I strongly believe that for building multi-lib or more
generally when building for multiple targets you want multiple
build directories, and in particular the multiple-cmake

the checks once per target.</div>

<div class="">One of the development steps of the new runtime directory

I'm fine if I can invoke cmake once and get multiple library
variants out. If that means that behind-the-scenes, cmake has
multiple build sub-directories, then that's fine by me. On Windows,
this already happens to some degree, as the Visual Studio project is
allowed to switch between Release, Debug, RelWithDebInfo, etc
without re-running cmake.<br class="">

I don’t know if the runtimes you’re building are setup for

have an LLVM installation on the system or a build directory

The nightly builds that my organization produces is generally a
"customer build", and not a "developer build". Stated otherwise, it
doesn't include llvm-config, libclang.a, or any of the other things

wanted to use this particular out-of-tree solution, I would still
need to clone down LLVM and rebuild and reinstall it on occasion.<br class="">

<div class="">In hindsight I probably should have
explained more of my thinking on this with the patch,

now, and answer the questions along the way. I sent a

feedback.</div>
<div class=""><br class="">
</div>
<div class="">In the build system today there is no
strong distinction between ‘projects’ and ‘tools’.
There are a few subtle differences, but I’m not sure
any of them really matter. The differences are:</div>
<div class=""><br class="">
</div>
<div class="">(1) The projects directory is always
configured, tools can be disabled using
LLVM_INCLUDE_TOOLS=Off (projects and tools can both be
individually disabled too)</div>
<div class="">(2) Projects are configured before tools,
so tools can rely on targets being created for
projects (we don’t really use this, and anywhere we
are is probably a bug)</div>
<div class="">(3) Some projects have special handling.
For example test-suite isn’t actually treated as a
project, it has special handling in
LLVM/CMakeLists.txt:727, and Compiler-RT is handled by
clang if you set LLVM_BUILD_EXTERNAL_COMPILER_RT=On.</div>
<div class=""><br class="">
</div>
<div class="">With this in mind I was thinking about the
general usability of our build system. The distinction
between a project and a tool is not very clear. At a
high level I see three different use cases that are
covered by our current projects & tools
directories.</div>
<div class=""><br class="">
</div>
<div class="">(1) Projects that are configured with LLVM</div>
<div class="">(2) Runtime projects that should be
configured using the just-built tools</div>
<div class="">(3) The LLVM test-suite, which is really
just external tests that should be configured and run
with the just-built tools</div>
<div class=""><br class="">
</div>
<div class="">My proposal is that we make the tools
subdirectory the *only* place for projects that fall
into category 1. I don’t think there is any technical
reason to drop an in-tree project into projects over
tools today, and I think we migrating people who are
doing that away from it should be easy.</div>
<div class=""><br class="">
</div>
<div class="">Second I want to add a “runtimes”
directory to LLVM to cover case 2 (see D20992). The
idea behind this is to use common code in LLVM to
support building runtimes. This will allow the full
LLVM toolchain to be visible during configuration. I
will abstract this functionality into an installed
CMake module so that Clang can use it for out-of-tree
clang builds.</div>
<div class=""><br class="">
</div>
<div class="">Lastly we need to give the test-suite a
new home. I’m not super concerned with where we do
that. It could be under tests, it could just be at the
root of the LLVM directory. I don’t think it matters
too much because it is a one-off. Thoughts welcome.</div>
<div class=""><br class="">
</div>
<div class="">My proposed patch makes the runtimes
directory work for Compiler-RT, but it doesn’t yet
handle libcxxabi, libcxx and libunwind. There is some
special case handling between libcxxabi and libcxx
that will need to be handled to make the dependencies
work between the two, and I still need to work that
out.</div>
<div class=""><br class="">
</div>
<div class="">If we want to go with this proposal I
envision the transition being multi-staged:</div>
<div class=""><br class="">
</div>
<div class="">(1) Adding the new functionality, getting
it up and fully working for all runtime projects -
this will involve changes to runtime projects</div>
<div class="">(2) Work with bot maintainers to migrate
bots, and fix any issues that come up</div>
<div class="">(3) Add support for a new secondary
location for the test-suite</div>
<div class="">(4) Set a date for removing the projects
directory, post patches including updated
documentation</div>
<div class="">(5) Remove the projects directory entirely</div>
