so I gave no further thought on that.
Oh, Xcode. Now that's a large wrinkle in matters. I take it that means
you used "cmake -G Xcode"? I think most people who work on LLVM use
either the "Unix Makefiles" or he "Ninja" backends for
CMake, which do
generate the check destinations needed. The xcode backend would
completely replace any make/ninja files CMake would generate so that
would explain what you're seeing.

Some more people (I think) have a separate xcode build directory
purely for indexing/IDE but do their main builds in a make/ninja
environment.

Anyway, I've just generated an Xcode project myself and (by running
"xcodebuild -list") there does appear to be an "xcodebuild
-target
check" (etc). I've not actually run them because at the moment I only
have access to a laptop that would take quite a while to finish, but I
think that's probably your best bet.

Cheers.

Tim.

Hi Tim,

Thanks again for that. 

I meant to say that did NOT use any terminal command to create the project, I
just ran the CMake app. I mean I didn’t even use the ‘terminal' app for
that.

So, I tried now what you suggested, and in my case, after running xcodebuild
-list, a long list of targets appear, but none with the text “check” in it. I’m
utterly confused on what to try next.

John

Hi Tim,

Anyway, I seem to have managed to make it work. The ‘make' commands do not
work properly after you create a Xcode project with CMake, but the ‘check’
Targets are still there to be run from the Xcode IDE (only as a whole though).

However, the 'llvm-lit' tool still works just fine, so I can just use
that to run sets of tests from the command line.

Thanks for your help!
