Fix a commit 74e1a04b9787 ("More fixes for reading corrupt ELF files.")
`readelf --version-info' output formatting regression where a dropped
new line caused section header information from the `.gnu.version_d'
version definition section to be printed on the same line as this
section's first entry.
For example with the `mips-linux' target we get:
$ cat ver_def.s
.data
.globl new_foo
.type new_foo, %object
new_foo:
.symver new_foo, foo@@ver_foo
$ cat ver_def.ver
{ global: *foo*; local: *; };
$ as -o ver_def.o ver_def.s
$ ld -e 0 --export-dynamic --version-script=ver_def.ver -o ver_def ver_def.o
$ readelf -V ver_def
Version symbols section '.gnu.version' contains 4 entries:
Addr: 000000000000007e Offset: 0x01007e Link: 2 (.dynsym)
000: 0 (*local*) 2 (ver_foo) 1 (*global*) 2 (ver_foo)
Version definition section '.gnu.version_d' contains 2 entries:
Addr: 0x0000000000000088 Offset: 0x010088 Link: 3 (.dynstr) 000000: Rev: 1 Flags: BASE Index: 1 Cnt: 1 Name: ver_def
0x001c: Rev: 1 Flags: none Index: 2 Cnt: 1 Name: ver_foo
Version definition past end of section
$
Add the new line then, to get:
$ readelf -V ver_def
Version symbols section '.gnu.version' contains 4 entries:
Addr: 000000000000007e Offset: 0x01007e Link: 2 (.dynsym)
000: 0 (*local*) 2 (ver_foo) 1 (*global*) 2 (ver_foo)
Version definition section '.gnu.version_d' contains 2 entries:
Addr: 0x0000000000000088 Offset: 0x010088 Link: 3 (.dynstr)

0x001c: Rev: 1 Flags: none Index: 2 Cnt: 1 Name: ver_foo
Version definition past end of section
$

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.
