binutils-gdb modified for the FreeChainXenon project
![]() I happened to run readelf on an ELF file created by Guile. readelf complained about invalid values for DW_FORM_strp. At first I assumed this was just a Guile bug, but eu-readelf did the right thing, so I looked a bit deeper. I came across some old Mach-O code to bias some offsets by section addresses. Guile, unlike many ELF writers, sets the address for the various DWARF-related sections, causing this unusual code to be run. This code came from an old commit: 2005-09-30 H.J. Lu <hongjiu.lu@intel.com> * dwarf.c (fetch_indirect_string): Adjust for section address. (process_debug_info): Likewise. (display_debug_loc): Likewise. (display_debug_ranges): Likewise. * objdump.c (mach_o_dwarf_sections): New. (generic_dwarf_sections): Likewise. (check_mach_o_dwarf): Likewise. (dump_dwarf): Call check_mach_o_dwarf. However it was partially reverted here: https://sourceware.org/ml/binutils/2008-11/msg00134.html This patch just completes the reversion. Built and regtested on x86-64 Fedora 18. I also ran the resulting readelf against the Guile-created object with success. I have no way of testing this on Mach-O, so your feedback is solicited. 2013-12-19 Tom Tromey <tromey@redhat.com> * dwarf.c (fetch_indirect_string): Don't bias by section address. (fetch_indexed_string): Likewise. (process_debug_info): Likewise. (display_debug_loc): Likewise. (display_debug_ranges): Likewise. |

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.
