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.

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