No, it turned red Friday night/Saturday morning.
Last good build:
http://lab.llvm.org:8011/builders/lldb-x86-win7-msvc/builds/15167
First bad build:
http://lab.llvm.org:8011/builders/lldb-x86-win7-msvc/builds/15168
It went red because of the change to VS2015/Python 3.5.

BTW, I expect that your buildbot has been experiencing the problems
with the
x86 / x64 toolchain for quite some time, because it's not really
relevant to how much memory your machine has, but just that it was
using an x86 toolchain at all. Has it been red for a long time?

I didn't realize there were any other bots building LLDB, so I made
some changes that will default everything to VS2015 and Py3.
BTW, is your builder doing a debug build or a release build? When
doing a debug build clang now requires more memory than can fit in a
4GB address space to link, so using an x86 toolchain won't work
anymore. I forced a change to use the amd64_x86 toolchain, but this
won't work unless the version of python used by buildbot is a 64-bit
Python distro (because Python.exe is what ultimately calls vcvarsall
and cmake and it inherits the environment of the parent).
So I think you will need to do all this as well.

Then maybe we should keep it 2013/py2.7, until llvm requires 2015.

It's Server 2008 R2 technically, which is the server version of Win 7
(same API set, same OS features, etc). So yea, I'm pretty confident
that test coverage is going to be 100% the same across both. It's
just a matter of if you want to have something that you maintain /
have control over, or if you want to test something in a different way than
what we're testing.

Yours is Win Server 2008; ours is Win 7. I don’t know if that matters.

If I remember correctly your bot isn't actually doing anything
differently than my bot
[http://lab.llvm.org:8011/builders/lldb-x86-windows-msvc2015].
If you want you could just remove your bot. If you want to keep it,
then yea getting it on VS2015 and Python 3 would be the best idea.

It looks like our bot,

, has tried to update to Python 3.5 and MSVC 2015, but it can’t find
python or VC. I’ll talk to our buildmiester about it.
Should we run this guy with 2013/py2.7 or 2015/py3.5?

Hi Zachary,
We are still using MSVC 2013 and Python 2.7 to compile LLDB on Windows
for Android Studio and we also have a buildbot what is testing this
configuration (without sending e-mail at the moment) here:
http://lab.llvm.org:8011/builders/lldb-windows7-android
We are in the discussion to decide what is our plan for going forward
both in terms of Visual Studio version and Python version and I expect
that we will make a decision this week. Until then please don't remove
any hack we have in the code because of MSVC 2013 (e.g. alias template
workarounds) and if adding new code then please try not to break MSVC
2013. I will send out an update about our decision hopefully at the end of this
week.
Yea I mentioned already that I'm not planning on removing anything
related to MSVC 2013, just that I'm personally not supporting it.
Which means that if anyone asks for help, or wants to make it work, or
if it breaks accidentally, they're on their own :) I don't even have
MSVC 2013 installed on my machine anymore, so I can't fix any MSVC
2013 specific issues that arise.
Of course if someone else comes along and wants to help, I have no
problem with that, but due to the difficulty of dealing with
incompatibility between Python 2 and MSVC 2015, it's just going to be
up to someone else to continue making that work if they need it.
You mentioned that LLVM plan to bump the minimum version of MSVC to
2015. Do you have any link to the place where they discussed it or do
you know anything about the schedule?
As far as I know the discussion hasn't started yet, but historically
LLVM has always been pretty consistent about bumping the required MSVC version
every 12-18 months. I know some of the Windows people on the LLVM side are
already "unoficially" using MSVC 2015 on a regular basis, and that's
usually a sign that people are getting an early start to see what kind
of issues might be encountered by the general public when bumping the
required version.
