The current PLT generation code will generate invalid code when the PLT relocation offset exceeds 64k. This fixes the issue by detecting large plt_reloc offsets and generare code sequences to create larger plt relocations. The "large" plt code needs 2 extra instructions to create 32-bit offsets. bfd/ChangeLog: PR 27746 * elf32-or1k.c (PLT_ENTRY_SIZE_LARGE, PLT_MAX_INSN_COUNT, OR1K_ADD, OR1K_ORI): New macros to help with plt creation. (elf_or1k_link_hash_table): New field plt_count. (elf_or1k_link_hash_entry): New field plt_index. (elf_or1k_plt_entry_size): New function. (or1k_write_plt_entry): Update to support variable size PLTs. (or1k_elf_finish_dynamic_sections): Use new or1k_write_plt_entry API. (or1k_elf_finish_dynamic_symbol): Update to write large PLTs when needed. (allocate_dynrelocs): Use elf_or1k_plt_entry_size to account for PLT size. ld/ChangeLog: PR 27746 testsuite/ld-or1k/or1k.exp (or1kplttests): Add tests for linking along with gotha() relocations. testsuite/ld-or1k/gotha1.dd: New file. testsuite/ld-or1k/gotha1.s: New file. testsuite/ld-or1k/gotha2.dd: New file. testsuite/ld-or1k/gotha2.s: New file testsuite/ld-or1k/pltlib.s (x): Define size to avoid link failure. |

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.
