The bfd_coff_backend_data struct should be read-only, the only thing preventing this is that objcopy writes to one of the fields, _bfd_coff_long_section_names. This patch creates a copy of the field in bfd coff_obj_tdata, which makes more sense anyway. When enabling long section names the intent is to do so for a particular bfd, not for all bfds that might happen to be using the target xvec. bfd/ * coffcode.h: Update coff long section name comment. (bfd_coff_set_long_section_names_allowed): Use macro accessor to set flag. (bfd_coff_set_long_section_names_disallowed): Tidy. (coff_backend_info): Return a const pointer. (bfd_coff_std_swap_table, ticoff0_swap_table, ticoff1_swap_table), (bigobj_swap_table): Make const. (bfd_coff_long_section_names): Use tdata copy. (coff_mkobject): Set long_section_names from coff_backend_info. * coff-go32.c (_bfd_go32_mkobject): Likewise. * peicode.h (pe_mkobject): Likewise. * coff-sh.c (bfd_coff_small_swap_table): Make const. * libcoff-in.h (struct coff_tdata): Add long_section_names, reorder fields. * libcoff.h: Regenerate. binutils/ * objcopy.c (set_long_section_mode): Move earlier in file. (copy_object): Call set_long_section_mode here, after setting output format. (copy_file): Don't call set_long_section_mode.
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.
