PR binutils/17512 * dwarf.c (display_block): Do nothing if the block starts after the end of the buffer. (read_and_display_attr_value): Add range checks. (struct Frame_Chunk): Make the ncols and ra fields unsigned. (frame_need_space): Test for an ncols of zero. (read_cie): Fail if the augmentation data extends off the end of the buffer. (display_debug_frames): Add checks for read_cie failing. Add range checks. * coff-h8300.c (rtype2howto): Replace abort with returning a NULL value. * coff-h8500.c (rtype2howto): Likewise. * coff-tic30.c (rtype2howto): Likewise. * coff-z80.c (rtype2howto): Likewise. * coff-z8k.c (rtype2howto): Likewise. * coff-ia64.c (RTYPE2HOWTO): Always return a valid howto. * coff-m68k.c (m68k_rtype2howto): Return a NULL howto if none could be found. * coff-mcore.c (RTYPE2HOWTO): Add range checking. * coff-w65.c (rtype2howto): Likewise. * coff-we32k.c (RTYPE2HOWTO): Likewise. * pe-mips.c (RTYPE2HOWTO): Likewise. * coff-x86_64.c (coff_amd64_reloc): Likewise. Replace abort with an error return. * coffcode.h (coff_slurp_reloc_table): Allow the rel parameter to be unused. * coffgen.c (make_a_section_from_file): Check the length of a section name before testing to see if it is a debug section name. (coff_object_p): Zero out any uninitialised bytes in the opt header. * ecoff.c (_bfd_ecoff_slurp_symbolic_info): Test for the raw source being empty when there are values to be processed. (_bfd_ecoff_slurp_symbol_table): Add range check. * mach-o.c (bfd_mach_o_canonicalize_one_reloc): Likewise. (bfd_mach_o_mangle_sections): Move test for too many sections to before the allocation of the section table. (bfd_mach_o_read_symtab_strtab): If the read fails, free the memory and nullify the symbol pointer. * reloc.c (bfd_generic_get_relocated_section_contents): Add handling of a bfd_reloc_notsupported return value. * versados.c (EDATA): Add range checking. (get_record): Likewise. (process_otr): Check for contents being available before updating them. (versados_canonicalize_reloc): Add range check.
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.
