========= Binutils Maintainers ========= This is the list of individuals responsible for maintenance and update of the GNU Binary Utilities project. This includes the linker (ld), the assembler (gas), the profiler (gprof), a whole suite of other programs (binutils) and the libraries that they use (bfd and opcodes). This project shares a common set of header files with the GCC and GDB projects (include), so maintainership of those files is shared amongst the projects. The home page for binutils is: http://www.gnu.org/software/binutils/binutils.html and patches should be sent to: binutils@sourceware.org with "[Patch]" as part of the subject line. Note - patches to the top level config.guess and config.sub scripts should be sent to: config-patches@gnu.org and not to the binutils lists. Patches to the other top level configure files (configure, configure.ac, config-ml.in) should be sent to the binutils lists, and copied to the gcc and gdb lists as well (gcc-patches@gcc.gnu.org and gdb-patches@sourceware.org). Patches to the libiberty sources should be sent to gcc-patches@gcc.gnu.org. --------- Blanket Write Privs --------- The following people have permission to check patches into the repository without obtaining approval first: Nick Clifton (head maintainer) Ian Lance Taylor Jeff Law Jim Wilson DJ Delorie Alan Modra Michael Meissner Richard Sandiford Jan Beulich GDB global maintainers also have permission to commit and approve patches to the top level files and to those parts of bfd files primarily used by GDB. --------- Maintainers --------- Maintainers are individuals who are responsible for, and have permission to check in changes in, certain subsets of the code. Note that maintainers still need approval to check in changes outside of the immediate domain that they maintain. If there is no maintainer for a given domain then the responsibility falls to the head maintainer (above). If there are several maintainers for a given domain then responsibility falls to the first maintainer. The first maintainer is free to devolve that responsibility among the other maintainers.

Our thanks for all their hard work goes with them. Paul Brook Eric Christopher Jason Eckhardt Mark Kettenis Mei Ligang Arnold Metselaar Mark Mitchell Bernd Schmidt Svein Seldal Martin Schwidefsky --------- CGEN Maintainers ------------- CGEN is a tool for building, amongst other things, assemblers, disassemblers and simulators from a single description of a CPU. It creates files in several of the binutils directories, but it is mentioned here since there is a single group that maintains CGEN and the files that it creates. If you have CGEN related problems you can send email to; cgen@sourceware.org The current CGEN maintainers are: Doug Evans, Frank Eigler --------- Write After Approval --------- Individuals with "write after approval" have the ability to check in changes, but they must get approval for each change from someone in one of the above lists (blanket write or maintainers). [It's a huge list, folks. You know who you are. If you have the *ability* to do binutils checkins, you're in this group. Just remember to get approval before checking anything in.] ------------- Obvious Fixes ------------- Fixes for obvious mistakes do not need approval, and can be checked in right away, but the patch should still be sent to the binutils list. The definition of obvious is a bit hazy, and if you are not sure, then you should seek approval first. Obvious fixes include fixes for spelling mistakes, blatantly incorrect code (where the correct code is also blatantly obvious), and so on. Obvious fixes should always be small, the larger they are, the more likely it is that they contain some un-obvious side effect or consequence. Obvious fixes should not be "legally significant", as defined here: https://www.gnu.org/prep/maintain/maintain.html#Legally-Significant -------- Patches and Copyright --------- If a patch is non-obvious, its copyright must be considered. There are two ways to handle this. The first is to assign the copyright of the FSF. This ensures that if problems with the authorship of the patch arise, the FSF will be able to deal with them. The list of already assigned copyrights can be obtained from fencepost.gnu.org in the file: /gd/gnuorg/copyright.list. New copyright assignments can be obtained by completing one of the forms found here and sending it off to the FSF: https://git.savannah.gnu.org/gitweb/?p=gnulib.git;a=tree;f=doc/Copyright The alternative is to sign off the contribution by agreeing to the Developer's Certificate of Origin (version 1.1 or later) and adding a line to the end of the contribution that looks something like this: Signed-off-by: Random J Developer The details of the Developer's Certificate or Origin can be found here: https://developercertificate.org/ --------- Branch Checkins --------- If a patch is approved for check in to the mainline sources, it can also be checked into the current release branch. Normally however only bug fixes should be applied to the branch. New features, new ports, etc, should be restricted to the mainline. (Otherwise the burden of maintaining the branch in sync with the mainline becomes too great). If you are uncertain as to whether a patch is appropriate for the branch, ask the branch maintainer. This is: (cf global maintainers) -------- Testsuites --------------- In general patches to any of the binutils testsuites should be considered generic and sent to the binutils mailing list for approval. Patches to target specific tests are the responsibility the relevant port maintainer(s), and can be approved/checked in by them. Other testsuite patches need the approval of a blanket-write-priveleges person. -------- Configure patches ---------- Patches to the top level configure files (config.sub & config.guess) are not the domain of the binutils project and they cannot be approved by the binutils group. Instead they should be submitted to the config maintainer at: config-patches@gnu.org --------- Creating Branches --------- Anyone with at least write-after-approval access may create a branch to use for their own development purposes. In keeping with FSF policies, all patches applied to such a branch must come from people with appropriate copyright assignments on file. All legal requirements that would apply to any other contribution apply equally to contributions on a branch. Before creating the branch, you should select a name for the branch of the form: binutils-- where "org" is the initials of your organization, or your own initials if you are acting as an individual. For example, for a branch created by The GNUDist Company, "tgc" would be an appropriate choice for "org". It's up to each organization to select an appropriate choice for "name"; some organizations may use more structure than others, so "name" may contain additional hyphens. Suppose that The GNUDist Company was creating a branch to develop a port of Binutils to the FullMonty processor. Then, an appropriate choice of branch name would be: binutils-tgc-fm A date stamp is not required as part of the name field, but some organizations like to have one. If you do include the date, you should follow these rules: 1. The date should be the date that the branch was created. 2. The date should be numerical and in the form YYYYMMDD. For example: binutils-tgc-fm_20050101 would be appropriate if the branch was created on January 1st, 2005. Having selected the branch name, create the branch as follows: 1. Check out binutils, so that you have a git checkout corresponding to the initial state of your branch. 2. Create a tag: git tag binutils---branchpoint That tag will allow you, and others, to easily determine what's changed on the branch relative to the initial state. 3. Create and push the branch: git checkout -b binutils---branch git push origin HEAD 4. Document the branch: Add a description of the branch to binutils/BRANCHES, and check that file in. All branch descriptions should be added to the HEAD revision of the file; it doesn't help to modify binutils/BRANCHES on a branch! Please do not commit any patches to a branch you did not create without the explicit permission of the person who created the branch. Copyright (C) 2012-2023 Free Software Foundation, Inc.
