            Bug ID: 185461
           Summary: [GTK][JHBuild] LLVM build in broken with GCC 8.1
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit Gtk
          Assignee: webkit-unassigned at lists.webkit.org

While building LLVM 3.7.0 from JHBuild with GCC 8.1 we get a simple casting error:

/home/cadubentzen/Downloads/llvm-3.7.0.src/include/llvm/IR/ValueMap.h:102:31: error: cannot convert ‘const std::unique_ptr<llvm::DenseMap<const llvm::Metadata*, llvm::TrackingMDRef> >’ to ‘bool’ in return
   bool hasMD() const { return MDMap; }

I see two options:
- Add a patch with the explicit cast in JHBuild, pretty easy and no impact in other places;
- Raise LLVM to 3.9.0 (release that had it fixed first, which was in LLVV's SVN at r265828).

I tested that the first solution works and no errors occur in other places during compilation.

But if it's desirable to have a higher LLVM version, we can raise it to 3.9.0.
