| Randy Eckenrode | I wonder if I’m hitting the LLVM 21 codegen bug. | 05:17:48 |
| Randy Eckenrode | Nope, hitting https://github.com/swiftlang/swift/pull/80920#issuecomment-2830656229 | 18:05:40 |
| Randy Eckenrode | I really didn’t want to have to maintain Swift 5.x just to bootstrap Swift 6.x, especially with the 14.4 SDK due for removal in the future. | 18:07:12 |

Hello, Swift!

| Randy Eckenrode | Next is swift-driver and swiftpm. Also, the bootstrap story. | 20:23:55 |
| Randy Eckenrode | One thing I am doing differently is (trying to) build dependencies as packages. I also want to see if I can have actual swift-driver and swift-syntax packages. swiftPackages.swift will just symlink together swiftc and swift-driver. | 20:25:55 |
| Randy Eckenrode | Once I have this working, I want to go back and split out the stdlib into its own package, which should help make cross-compilation possible. It’s not supported currently. | 20:26:45 |
| Randy Eckenrode | I am working on this for 6.2.1, but I plan to land the changes for 5.10.1 first (moving it into the new pattern). 6.2.1 will be a separate PR. | 20:27:38 |
