bfd/ Add TLS support for 64-bit Sparc ELF. * elf64-sparc.c (sparc64_elf_dyn_relocs, sparc64_elf_link_hash_entry, sparc64_elf_obj_tdata): New structs. (GOT_UNKNOWN, GOT_NORMAL, GOT_TLD_GD, GOT_TLD_IE, sparc64_elf_hash_entry, sparc64_elf_tdata, sparc64_elf_local_got_tls_type): New defines. (sparc64_elf_mkobject): New function. (sparc64_elf_link_hash_table): Add members for dynamic linker sections PLT, RELPLT, DYNBSS, and RELBSS. Add tls_ldm_got uion to track TLS GOT references. Add sym_sec to cache mappings from local sym to section. (link_hash_newfunc): New function. (sparc64_elf_bfd_link_hash_table_create): Rename to sparc64_elf_link_hash_table_create for consistency. Pass link_hash_newfunc to _bfd_elf_link_hash_table_init. (sparc64_elf_create_dynamic_sections): Initialize new section members of sparc64_elf_link_hash_table. Only init srelbss if not-shared. (sparc64_elf_copy_indirect_symbol, sparc64_elf_tls_transition): New functions. (SPARC_NOP): Define. (sparc64_elf_build_plt, sparc64_elf_plt_entry_offset, sparc64_elf_plt_ptr_offset): Delete. (sparc64_plt_entry_build): New function to build PLT entries gradually instread of all at once at the end of linking. (sparc64_elf_check_relocs): Delete dynobj, sgot, and srelgot local vars. Get them from sparc64_elf_hash_table instead. Check early on if r_symndx is in bounds. Handle TLS transitions. Account for TLS GOT references and DF_STATIC_TLS, as needed. For TLS relocs, record the tls_type in either sparc64_elf_local_got_tls_type or sparc64_elf_hash_entry as appropriate. For R_SPARC_TLS_{GD,LDM}_CALL, emit a reference to the __tls_get_addr symbol. For PLT relocs, track references via h->plt.refcount. When R_SPARC_{PC10,PC22,PC_HH22,PC_HM10, PC_LM22} and h not-NULL, set h->non_got_ref. For global data symbol references, count the number of relocations needed for that symbol. For default switch case, don't error, this lets the TLS relocs not explicitly handled by this function get accepted. (sparc64_elf_gc_mark_hook, sparc64_gc_sweep_hook): New functions. (sparc64_elf_adjust_dynamic_symbol): Remove dynobj local var, get it from sparc64_elf_hash_table. Store the real PLT offset in h->plt.offset, and build PLT entries one at a time. Also get .dynbss section pointer from htab. (allocate_dynrelocs, readonly_dynrelocs, sparc64_omit_section_dynsym): New functions. (sparc64_elf_omit_section_dynsym): Use these new functions as helpers. (dtpoff_base, tpoff): New functions. (sparc64_elf_relocate_section): Kill dynobj, sgot, and splt locals, get them from sparc64_elf_hash_table. Handle TLS relocations and refcounting in main relocation loop. (sparc64_elf_finish_dynamic_symbol): Use sparc64_elf_link_hash_table. Build PLT entries as we see them. Handle TLS GOT relocations. (sparc64_elf_finish_dynamic_sections): Get sgot and dynobj from sparc64_elf_hash_table. Initialize only PLT header not all entries since we not build PLT entries one by one. (elf_backend_copy_indirect_symbol, bfd_elf64_mkobject, elf_backend_gc_mark_hook, elf_backend_gc_sweep_hook, elf_backend_can_gc_sections, elf_backend_can_refcount): Define. ld/testsuite/ * ld-selective/sel-dump.exp: Do not exclude sparc64-*. * ld-selective/selective.exp: Likewise. * ld-sparc/sparc.exp: Add {32,64}-bit prefix to test names so we know which one is failing. Run sparc64 TLS tests on multi-arch sparc platforms. * ld-sparc/tls64.sd, ld-sparc/tlssunbin64.dd, ld-sparc/tlssunbin64.rd, ld/testsuite/ld-sparc/tlssunbin64.sd, ld-sparc/tlssunbin64.td, ld-sparc/tlssunnopic64.dd, ld-sparc/tlssunnopic64.rd, ld-sparc/tlssunnopic64.sd, ld-sparc/tlssunpic64.dd, ld-sparc/tlssunpic64.rd, ld-sparc/tlssunpic64.sd, ld-sparc/tlssunpic64.td): Update now that sparc64 ELF does support TLS. |

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.
