contrib/ChangeLog:
* gcc-changelog/git_commit.py: Support foo/bar/*: patterns in
wildcard_prefixes locations.
* gcc-changelog/test_email.py: Test it.
* gcc-changelog/test_patches.txt: Add 3 new patches.
The files in this subdirectory are part of the D2 test suite maintained
in the upstream DMD code repository.
contrib/ChangeLog:
* gcc-changelog/git_commit.py (ignored_prefixes): Add
gcc/testsuite/gdc.test/.
This error is wrong, the line is what exceeds LINE_LIMIT characters, the
limit doesn't exceed itself.
contrib/ChangeLog:
* gcc-changelog/git_commit.py (GitCommit.parse_changelog): Fix
grammar.
If a user installs this script as .git/hooks/prepare-commit-msg and then
works on an old branch which doesn't have the mklog.py script, trying to
commit will fail with an error like:
environment: /.../gcc/contrib/mklog.py: No such file or directory
This makes it exit cleanly so it's possible to commit.
contrib/ChangeLog:
* prepare-commit-msg: Do nothing if the mklog.py script isn't
present.
This comment was added in SVN r173410, v850e1-* was added to config.sub
in SVN r174691 (around 2011). So it should no longer apply.
contrib/ChangeLog:
* config-list.mk (LIST): Add v850e1-elf.
Support for crisv32-*-* and cris-*-linux* was removed in git r11-214.
contrib/ChangeLog:
* config-list.mk (LIST): Remove cris-linux, crisv32-elf, and
crisv32-linux.
I've just tested the script and I'm going to install the patch
to all active branches.
contrib/ChangeLog:
* git-backport.py: The script did 'git co HEAD~' when
there was no modified ChangeLog file in a successful
git cherry pick.
Run cherry-pick --continue without editor.
The patch is about to handle situations like seen
in 3ea6977d0f.
contrib/ChangeLog:
* gcc-changelog/git_commit.py: Properly
handle duplicite authors.
* gcc-changelog/test_email.py: New test.
* gcc-changelog/test_patches.txt: New patch.
So far, we expect from a commit that renames a file to contain a
changelog entry only for the new name. For example, after the following
commit:
$ git move foo bar
$ git commit
We expect the following changelog:
* bar: Renamed from foo.
Git does not keep track of renamings, only file deletions and additions.
The display of patches then uses heuristics (with config-dependent
parameters) to try to match deleted and added files in the same commit.
It is thus brittle to rely on this information.
This commit modifies changelog processing so that renames are considered
as a deletion of a file plus an addition of another file. The following
changelog is now expected for the above example:
* foo: Move...
* bar: Here.
contrib/
* gcc-changelog/git_email.py (GitEmail.__init__): Interpret file
renamings as a file deletion plus a file addition.
* gcc-changelog/git_repository.py (parse_git_revisions):
Likewise.
* gcc-changelog/test_email.py: New testcase.
* gcc-changelog/test_patches.txt: New testcase.
This extends the ChangeLog entries parsing machinery to handle entries
that cover multiple files spanning over multiple lines. For instance:
* first_file_patched.c, second_file_patched.c, third_file_patched.c,
fourth_file_patched.c: Do things.
contrib/
* gcc-changelog/git_commit.py (ChangeLogEntry): Handle entries
with multi-line file lists.
* gcc-changelog/test_email.py: New testcase.
* gcc-changelog/test_patches.txt: Likewise.
Currently, running gcc-changelog's unit tests may clutter the output
with tons of warnings such as:
.../contrib/gcc-changelog/git_email.py:40: ResourceWarning: unclosed
file <_io.TextIOWrapper name='/tmp/tmpt5okd4qp.patch' mode='r'
encoding='UTF-8'>
lines = open(self.filename).read().splitlines()
ResourceWarning: Enable tracemalloc to get the object allocation
traceback
This commit fixes these leaks, which restores a clean testsuite output.
contrib/
* gcc-changelog/git_update_version.py: Close file objects after
use.
* gcc-changelog/git_email.py: Likewise.
* gcc-changelog/test_email.py: Likewise.
The patch improves the script based on Jakub's needs,
I'm going to install the patch.
contrib/ChangeLog:
* gcc-changelog/git_update_version.py: Add 2 new options.
I've long introduced ChangeLog entries as "for dir/ChangeLog", a
format adopted by GNU CVS-Utilities some 20 years ago. My commits
have been formatted like this forever.
This patch makes it acceptable for git gcc-verify.
contrib/ChangeLog:
* gcc-changelog/git_commit.py (changelog_regex): Accept optional
'for' prefix.
This patch simplifies (!!!) the logic governing the naming of dump
files and auxiliary output files in the driver, in the compiler, and
in the LTO wrapper. No changes are made to the naming of primary
outputs, there are often ways to restore past behavior, and a number
of inconsistencies are fixed. Some internal options are removed
(-auxbase and -auxbase-strip), sensible existing uses of -dumpdir and
-dumpbase options remain unchanged, additional useful cases are added,
making for what is still admittedly quite complex. Extensive
documentation and testcases provide numerous examples, from normal to
corner cases.
The most visible changes are:
- aux and dump files now always go in the same directory, that
defaults to the directory of the primary output, but that can be
overridden with -dumpdir, -save-temps=*, or, preserving past behavior,
with a -dumpbase with a directory component.
- driver and compiler now have the same notion of naming of auxiliary
outputs, e.g. .dwo files will no longer be in one location while the
debug info suggests they are elsewhere, and -save-temps and .dwo
auxiliary outputs now go in the same location as .su, .ci and
coverage data, with consistent naming.
- explicitly-specified primary output names guide not only the
location of aux and dump outputs: the output base name is also used in
their base name, as a prefix when also linking (e.g. foo.c bar.c -o
foobar creates foobar-foo.dwo and foobar-bar.dwo with -gsplit-dwarf),
or as the base name instead of the input name (foo.c -c -o whatever.o
creates whatever.su rather than foo.su with -fstack-usage). The
preference for the input file base name, quite useful for our
testsuite, can be restored with -dumpbase "". When compiling and
linking tests in the testsuite with additional inputs, we now use this
flag. Files named in dejagnu board ldflags, libs, and ldscripts are
now quoted in the gcc testsuite with -Wl, so that they are not counted
as additional inputs by the compiler driver.
- naming a -dumpbase when compiling multiple sources used to cause
dumps from later compiles to overwrite those of earlier ones; it is
now used as a prefix when compiling multiple sources, like an
executable name above.
- the dumpbase, explicitly specified or computed from output or input
names, now also governs the naming of aux outputs; since aux outputs
usually replaced the suffix from the input name, while dump outputs
append their own additional suffixes, a -dumpbase-ext option is
introduced to enable a chosen suffix to be dropped from dumpbase to
form aux output names.
- LTO dump and aux outputs were quite a mess, sometimes leaking
temporary output names into -save-temps output names, sometimes
conversely generating desirable aux outputs in temporary locations.
They now obey the same logic of compiler aux and dump outputs, landing
in the expected location and taking the linker output name or an
explicit dumpbase overrider into account.
- Naming of -fdump-final-insns outputs now follows the dump file
naming logic for the .gkd files, and the .gk dump files generated in
the second -fcompare-debug compilation get the .gk inserted before the
suffix that -dumpbase-ext drops in aux outputs.

git-check-commit.py does not know about "Reviewed-by",
"Reviewed-on", and "Signed-off-by" lines and hence it
expects those lines which follow the ChangeLog entries
to be indented by a tab.
This commit makes the script skip those lines. No further
processing is attempted because the review information
is not part of the ChangeLogs.
