34 # Configure LLVM for a Release+Asserts build that only includes the x86_64 backend, uses
35 # libcpp (because that's what WebKit uses), and doesn't depend on either zlib or curses.
36 # In the future it will be appropriate to parameterize what backends should be built (we
37 # only want to build a backend for our current target) and to add more flags to remove
38 # dependencies and features.
40 # FIXME: We need LLVM to have its own sensible story for hiding symbols. But while we
41 # don't have a sensible story, we use a hilarious one: CPPFLAGS=-fvisibility=hidden
