Subject: [PATCH v3 0/9] RISC-V: Implement TLS Descriptors.
Date: Tue, 28 Nov 2023 17:51:00 +0900	[thread overview]
Message-ID: <20231128085109.28422-1-ishitatsuyuki@gmail.com> (raw)
In-Reply-To: <20230817180852.121628-2-ishitatsuyuki@gmail.com>

This patchset implements TLS Descriptors (TLSDESC) for RISC-V targets, per
the specification (merged) at [1].

Tested on rv64gc for:
- No regression (& passing new tests) in binutils
- No regression in gcc
- No regression in glibc for subdirs=elf
With both -mtls-dialect=desc and trad.

This contribution is made on behalf of Blue Whale Systems, which has
copyright assignment on file with the FSF.

v2: Add changelogs and tests. Minor fixes described in patch messages.
v3: Add relaxation support. This fixes tst-tls1-static in glibc.

Tatsuyuki Ishi (9):
  RISC-V: Fix local GOT and reloc size calculation for TLS.
  RISC-V: Add TLSDESC reloc definitions.
  RISC-V: Add assembly support for TLSDESC.
  RISC-V: Define and use GOT entry size constants for TLS.
  RISC-V: Initial ld.bfd support for TLSDESC.
  RISC-V: Move STATIC_TLS handling into record_tls_type.
  RISC-V: Unify TLS handling in check_relocs.
  RISC-V: Add elf_link_hash_entry to relax_func args.
  RISC-V: Introduce TLSDESC relaxation.
