Re: [swift-dev] [swift-lldb-dev] Switching swift to C++14

Thanks Ben. My apologies for the slow follow up since I was out. I think we can continue to just conditionally enable C++14 for now for building swift in Windows until we figure out a better strategy. > On Jan 8, 2018, at 12:32 PM, Ben Langmuir wrote: > > Hi Ted, > > I've created a PR to rev

Re: [swift-dev] [swift-lldb-dev] Switching swift to C++14

Hi Ted, I've created a PR to revert this: https://github.com/apple/swift/pull/13804 Updating to C++14 broke our Ubuntu 14.04 bots. While those bots are using a new-enough clang, they are still using the system's libstdc++ 4.8 which doesn't include f

Re: [swift-dev] [swift-lldb-dev] Switching swift to C++14

I have no formal objections to switching lldb to C++14. I haven't been following what is in C++14, but presumably it's purely additive? If so then except for bugs this should be a no-op. My only reservation is it seems a little odd to adopt a "use C++14" policy for Swift lldb and not for ll

Re: [swift-dev] [swift-lldb-dev] Switching swift to C++14

Fair enough. We care about swiftc and llbuild building a variety of platforms today — FreeBSD, Rasberry Pi, etc.  My impression is that C++14 is generally supported by both (a) the mininum versions of the distributions we support today and (b) the current versions of the platforms we’d like to

Re: [swift-dev] [swift-lldb-dev] Switching swift to C++14

It wasn’t changed, it has *always* been C++14 since the day we open sourced it. I only investigated the platforms we officially support (Ubuntu 14.04/15.10 at the time, and macOS 10.10+ IIRC). - Daniel > On Dec 19, 2017, at 2:21 PM, Ted Kremenek wrote: > > Daniel, > > When you changed llbui

Re: [swift-dev] [swift-lldb-dev] Switching swift to C++14

Daniel, When you changed llbuild to require C++14, what platforms did you take into account with that change? If you have already done the assessment here it could speed a resolution of a decision. Thanks, Ted > On Dec 13, 2017, at 3:19 PM, Daniel Dunbar via swift-lldb-dev > wrote: > > FWI

Re: [swift-dev] [swift-lldb-dev] Switching swift to C++14

FWIW, llbuild requires C++14. We have to do some minor shenanigans to workaround bugs in libstdc++ on 14.04, and our use is probably minimal, but just throwing that out there. - Daniel > On Dec 13, 2017, at 1:45 PM, Jordan Rose via swift-lldb-dev > wrote: > > No one else has commented on th
