This patch fixes various problems with TLS relocations. 1) Report an error if a symbol has both TLS and normal GOT entries. 2) The GOT entry size calculation was obscure and made use of the fact that a symbol shouldn't have both normal and TLS GOT entries. 3) The second word of a GD GOT entry sometimes omitted a dynamic reloc, which was fine except that doing so makes it impossible for ld.so to differentiate GD and LD entries. Also, a NONE reloc was emitted. 4) Unnecessary relocs were emitted for GOT entries. 5) GOT relocs didn't take note of UNDEFWEAK_NO_DYNAMIC_RELOC. * elf32-hppa.c (enum _tls_type): Move. (struct elf32_hppa_link_hash_entry): Make tls_type a bitfield. (elf32_hppa_check_relocs): Set DF_STATIC_TLS only for shared libraries. Tidy tls_type handling. Set symbol tls_type for GOT_TLS_LDM too. (got_entries_needed, got_relocs_needed): New functions. (allocate_dynrelocs): Use them. (elf32_hppa_size_dynamic_sections): Likewise. (elf32_hppa_relocate_section): Delete bogus FIXME. Formatting. Correct code emitting relocs on GD/IE got entries. Report an error when a symbol has both normal and TLS GOT relocs.
README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
