(IS_ABSOLUTE_RELOC): Define. (struct ppc_link_hash_entry): New. (struct ppc_link_hash_table): New. (ppc_hash_table): Define. (link_hash_newfunc): New function. (ppc64_elf_link_hash_table_create): New function. (create_got_section): New function. (ppc64_elf_create_dynamic_sections): Call create_got_section. Stash pointers to our dynamic sections in hash table. (ppc64_elf_copy_indirect_symbol): New function. (ppc64_elf_check_relocs): Remove DEBUG code. Use short-cuts to dynamic sections. Localise vars. Modify code for refcounts starting from zero. Don't allocate here, or force symbols dynamic. Don't copy all relocs if shared, select ones we need. Add code to track possible copy relocs for non-shared link. (ppc64_elf_gc_mark_hook): Update comment. (ppc64_elf_gc_sweep_hook): Sweep dynrelocs too. (ppc64_elf_adjust_dynamic_symbol): Remove DEBUG code. Rewrite .plt code for reference counting garbage collection. Don't create .plt entries for functions that don't comply with ABI naming convention, and don't allocate .plt space here. Use short-cuts to dynamic sections. If possible, keep dynamic relocations instead of using copy relocs. Remove confused comments. (ppc_adjust_dynindx): Delete. (WILL_CALL_FINISH_DYNAMIC_SYMBOL): Define. (allocate_dynrelocs): New function. (readonly_dynrelocs): New function. (ppc64_elf_size_dynamic_sections): Rewrite. Allocate local .got space here, and call allocate_dynrelocs to allocate space for global .plt, .got and reloc sections. Use short-cuts to dynamic sections. Call readonly_dynrelocs to determine whether we need DT_TEXTREL. Don't generate section symbols here, the generic ELF linker code does it for us. (ppc64_elf_final_link): Call regular ELF backend linker rather than gc variety, since we do our own .got handling. (ppc64_elf_relocate_section): Remove DEBUG code. Make use of dynamic section short-cuts. Localise vars, and delay setting. Handle unknown relocs in main switch statement. Replace ugly complicated tests for unresolvable relocs with a simple direct scheme using "unresolved_reloc" var. Test ELF_ST_VISIBILITY before allowing an undefined sym in a shared lib. Do R_*_DS tests after main switch, when we've set addend. Do non-addend insn tweaks before main swithc. Ignore input_section->vma when calculating reloc offsets as it's always zero. Rewrite dynamic reloc handling. Consolidate R_*_HA handling. Handle more relocs. (ppc64_elf_finish_dynamic_symbol): Remove DEBUG code. Make use of dynamic section short-cuts. Reorganise .plt handling code. Remove confused comments. Take note of ELF_LINK_FORCED_LOCAL. Move expressions out of swap_reloca_out function calls. (ppc64_elf_reloc_type_class): New function. (ppc64_elf_info_to_howto): Move common expression to local var. (ppc64_elf_finish_dynamic_sections): Remove DEBUG code. Make use of dynamic section short-cuts. Don't fiddle with section syms here as the ELF linker does it for us. (elf_backend_can_refcount): Define. (bfd_elf64_bfd_link_hash_table_create): Define. (elf_backend_copy_indirect_symbol): Define. (elf_backend_reloc_type_class): Define. (elf_backend_*, bfd_elf64_bfd_* defines): Sort.
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.
