1 ========= Binutils Maintainers =========
3 This is the list of individuals responsible for maintenance and update
4 of the GNU Binary Utilities project. This includes the linker (ld),
5 the assembler (gas), the profiler (gprof), a whole suite of other
6 programs (binutils) and the libraries that they use (bfd and
7 opcodes). This project shares a common set of header files with the
8 GCC and GDB projects (include), so maintainership of those files is
9 shared amongst the projects.
11 The home page for binutils is:
13 http://www.gnu.org/software/binutils/binutils.html
15 and patches should be sent to:
17 binutils@sourceware.org
19 with "[Patch]" as part of the subject line. Note - patches to the
20 top level config.guess and config.sub scripts should be sent to:
22 config-patches@gnu.org
24 and not to the binutils lists. Patches to the other top level
25 configure files (configure, configure.ac, config-ml.in) should
26 be sent to the binutils lists, and copied to the gcc and gdb
27 lists as well (gcc-patches@gcc.gnu.org and
28 gdb-patches@sourceware.org).
30 Patches to the libiberty sources should be sent to
31 gcc-patches@gcc.gnu.org.
33 --------- Blanket Write Privs ---------
35 The following people have permission to check patches into the
36 repository without obtaining approval first:
38 Nick Clifton <nickc@redhat.com> (head maintainer)
39 Ian Lance Taylor <ian@airs.com>
40 Jeff Law <law@redhat.com>
41 Jim Wilson <wilson@tuliptree.org>
42 DJ Delorie <dj@redhat.com>
43 Alan Modra <amodra@gmail.com>
44 Michael Meissner <gnu@the-meissners.org>
45 Richard Sandiford <rdsandiford@googlemail.com>
46 Jan Beulich <jbeulich@suse.com>
48 GDB global maintainers also have permission to commit and approve
49 patches to the top level files and to those parts of bfd files
50 primarily used by GDB.
52 --------- Maintainers ---------
54 Maintainers are individuals who are responsible for, and have
55 permission to check in changes in, certain subsets of the code. Note
56 that maintainers still need approval to check in changes outside of
57 the immediate domain that they maintain.
59 If there is no maintainer for a given domain then the responsibility
60 falls to the head maintainer (above). If there are several
61 maintainers for a given domain then responsibility falls to the first
62 maintainer. The first maintainer is free to devolve that
63 responsibility among the other maintainers.

153 --------- Past Maintainers -------------
155 These folks have acted as maintainers in the past, but have now
156 moved on to other things. Our thanks for all their hard work
174 --------- CGEN Maintainers -------------
176 CGEN is a tool for building, amongst other things, assemblers,
177 disassemblers and simulators from a single description of a CPU.
178 It creates files in several of the binutils directories, but it
179 is mentioned here since there is a single group that maintains
180 CGEN and the files that it creates.
182 If you have CGEN related problems you can send email to;
186 The current CGEN maintainers are:
188 Doug Evans, Frank Eigler
190 --------- Write After Approval ---------
192 Individuals with "write after approval" have the ability to check in
193 changes, but they must get approval for each change from someone in
194 one of the above lists (blanket write or maintainers).
196 [It's a huge list, folks. You know who you are. If you have the
197 *ability* to do binutils checkins, you're in this group. Just
198 remember to get approval before checking anything in.]
200 ------------- Obvious Fixes -------------
202 Fixes for obvious mistakes do not need approval, and can be checked in
203 right away, but the patch should still be sent to the binutils list.
204 The definition of obvious is a bit hazy, and if you are not sure, then
205 you should seek approval first. Obvious fixes include fixes for
206 spelling mistakes, blatantly incorrect code (where the correct code is
207 also blatantly obvious), and so on. Obvious fixes should always be
208 small, the larger they are, the more likely it is that they contain
209 some un-obvious side effect or consequence.
211 Obvious fixes should not be "legally significant", as defined here:
213 https://www.gnu.org/prep/maintain/maintain.html#Legally-Significant
215 -------- Patches and Copyright ---------
217 If a patch is non-obvious, its copyright must be considered. There
218 are two ways to handle this. The first is to assign the copyright
219 of the FSF. This ensures that if problems with the authorship of the
220 patch arise, the FSF will be able to deal with them.
222 The list of already assigned copyrights can be obtained from
223 fencepost.gnu.org in the file: /gd/gnuorg/copyright.list.
225 New copyright assignments can be obtained by completing one of the
226 forms found here and sending it off to the FSF:
228 https://git.savannah.gnu.org/gitweb/?p=gnulib.git;a=tree;f=doc/Copyright
230 The alternative is to sign off the contribution by agreeing to the
231 Developer's Certificate of Origin (version 1.1 or later) and adding a
232 line to the end of the contribution that looks something like this:
234 Signed-off-by: Random J Developer <random@developer.example.org>
236 The details of the Developer's Certificate or Origin can be found here:
238 https://developercertificate.org/
240 --------- Branch Checkins ---------
242 If a patch is approved for check in to the mainline sources, it can
243 also be checked into the current release branch. Normally however
244 only bug fixes should be applied to the branch. New features, new
245 ports, etc, should be restricted to the mainline. (Otherwise the
246 burden of maintaining the branch in sync with the mainline becomes too
247 great). If you are uncertain as to whether a patch is appropriate for
248 the branch, ask the branch maintainer. This is:
250 (cf global maintainers)
252 -------- Testsuites ---------------
254 In general patches to any of the binutils testsuites should be
255 considered generic and sent to the binutils mailing list for
256 approval. Patches to target specific tests are the responsibility the
257 relevant port maintainer(s), and can be approved/checked in by them.
258 Other testsuite patches need the approval of a blanket-write-priveleges
261 -------- Configure patches ----------
263 Patches to the top level configure files (config.sub & config.guess)
264 are not the domain of the binutils project and they cannot be approved
265 by the binutils group. Instead they should be submitted to the config
268 config-patches@gnu.org
270 --------- Creating Branches ---------
272 Anyone with at least write-after-approval access may create a branch
273 to use for their own development purposes. In keeping with FSF
274 policies, all patches applied to such a branch must come from people
275 with appropriate copyright assignments on file. All legal
276 requirements that would apply to any other contribution apply equally
277 to contributions on a branch.
279 Before creating the branch, you should select a name for the branch of
282 binutils-<org>-<name>
284 where "org" is the initials of your organization, or your own initials
285 if you are acting as an individual. For example, for a branch created
286 by The GNUDist Company, "tgc" would be an appropriate choice for
287 "org". It's up to each organization to select an appropriate choice
288 for "name"; some organizations may use more structure than others, so
289 "name" may contain additional hyphens.
291 Suppose that The GNUDist Company was creating a branch to develop a
292 port of Binutils to the FullMonty processor. Then, an appropriate
293 choice of branch name would be:
297 A date stamp is not required as part of the name field, but some
298 organizations like to have one. If you do include the date, you
299 should follow these rules:
301 1. The date should be the date that the branch was created.
303 2. The date should be numerical and in the form YYYYMMDD.
307 binutils-tgc-fm_20050101
309 would be appropriate if the branch was created on January 1st, 2005.
311 Having selected the branch name, create the branch as follows:
313 1. Check out binutils, so that you have a git checkout corresponding
314 to the initial state of your branch.
318 git tag binutils-<org>-<name>-branchpoint
320 That tag will allow you, and others, to easily determine what's
321 changed on the branch relative to the initial state.
323 3. Create and push the branch:
325 git checkout -b binutils-<org>-<name>-branch
328 4. Document the branch:
330 Add a description of the branch to binutils/BRANCHES, and check
331 that file in. All branch descriptions should be added to the
332 HEAD revision of the file; it doesn't help to modify
333 binutils/BRANCHES on a branch!
335 Please do not commit any patches to a branch you did not create
336 without the explicit permission of the person who created the branch.
