CI bugged?

warning: filesystem: downgrading from version 2020.10-1 to version 2020.02-7
warning: pacman-mirrors: downgrading from version 20201009-1 to version 20201007-1

I think the sourceforge hasn't updated with the new packages yet.

(rebased on master to get some CI changes..)

Upstream changed a bit build process of compiler-rt. It passes for me since I have already built compiler-rt installed in the system.

I've disabled compiler-rt libs that are not built anyway (I don't remember exact issue but I think they require some features not supported by Binutils) for now.
Proper investigation will have to wait until I get time to do it.

[mati865]

Compiler-RT supported architectures: should say Compiler-RT supported architectures: i386, very funny...
Also it detects 3-rd party Python on CI.

[mati865]

Okay using already existing compiler-rt is the only way to have profiler library. I'll update PR later along with few more tweaks to PKGBUILD.

BTW maybe we should consider splitting this PKGBUILD into separate packages?

I looked into this on the past and realized that the build and maintenance would become much more complex without any substantial benefit.

Okay it works but maybe we should uninstall the other Python for other packages?

It'd make easy version bumps a bit more complicated (that can be solved with script) but big upgrades would be easier to work with. Also it'd allow using faster Ninja instead of Make.

Removed shared linking from the description, I accidentally disabled at some point and re-enabling it now causes DEP violation. I guess we have to recompile libcxx first which is not really possible with monolithic PKGBUILD.

For some reason this fails in the autobuilder:

[mati865]

PR builder did succeed 🤔
Either #7157 was the missing part or another update broke the build.

[lazka]

drive by question: that libunwind depends on gcc is probably not on purpose, right?

[mati865]

Yeah, libunwind really depends only on the system libraries.
