
- Support assembler syntax to generate additional relocations
for use with __tls_get_offset calls:
:tls_gdcall:
:tls_ldcall:
The patch also adds a new test to verify fixups and relocations,
and removes the (already unused) FK_390_PLT16DBL/FK_390_PLT32DBL
fixup kinds.
