Subject: [CrashReproducer] Add -fmodule-cache-path to reproducer script
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f854b042e70fa85a32c8e71301686aab06913217;p=platform%2Fupstream%2Fllvm.git

[CrashReproducer] Add -fmodule-cache-path to reproducer script

The cc1 invocation in the reproducer script should contain a valid path in
-fmodule-cache-path; for that reuse "<name>.cache/module" dir we already
use to dump the vfs and modules.
