Since https://trac.webkit.org/changeset/195009 FTL JIT JSC tests fails for me on Ubuntu 15.10.
$ export JSC_verboseFTLFailure=true
$ Tools/Scripts/run-javascriptcore-tests --gtk
ERROR: Unexpected exit code: 139
Failed to load LLVM library at libllvmForJSC.so: libLLVM-3.7.so: cannot open shared object file: No such file or directory
Failed to load LLVM library at /usr/local/lib/javascriptcoregtk-4.0/libllvmForJSC.so: /usr/local/lib/javascriptcoregtk-4.0/libllvmForJSC.so: cannot open shared object file: No such file or directory
LLVM can't be initialized.
Have you got any idea what can be the problem and how to fix it?

Of course the lib can be found on its proper place:
WebKitBuild/DependenciesGTK/Root/lib/libLLVM-3.7.so

$ export LD_LIBRARY_PATH=/home/ossy/WebKit/WebKitBuild/DependenciesGTK/Root/lib
fixes this issue ... but I think it should work out-of-the box.
I think the root of the bug is the same as in bug150933.

WebKitBuild/Release/bin/jsc works without setting LD_LIBRARY_PATH
environment variable, but it links to system libs instead of
the proper libs built by jhbuild.

Is run-javascript-core-tests actually entering the JHBuild environment properly?

LLVM based FTL JIT will gone away soon, so it won't be problem with B3 FTL.
