MIPS n64 ABI has a peculiarity where all relocations are composed of
three, with subsequent relocation types set to R_MIPS_NONE if further
calculation is not required. Example output produced by `readelf' and
`objdump' for such relocations is:
Offset Info Type Sym. Value Sym. Name + Addend
000000000000 000800000002 R_MIPS_32 0000000000000000 foo + 0
Type2: R_MIPS_NONE
Type3: R_MIPS_NONE
and:
OFFSET TYPE VALUE
0000000000000000 R_MIPS_32 foo
0000000000000000 R_MIPS_NONE *ABS*
0000000000000000 R_MIPS_NONE *ABS*
respectively. The presence of these extra R_MIPS_NONE entries is not
relevant for generic or even some MIPS tests, so optionally match them
with the respective dump patterns, also discarding `xfail' annotation
for MIPS/OpenBSD targets from gas/elf/missing-build-notes.d, removing
these regressions:

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.
