Spotted when inspecting gcc testsuite logs, but this already is
covered by the ld-mmix testsuite, it's just that the assert is ignored
since the regexp match is for a substring and not anchored.
With the anchors added but not the bugfix, the ld.log shows that the
asserts cause a non-match as intended:

Gone with the fix of course, leaving just the intended "undefined
reference" like.
I'm not going to add anchors manually for all the "error:" strings in
the test-suite, not even in the mmix parts. Sorry, but I'll just do
it for *these* specific undefined-reference tests.
Just a thought: maybe the run_dump_test "error:" string should
*automatically* get anchor marks prepended and appended for a single
line match as in the patch, "\A[^\n\r]*" prepended and \Z appended
unless either anchor mark or \r or \n is present in the regexp?
Committed.
bfd:
* elf64-mmix.c (mmix_elf_relax_section): Improve accounting for
R_MMIX_PUSHJ_STUBBABLE relocs against undefined symbols.
ld/testsuite:
* testsuite/ld-mmix/undef-1.d, testsuite/ld-mmix/undef-1m.d,
testsuite/ld-mmix/undef-2.d, testsuite/ld-mmix/undef-2m.d: Add
start- and end-anchors to error-string to match just a
single-line error-message.
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.
