XCOFF: add support for TLS relocations on hidden symbols
This patch adds support for TLS relocation targeting C_HIDEXT symbols.
In gas, TLS relocations, except R_TLSM and R_TLMSL, must keep the value
of their target symbol.
In ld, it simply ensures that internal TLS symbols are added to the
linker hash table for xcoff_reloc_type_tls.
It also improves the tests made by both.
bfd/ChangeLog:
* coff-rs6000.c (xcoff_howto_table): Fix name of R_TLSML.
(xcoff_reloc_type_tls): Replace the error when h is NULL by
an assert.
(xcoff_complain_overflow_unsigned_func): Adjust comments.
* coff64-rs6000.c (xcoff64_howto_table): Fix name of R_TLSML.
* xcofflink.c (xcoff_link_add_symbols_to_hash_table): New
function.
(xcoff_link_add_symbols): Add C_HIDEXT TLS symbols to the linker
hash table.
gas/ChangeLog:
* config/tc-ppc.c (md_apply_fix): Enable support for TLS
relocation over internal symbols.
* testsuite/gas/ppc/aix.exp: Replace xcoff-tlms by xcoff-tls.
* testsuite/gas/ppc/xcoff-tlsm-32.d: Removed.
* testsuite/gas/ppc/xcoff-tlsm-64.d: Removed.

* testsuite/gas/ppc/xcoff-tls-32.d: New test.
* testsuite/gas/ppc/xcoff-tls-64.d: New test.
* testsuite/gas/ppc/xcoff-tls.s: New test.
ld/ChangeLog:
* testsuite/ld-powerpc/aix52.exp: Improve aix-tls-reloc test.
* testsuite/ld-powerpc/aix-tls-reloc.s: Likewise.
* testsuite/ld-powerpc/aix-tls-reloc-32.d: Removed.
* testsuite/ld-powerpc/aix-tls-reloc-64.d: Removed.
* testsuite/ld-powerpc/aix-tls-reloc-32.dd: New test.
