enabling link time optimizations in package builds
Link time optimizations are an optimization that helps with a single digit percent number optimizing both for smaller size, and better speed. These optimizations are available for some time now in GCC. Link time optimizations are also at least turned on in other distros like Fedora, OpenSuse (two years) and Ubuntu (one year). Details at https://wiki.debian.org/ToolChain/LTO The proposal is to turn on LTO by default on most 64bit release architectures. Not proposing to do this on 32bit architectures because of the limited address space at link time, and up to now nobody tested LTO on 32bit archs. In test rebuilds, there were 373 packages (dd-list in the wiki page) found not to build with link time optimizations for various reasons. These range from easily fixable issues in symbols files to some upstream issues. The idea is to fix as many of these as possible, and then change the packaging for the others to just turn off LTO in the package build. To explicitly turn on LTO for a package build: export DEB_BUILD_MAINT_OPTIONS=optimize=+lto to explicitly disable LTO: export DEB_BUILD_MAINT_OPTIONS=optimize=-lto The idea is to file wishlist bug reports for those 373 packages and then see how far we get, and if it's feasible to already turn on LTO for bookworm. If not, it should be turned on by default for the following release. Matthias

GCC and binutils plans for bullseye
Debian bullseye will be based on a gcc-10 package taken from the gcc-10 upstream branch, and binutils based on a binutils package taken from the 2.35 branch. I'm planning to make gcc-10 the default after gcc-10 (10.2.0) is available (upstream targets mid July). binutils will be updated before making the GCC switch. The GCC 10 switch involves some minor library transitions for D, gccgo, M2, which should be no-brainers. The gnat transition will be handled separately by the debian Ada maintainers. binutils should be pretty stable until the bullseye release, not planning an update to 2.36. GCC 10 should be updated to 10.3, or close to 10.3 (the release date is not yet known, could be Feb 2021). I'd like to get rid off GCC 8 and GCC 9 for the bullseye release. Matthias

Adrian, please could you build gcc-9 -26 or -27 in a testing chroot?
Same procedure as every year: GCC defaults change (GCC 9)
GCC 9 was released earlier this year, it is now available in Debian testing/unstable. I am planning to do the defaults change in mid August, around the time of the expected first GCC 9 point release (9.2.0). There are only soname changes for rather unused shared libraries (libgo) involved, and the gnat defaults change will be handled separately by the Debian Ada maintainers. The fortran module changes look ok according to Alastair McKinstry. The gcc-9 package still ftbfs on kfreebsd-*. We still have local patches for at least the various mips, kfreebsd and hurd targets. Please forward these upstream and make sure that these are applied upstream. powerpcspe support is removed upstream. I will keep pointing the default to GCC 8 for this target. Matthias
gcc-8 and gcc-9 builds using pgo and lto optimization
The recent gcc-8 and gcc-9 uploads to unstable are now built using pgo and lto optimization. Not on all architectures, see debian/rules.defs. On the plus side the compilers are 7-10% faster, however the build time of the compiler is much longer, adding 10-20 hours. If people feel that this isn't worth the extra build time, please file an issue for the package to disable those optimizations. Matthias

The packages are now accepted and the 8u212-b03 upstream version is now uploaded as well. The changes and buildinfo files didn't exist anymore for the powerpc, ppc64, sparc64 and x32 binaries, so if a porter wants to restore those, please rebuild them with manually installed openjdk-8 packages from snapshot.debian.org.

This is an optimistic view. While currently not having any RC issues, we still see mips* specific issues popping up more often than on other release architectures. According to https://gcc.gnu.org/gcc-8/criteria.html there is no mips*-linux* target listed as either primary or secondary platform. As far as I understand the mips porters argue that this is covered by mipsisa64-elf, a bare metal target. I don't agree with this view, because - testing is missing on mips*-linux-* targets. If you look at the gcc-testresults ML, you see only test reports submitted for the Debian GCC packages, nothing else. - A bare metal target is usually only built/used for C and C++. I doubt that other frontends are tested. - Configurations like libgcjit are not tested/used upstream, and not addressed. See #798710. The Debian bug tracking for the MIPS port could be better, I usually need some pings to the MIPS porters to get things forwarded or addressed. To me it looks sometimes that Debian is used for testing by upstream, and for that the mips architectures don't need to be release architectures. Matthias
GCC and binutils updates for buster
GCC 8 is available in testing/unstable, and upstream is approaching the first point release. I am planning to make GCC 8 the default at the end of the week (gdc and gccgo already point to GCC 8). Most runtime libraries built from GCC are already used in the version built from GCC 8, so I don't expect runtime incompatibilities anymore. There is one more transistion involved, bumping the libgfortran version. A pre-release version of binutils 2.31 is in testing now, and the final 2.31 release in unstable. These are the major versions for the upcoming buster release, still planning updates to a potential GCC 8.3.0 (estimated Jan 2019) release and binutils 2.31.1 release, or doing equivalent updates from the release branches. There are still a bunch of build failures triggered by GCC 8 [1], so fixing these should get some priority now. See [2] for changes in GCC 8, and the porting guide [3]. I'll be at DebCamp for the second half of the week, and at DebConf, so if there is interest for bug squashing sessions, feel free to grab me, and we can schedule such sessions on a short notice. GCC 5 and GCC 6 are going away, and I am planning the same with GCC 7 as soon as there are upstream kernel and glibc releases which are released after the GCC 8.1.0 release from April. The Debian release team lists toolchain support for our release architectures, and according to [4], the amd64, i386, armel, armhf, arm64 architectures are supported as primary architectures, and s390x is supported as a secondary architectures. Some notes on other candidates for release architectures: - armel: The armv4t default isn't used very much anymore, and we had issues in the past. - armhf: While arm-linux-gnueabihf is not explicitly listed as a primary architecture, I'm told that the arm-linux-armeabi triplet covers the hard float variants as well. - ppc64el: Not documented as primary architecture, but according to the backend maintainers the powerpc64-linux-gnu triplet includes the le variant. - mips*: There is no support for any mips-linux target either as a primary or secondary release architecture (only bare metal), which matches the experience with mips specific issues for the past Debian releases. I understand that port maintainers want to have their port included as a release architecture, however it becomes a burden if neither the upstream nor the Debian port maintainers can keep up with the general upstream development. Maybe we need something in between the alternatives of being a release arch or not, having the benefit of packages in testing/stable, but not being supported in a release.

preparing for binutils-2.31
According to [1], binutils 2.31 (currently in experimental) will branch in about a week, and I'll plan to upload the branch version to unstable. Test results are reported to [2], these look reasonable, except for the various mips targets, however as seen in the past, it doesn't make a difference if you wait with the introduction of a new binutils version early or later with the release. These tend to be only fixed as Debian porters report them. Matthias [1] https://sourceware.org/ml/binutils/2018-06/msg00158.html [2] https://sourceware.org/ml/binutils/2018-06/msg00170.html

The patches to configure --with-cpu-32= and --with-cpu-64= are availabe in GCC 6, so we should use them and ensure that the defaults for the sparc/64 and sparc64, and sparc and sparc64/32 targets match. Just forcing ultrasparc for all multilib variants seems to be questionable. Btw, is there any business with the Debian sparc port, or is this just some exercise? Matthias

I haven't looked at this, and probably won't do it for a while. Best thing would be to build a package and check the generated code for both the 32bit and 64bit multilibs.

No, you are not maintaining powerpcspe as a release architecture, and that's something different than building packages for some of the ports architectures. If you can get powerpcspe accepted as a release architecture, then maybe you gain some credibility to maintain another release architecture ;) Matthias

The (uncalled for) toolchain maintainers roll call for stretch
While the Debian Release team has some citation about the quality of the toolchain on their status page, it is not one of the release criteria documented by the release team. I'd like to document the status how I do understand it for some of the toolchains available in Debian. I appreciate that the release criteria are somehow "reset" for the stretch release, and not copied from previous release decisions. GNU toolchain (GCC / binutils) -- GCC upstream has the notation of primary and secondary platforms, with the commitment to fix issues on these platforms [1], [2]. Debian architectures within the set of these platforms are: - aarch64-none-linux-gnu (starting with GCC 7) - arm-linux-gnueabi - i686-pc-linux-gnu - powerpc64-unknown-linux-gnu - x86_64-unknown-linux-gnu - s390x-linux-gnu Release architectures missing in the primary and secondary platforms: - armhf - mips* - powerpc - ppc64el As you see with arm64, new architectures become primary or secondary platforms only after a while, so that may explain the absence of powerpc64le-unknown-linux-gnu. The arm-linux-gnueabi is not that well defined, so it may include the hard float variant as well. However Debian default to armv4t, while the default configuration for upstream is armv5. However with the selected defaults Debian's libstdc++::future module is not complete and causes build failures on this architecture (same for sparc). Uncovered by the upstream primary and secondary platforms are the mips* architectures and powerpc. For the uncovered archs I would expect somehow more and pro-active Debian maintenance, however I fail to see this happen. - see the history of ftbfs on the buildd page of the gcc-snapshot package - see the status of the gcc-6 package for the pre-release uploads - see the number of RC issues for binutils which came up with 2.27, some still open. - Toolchain packages are not watched by porters, and I can't track every regression myself, however this is not done well by porters. On the recent Porter's call I didn't see any toolchain support for the powerpc architecture. For the mips* architectures we apparently have five or more active toolchain maintainers. I very much doubt that view. From my point of view these architecture would be perfect candidates for partial architectures, and until then should be removed from the set of the release architectures. For mips* that shouldn't be no news; please see my comments regarding both the toolchain and buildd status since at least DebConf 12 (release meetings during DebConfs). Java/OpenJDK For the stretch release openjdk-8 will be fine as the default java implementation. For buster, gcj (to be removed in GCC 7) won't be available anymore, and we'll end up with architectures without a java implementation. At the same time I'd like to consider to stop providing OpenJDK zero builds, leaving powerpc and mips* without a java implementation as well (currently not building for openjdk-9). armhf (not armel) and s390x have Hotspot ports underway. Other toolchains - clang/llvm not available on armel since 3.8. - fpc not available on powerpc anymore (may have changed recently) - mono not available more on powerpc Being demoted as a release architecture certainly is not a nice thing, and looking at past demotions, these were not done very coordinated, not allowing builds in the ports archive for some months. It would be good to find some middle-ground such that a port's demotion isn't a final thing, and it has a chance to become a release architecture again, maybe even as a partial architecture if we can define the meaning of such a thing.

As an example I remember having received several complains from e.g. the GCC maintainers in regards to the state of gcc on various ports[1]. Here I would suspect a patch would be sufficient without needing to actually NMU gcc to get the fix in. There are also stuff like the port concerns from DSA that attention. Right. that's not enough. GCC has some primary and some secondary release architectures. Toolchain support for primary architectures in Debian should be waived, for the secondary and other architectures, Debian needs somebody who is maintaining the relationship between Debian and upstream. Surprisingly this is the case for many non-release Debian architectures like kfreebsd, the Hurd, alpha, hppa, m68k, but not for Debian release architectures like s390, sparc, ia64 and mips*. So we really need somebody to care about this, where the port is considered a secondary citizen or no citizen, or we should demote a port to the ports archive.

changing the java default to java7, and dropping java support for some architectures
It's time to change the Java default to java7, and to drop java support on architectures with non-working java7. Patches for the transition to Java7 should be available in the BTS, mostly submitted by James Page. Some may be still lurking around as diffs in Ubuntu packages, apologies for that. There are a few cases, where Java7 is not yet an alternative to Java6, so the transition should not be blocked on these missing bits. However it should be clear that this is an interim solution, and OpenJDK 6 will be removed for jessie. Currently java bindings/packages are built for all architectures, however some architectures still use gcj as the (only available) Java implementation, and some OpenJDK zero ports are non-functional at this point, and Debian porters usually don't care about that. So the architectures to drop java support would be kfreebsd-any, hurd-i386, mips, mipsel, s390, ia64 - kfreebsd may gain java 7 support at some time, however this shouldn't be relied on yet. - hurd never had openjdk support, and afaik, nobody is working on that. - openjdk support for mips and mipsel is currently broken, with several requests for help on debian-mips left unanswered. - I fixed openjdk on s390 for the release, however this architecture is time comsuming to maintain, and again no answers on debian-s390 asking for help. - same experience on ia64, however the zero ports seems to work there. The list of java archs is a bit changing, and to avoid hardcoding this list into every source package, I propose to something similiar like done for the gcj architectures (/usr/share/gcj/debian_defaults). Let the packages be still architecture any, and decide whether to build arch dependent packages on a make macro java_archs. Build dependencies would still need hard-coding of the architecture list, so another idea would be to keep the default-{jre,jdk} packages on all architectures and only use them if the architecture is found in java_archs.

About 50% of the build failures exposed by GCC-4.5 are fixed [1]. I didn't see issues on amd64 and i386, armel (although optimized for a different processor) and powerpc (some object files linked into shared libs had to be built as pic). It looks like kfreebsd-* also made the switch and there's been a request to switch for mips and mipsel. Looking through the bug list for src:gcc-4.5, none of the open issues seem to be specific to the remaining release architectures which haven't switched yet - i.e. ia64, s390 and sparc. Are you aware of any issues which would preclude switching the default on those architectures? Has there been any discussion with the port maintainers regarding switching? At this point, pretty well after the GCC 4.6.0 release, I would like to avoid switching more architectures to 4.5, but rather get rid of GCC 4.5 to reduce maintenance efforts on the debian-gcc side, even before the multiarch changes go into unstable. I'll make GCC 4.6 the default after the release of GCC 4.5.3, expected later this week, at least on amd64, armel, i386 and powerpc. GCC 4.6 apparently will be used for the next Fedora and OpenSuse releases, and a test rebuild of Ubuntu natty doesn't look too bad (mostly adding new easily fixable C++ build failures). A test rebuild of the unstable archive is still outstanding, but these build failures will have to be fixed anyway. From my point of view it's important to expose GCC 4.6 early in the release cycle to fix issues like #617628 (which are issues in the packages itself) now. With GCC 4.6 comes one soname change, bumping the libobjc version from 2 to 3, which is not easily detachable from the GCC version change. However this change only affects GNUstep, which can be dealt with NMU's, or migration to a new GNUstep version. It's unlikely that GCC 4.5 will be released with wheezy, as the Debian Ada and D maintainers are already working on GCC 4.6 support.

If you do the switch, please also add mips and mipsel, that would avoid you to have to complain in two weeks that these architectures have not yet been switched. Is there a reason not to switch the remaining (release) arches (ia64, kfreebsd-*, sparc, s390)? Maybe hurd-i386 too? I don't know, and I will not invest time to check. If you did check, and if you are confident to fix issues on these architectures, then please tell here. At least for other ports this seems to be possible (s390: Bastian Blank, kfreebsd-*: Aurelian, Petr). I assume you want to release with at least 4.6 on all arches as the default, so I see no point in waiting with switching if there are no known issues. I will not work on toolchain issues specific to these architectures for the wheezy release, so if nobody steps forward, then at least I will not change the default for these architectures.

Note that this is probably the same like modifying the N - ~100 packages, as almost no package respects dpkg-buildflags yet. What's the actual problem --as-needed is trying to solve? why did I explain it in the wiki? The answer is mainly unwanted libraries being linked in as a result of using pkg-config (and various other -config variants), though there are other, lesser, culprits. The pkg-config .pc files for gtk, gnome and other libraries add in many libraries, most of which aren't typically needed. The solution: fix the .pc files! and add more .pc files? Definitely not. I didn't see that many packages where different binaries/libaries were linked with a different set of libraries. Usually this is already introduced by upstreams. Using --as-needed is merely papering over the actual root problem. It fixes the symptoms, but it's not addressing the actual cause. The number of packages providing broken .pc files is not large, and the number breaking due to relying on this brokenness is likely just as small. Other libraries being linked unnecessarily can be removed on a per-package basis. lintian is warning about this, so most developers should be aware of the problem. Damaging our toolchain to work around buggy build scripts is wrong; we should just fix the scripts! again, this is not a script/pkgconfig problem only.

any objections from port maintainers to make gcc-4.4 the default?
Besides the open license issue, are there any objections from port maintainers to make GCC-4.4 the default? As a first step that would be a change of the default for C, C++, ObjC, ObjC++ and Fortran. I'm not sure about Java, which show some regressions compared to 4.3. Otoh it's not amymore the default java compiler for all architectures except hurd(?), kfreebsd(?) and hppa. hppa already defaults to 4.4, what about the hurd and kfreebsd?

This will be an important factor for the release team to determine what is going the port is currently using 4.3 as the default, I do plan to make 4.4 the default unless port maintainers object [1]. Ubuntu karmic already uses 4.4 as the default, but as a community port sparc doesn't get the same attention as other ports. Please see [2] for current problems with sparc. I do not plan to invest significant time in fixing build issues on sparc for squeeze. I do commit to prepare binutils and gcc-4.4 for a sparc64 port if this should happen for squeeze.

Re: Sparc release requalification
On 18.08.2009 22:43, Jurij Smakov wrote: Hello, I would like to point out that sparc release requalification is currently placing it in at risk position for squeeze release. The most serious problems with the port are lack of developer involvement (there is currently one active porter/developer known to the release team, Bernd Zeimetz) and the fact that current mixed 64-bit kernel with 32-bit userspace setup is not supported upstream (CC'ing doko for comment). The current configuration for a biarch toolchain defaulting to 32-bit isn't that well supported. The 32-bit compiler defaults to v8 hardware which isn't available anymore. The biarch setup tightly couples v9 and newer processor support to 64-bit, so switching to a 64-bit userland would offer better use of current hardware besides targeting a comparable setup as other distributions. Newer projects like llvm don't target 32-bit sparc anymore, while they do for 64-bit. I did speak with Martin Zobel at Debconf on how to get there, having two proposals: - define a new sparc64 port, and bootstrap this one using the 32bit port. - have an inplace-transition building required library packages for an upgrade as biarch packages and continue to use the current sparc name. For both variants the toolchain is almost in place. glibc and binutils don't need modifications, gcc needs some libraries be built as biarch on sparc. zlib is already built as biarch on sparc. gmp and mpfr are already built as biarch on other archs, ppl and cloog would be good to have, but we could start without the graphite optimizations as well. I can prepare the changes for gcc, but will not help with any other transition work.

OpenJDK Cacao GCJ Java defaults in unstable
Hi, openjdk-6 in unstable is updated to the 6b14 code drop, built from a recent IcedTea snapshot. There are a few regressions in the ports which don't use the hotspot VM, but the Zero VM. Help from porters would be appreciated. There are two new binary packages offering additional JVMs: - openjdk-6-jre-zero: built on amd64 and i386. This is the JVM used by default on the non-hotspot archs (armel, alpha, s390, mips, mipsel, powerpc, m68k?). Maybe useful for debugging issues with the zero JVM on archs which are more accessible. - icedtea-6-jre-cacao: built on alpha, armel, mips, mipsel, s390, i386, amd64, powerpc). The Cacao JVM and JIT is not yet feature complete compared to the hotspot JVM, but is much faster than the Zero JVM and offers an alternative on platforms which don't have the Hotspot JVM. The additional JVM's can be called with java [-cacao|-zero] or for the java tools with tool name [-J-cacao|-J-zero] This is currently a Debian/Ubuntu only option; integration into IcedTea is in progress. To make a JVM the default, make it the first one in /etc/java-6-openjdk/jvm.cfg. GCJ is still the work horse to build and bootstrap OpenJDK. IMO it still does make sense to keep the '-gcj' packages for software which is known to work with GCJ. I plan to have a recent GCJ-4.x release for the next Debian release. Once openjdk-6 moves to testing, I propose to change the default in the default-{jre,jdk} packages to point to the openjdk-6 packages. This works well, except for one thing: packages will be built with -source 1.6 by default, which makes the resulting .class/.jar files unusable with older java versions (1.4 and 1.5). I would like to propose a change in the Debian java policy, that java packages must be built for the version which is sufficient for a sucessful build. The changes are trivial; I already did check in changes for ant and ant build- and runtime dependencies into the debian-java svn. There is currently work-in-progress to extend the Zero JVM with a JIT (called shark). This is still experimental work, currently requires llvm-2.4 (unstable has 2.5). I would welcome feedback from port maintainers about zero/shark. Please consider to join the IcedTea mailing list.

java status on the ports
Besides m68k hopelessly being behind we do have serious problems on alpha, arm and hppa. - on arm, the bytecode compiler (ecj) doesn't produce correct code. there is currently a workaround to build the package on arm using byte-compiled code built on another architecture. Aurelian has more information on that issue. Afaik not a problem on armel. - on alpha, we do have testsuite failures, leading to a non-working interpreter (see http://bugs.debian.org/464156). We can build gcj-4.3 and ecj, but nothing more (if ecj is built with gcj-4.3). - on hppa, we do see bus errors trying to run the interpreter, plus new testsuite failure (see http://bugs.debian.org/464160). Any help to fix these ports is appreciated, having a replacment for gcj on these archs is fine as well. Test results on all other architectures look fine.

Re: G++ 3.2 breakage on sparc
[ok, this is a Debian self made problem, so don't read on ...] The cause is the patch we apply to build a compiler for sparc-linux, supporting -m64 as well.

AFAICT, it tries to compile #include math.h int main() { acosl(0); } That is compiled using g++. I'd be curious whether this compiles; it should not because no prototype is declared for acosl. If it does compile, the reason should be understood; if it is a good reason, the test program should be modified to detect that no prototype is available.

I would like to get information about package builds on architectures other than i386. Please run the testsuite! (Needs dejagnu from project/experimental).
