Here's a patch proposing a new section on remote debugging with LLDB. This is probably to be merge *after* LLDB 12.0.0 (or equivalent) makes it into FreeBSD, llvm-project commit a8bfee2a356a2e70f854bf6d0b364798f4183795 would be the absolute minimal for reliable remote debugging IMHO. PR: 251709

Event TimelineComment Actions Minor fix, then it is good to go.
Comment Actions Updated as requested. Note that this shouldn't be probably pushed yet, as it could confuse users before LLVM 12.0.0 is released. Comment Actions But it does say "... starting with LLDB 12.0.0", so the confusion would be minimal, right? Comment Actions I'm not sure about that. When I read stuff like this I usually think 'I am using the newest version, so that must be it'. However, IIRC there's no release schedule for 12 yet. Comment Actions I'd err more on the side of having the information in the handbook. If it does not work, the user would get in touch with us (or figure out on their own that their local version is not the one described here). Holding things back often leads to things being forgotten, even though they are ready. These introductory sentences with version specific information should help the user. After all, why put any version information in there? If LLDB 12.0.0 is not released yet, people just have to wait. Comment Actions Looks good to me on the doc side, and I agree with @bcr regarding landing it sooner than later, since the required LLDB version is already included. I will help land this change, thanks again for the submission ;) Comment Actions Included in the document you mean, not included in FreeBSD, right? That said, I'm also on board with getting it in sooner rather than later, based on the assumption that:
Comment Actions At the moment I don't see how this can work with the FreeBSD and LLVM release schedules. The FreeBSD schedule as proposed by gjb is: head slush: January 8, 2021 KBI freeze: January 8, 2021 stable/13 branch: January 22, 2021 releng/13.0 branch: February 5, 2021 BETA1 build starts: February 5, 2021 doc/ tree slush: February 5, 2021 [++] BETA2 build starts: February 12, 2021 BETA3 build starts: February 19, 2021 [*] doc/ tree tag: February 19, 2021 [++] RC1 build starts: February 26, 2021 RC2 build starts: March 5, 2021 RC3 build starts: March 12, 2021 [*] RELEASE build starts: March 19, 2021 RELEASE announcement: March 23, 2021 Branch EoL: TBD Whereas on the LLVM mailing list, we just had a small discussion (see https://lists.llvm.org/pipermail/llvm-dev/2020-December/147063.html) about the upcoming 12.0.0 release. I mentioned there that the LLVM releases tend to happen at the end of March and the end of September (though 10.0.1 and 11.0.0 slipped by quite a lot). Realistically, I don't think LLVM 12.0.0 will be released until well after we release FreeBSD 13.0.0. If it is up to me, I would rather merge the upcoming LLVM 11.0.1 into head, and not disrupt things too much between the git transition(s) and the slush period.
Indeed, I'd rather start pointing people to the port instead, to experiment with new features. Comment Actions Yes, I meant included in the document, so that there is only a minimal chance of misunderstanding. I like the idea of offering users a way to experiment with new features if it is not yet available in the system. @mgorny_gentoo.org, could you please briefly mention the port in the doc (a <note> would do)?
Comment Actions Apart from a minor nit that I will fix when committing, this looks good. Thanks again for the submission!
