The linker SHF_LINK_ORDER section sorting had a number of defects. 1) The ordering was by VMA, which won't work with overlays. LMA is better. 2) Zero size sections can result in two sections at the same LMA/VMA. When only one of the two sections at the same LMA is zero size, that one must be first. 3) Warnings given by elf_get_linked_section_vma won't ever be emitted since elf_object_p warns and excludes objects with zero sh_link on a SHF_LINK_ORDER section. 4) Section offset was adjusted down rather than up by section alignment, possibly creating overlapping sections. 5) Finding the linked section did so the hard way, rather than simply using elf_linked_to_section. * elflink.c (elf_get_linked_section_vma): Delete. (compare_link_order): Use elf_linked_to_section and sort by lma, size, and id. (elf_fixup_link_order): Use size_t variables where appropriate. Make use of elf_linked_to_section. Formatting. Properly align sections.
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.
