* elf-bfd.h (eh_cie_fde): Add u.cie. Document how u.fde.cie_inf changes when removed == 0. (eh_frame_hdr_info): Add parsed_eh_frames. (_bfd_elf_begin_eh_frame_parsing): Declare. (_bfd_elf_parse_eh_frame): Declare. (_bfd_elf_end_eh_frame_parsing): Declare. * elf-eh-frame.c (_bfd_elf_begin_eh_frame_parsing): New function. (_bfd_elf_parse_eh_frame): New function, split out from _bfd_elf_discard_section_eh_frame. Make a first pass through the buffer to calculate the number of entries and CIEs. Allocate memory for them before the main loop. Replace current extended cie representation with a pair of pointers, one to the local eh_cie_fde and one to the full struct cie. Allocate a separate array of struct cies if not merging. Merge CIEs during the main loop and set up each u.cie.merged field. Point an FDE's cie_inf field directly at the local CIE. Initially assume that all entries should be removed. (_bfd_elf_end_eh_frame_parsing): New function. (_bfd_elf_discard_section_eh_frame): Assume that the section has already been parsed. Use a separate pass to mark entries that need to be kept. Use the u.cie.merged field to track a CIE's group representative. * elflink.c (bfd_elf_discard_info): Call _bfd_elf_parse_eh_frame before _bfd_elf_discard_section_eh_frame. Wrap loop with calls to _bfd_elf_begin_eh_frame_parsing and _bfd_elf_end_eh_frame_parsing.
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.
