Sorry for letting this languish!

@shahmishal is there any way we can get armv7 Swift images upstream?

Any news on this? It would be nice to finish this up in one way or another. Let me know if there’s anything I can do!

Maybe we just need to generate a Swift 6.0.1 unofficial container for armv7 now? Well, there are a couple of blockers to generating an SDK as was suggested previously:

• I looked at using the swift-sdk-generator to create an SDK but it's simply not ready to be able to generate an SDK for armv7 in its current state. It will require some updates, such as supporting Debian 11 or 12 to grab armv7 debs to generate an SDK. Then, it would need to be able to somehow grab the armv7 build from "somewhere" (maybe locally) and put the files in the correct place. Right now the SDK generator places target .swiftmodules and libraries in the swift.xctoolchain directory, which is not quite right since they should go into the SDK directory for the target!!!
• I had been previously investigating adding support into swiftlang/swift to cross compile for armv7, but ran into quite a few issues and a Swift runtime that didn't actually work properly on the target. Since then this effort has been paused due to other commitments on my end.

However, if we can just use some of the existing swift-armv7 scripts to build Swift 6.0.1 and generate a container, would that be enough to at least get this done? It would be simple enough to update what we have working and generate something that could be used.

Well, we have a working solution here, so unless there is any indication that this solution is not acceptable, I don’t think we need to do anything else.

Regarding the Swift version. This provides 5.10 for armv7, while the other architectures are still on 5.9, so I think that’s fine for now.

Yeah, I don't foresee an issue with the Swift version. If you can bring this up to current main I'm happy enough to merge this as-is.

@Lukasa : I rebased this on main. Some notes:

• I ran into an issue where running the script a second time causes an issue with the 5.9 containers (error: invalid tool type in 'tools' map). It looks like 5.10 leaves some data in the .build directory that 5.9 doesn't like. I didn't see this issue earlier when they were still on 5.8. Removing the .build directory will fix this, so it shouldn't be a big problem. If this is not acceptable (and there's no specific reason that they are still on 5.9), I can update the other containers to 5.10 as well.
• I'm running this on Linux and assume it would be difficult (impossible?) to get the MacOS and iOS builds working, so I disabled these locally. Could you please verify the complete script on your end?
• For the above reason I did not include the result of the script either. I'll leave it to you to either add the updated files to this branch before merging, or just take the new symbols in when you're updating BoringSSL in the future.
