[opensuse-factory] LTO in openSUSE:Factory
Hi. We as toolchain team are working on enablement of LTO in Factory: LTO stands for Link Time Optimization and it is a GCC optimization technique that improves speed and reduces size of binaries. According to our measurements, ELF binaries will be about 5% smaller and debug info packages by 15%. Now, there are various interesting packages that have been LTO in Factory right now: libreoffice, MozillaFirefox, python3, gcc9. Our goal is to extend the scope to as many packages as possible. We'll achieve that via a new RPM macro: _lto_cflags. We expect that about 5% of packages will have LTO disabled due to various reasons. A new META bug has been created for that and will link all these packages: https://bugzilla.opensuse.org/show_bug.cgi?id=1133084 I'm also planning to collect all relevant information for package maintainers on the following WIKI page: https://en.opensuse.org/openSUSE:LTO Note that Debian and Gentoo are also trying to adopt LTO in their corresponding ecosystems: https://wiki.debian.org/LTO https://github.com/InBetweenNames/gentooLTO Martin -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

I've got an almost working staging project: https://build.opensuse.org/project/show/openSUSE:Factory:Staging:N Note that I disabled LTO for about 140 packages in the project. My plan is to first disable LTO for the packages that fail. It would be very difficult task to migrate all packages to LTO first. Then we can get LTO enabled in Factory and later the problematic packages can be adopted to LTO. For some legacy stuff it does not make much sense to spend an extra time with the porting. Martin

Memory requirements can be solved by other ways, crashing applications due to symbol conflicts of different libraries not.

I know, according to experiments I've done we don't face the issue. Moreover, GCC 9 was significantly improved and LTO mode is not consuming so much memory. Martin -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

No. Right now we're talking about 15-20 packages that use symbol versioning (out of ~3000). Moreover, LTO is the most beneficial for executables of a reasonable size where scope of exported symbols is limited. On the contrary, libraries have a lot of symbols (functions) exported. Note that we're planning to add support for symber in next GCC release.

Yes. Martin

IIRC symbol-versioning with -Wl,-map should work just fine, just the glibc way of using toplevel asms does not. Hopefully not too many projects copied that way. For C++ restricting visibility is something that works as well and is similarly useful (just w/o the versions).
We need much more shared libraries with symbol versioning then less or LTO ...
Yes.
I think we need more (C++) shared libraries that make their set of exported symbols explicit. Not sure if we really need more libraries with several variants of the same symbol ;) Richard.

Hello. I'm happy to announce that latest ([1]) Tumbleweed release is a first snapshot that uses LTO by default. The snapshot survived the full openQA testing and I've been using the snapshot on both my machines. Users can look forward to smaller and faster binaries. Right now, we've been collecting statistics and we're planning to write a more detail blog post about the benefits. The enablement wouldn't be possible without a great effort of the people who take of openSUSE:Factory. I thank them for the nice cooperation and special thanks goes to DimStar who was very patient with me. We are still expecting a fallout of the change and we'll try to fix the potentially broken package quickly. Another unresolved topic are reproducible builds on which we are cooperating with Bernhard Wiedemann. In order to make the announcement complete, users can expect Chromium package using LTO and a new Firefox release will newly utilize profile guided optimization (PGO).

Reminds me of the Smart Linking feature of Borland Pascal many years ago - around 1995 :-) Basically the link phase would include only code actually used by the programs, not the entire libraries (this required a different object file format with the necessary information). It was thus curious that a helloworld.pas would occupy 2KB when built, while helloworld.c resulted 16 or 30 K binary. I'm hope that LTO succeeds and we can see it in Leap. -- Cheers / Saludos, Carlos E. R. (from 15.0 x86_64 at Telcontar)

LTO flags are injected into Optflags in openSUSE:Factory - so every project building against openSUSE:Factory/{standard,snapshot} has LTO enabled - UNLESS the devel project does some weird stuff to disable it again. In this case, shame on the devel project (I'm not aware of any such project configuration, so this is really just hypothetical) Disabling LTO for the package can be a first test to identify the root cause - but it should only be used as a short term solution, preferably fixing the underlying issue.

That does not work for some reason. It looks the package inherits somehow $optflags from a different package. Martin

As said I only had this issue when using pdns-recursor 4.1.13 on Tumbleweed, but not with 4.2.0. Since 4.2.0 should reach Tumbleweed really soon I don't know whether it's worth the effort. Ciao, Michael.

'soon' was 5 days ago - pdns-recursor 4.2.0 has been part of snapshot 0718 Cheers Dominique

Even better. ;-) (I was confused by package 'pdns-4.1.10' when writing my answer.) Ciao, Michael.

Hello.
I'm happy to announce that latest ([1]) Tumbleweed release is a first snapshot that uses LTO by default. The snapshot survived the full openQA testing and I've been using the snapshot on both my machines. Users can look forward to smaller and faster binaries. Right now, we've been collecting statistics and we're planning to write a more detail blog post about the benefits.
The enablement wouldn't be possible without a great effort of the people who take of openSUSE:Factory. I thank them for the nice cooperation and special thanks goes to DimStar who was very patient with me.
We are still expecting a fallout of the change and we'll try to fix the potentially broken package quickly. Another unresolved topic are reproducible builds on which we are cooperating with Bernhard Wiedemann.
In order to make the announcement complete, users can expect Chromium package using LTO and a new Firefox release will newly utilize profile guided optimization (PGO).

Thanks for the heads up! I was wondering why some of my packages started to fail in OBS, and then I remembered this thread. Disabling LTO as a workaround solved the problem for now. One of the affected upstream already received a github issue, for the other one I will need to package the latest version before submitting one...

Anyone have an issue with wine? After an update at the same time, wine starts with a couple popups with an error. Then the program itself starts and runs. It also happens with winecfg or wineconsole.

The two files each have a top level variable "members", which have an implicit "extern" storage class. Any other translation unit ("file") could reference it, and the linker would try to resolve it. As both both TUs end up in the same binary, the linker has two possibilities for each reference. In this case, probably the best fix is to declare both "members" instances as static.

It's not that easy (at least with my *very* rusty C knowledge), since xpp/ mpptalk.c uses this union from xtalk_raw.c and xtalk_sync.c.

I suggest replacing VeraCrypt with tc-play and zuluCrypt. VeraCrypt’s code quality is extremely poor and the Linux port does not receive a lot of attention.
