Is LLBuild 0.1.x supposed to support Swift 4.2?

[SDGGiesbrecht (Jeremy David Giesbrecht)]

Maybe the LLBuild team has more details about what they do and don’t intend to support?

About reproducible builds

Hello again! We tried with a stable tag 0.4.0 but unfortunately it exhibits a whole other set of issues: error: could not find source files for target(s): llvmDemangle; use the 'path' property in the Swift 4 manifest to set a custom target path

About reproducible builds

Well, 0.4.0 works fine when built with Swift 5.0. It looks like the llbuild folks goofed and their 0.1.1 @swift-4.2 manifest is way out of date. Your error is because it declares an llvmDemangle target which does not actually exist in the file system.

About reproducible builds

The @swift-4.2 manifest is gone on master altogether, so I suspect the real mistake was not so much that the manifest fell behind, but that it wasn’t deleted when Swift 4.2 was no longer supported.
