            Bug ID: 233494
           Summary: LLVM: BUG: Inconsistency in commandline options with
                    multiple OpenCL vendor libraries installed
           Product: Base System
           Version: CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Many People
          Priority: ---
         Component: bin
          Assignee: bugs at FreeBSD.org
          Reporter: ohartmann at walstatt.org

I'd like to refer to this bug which seems to be still open and still present in
all versions of LLVM since LLVM 4.0 (my guess, I did not track that down
exactly).

Since this severe problem has not been solved even for LLVM 7.0, the issue not
being able to use an ICD for multiple platforms available on FreeBSD in cases
the OpenCL backends (lang/pocl (See https://github.com/pocl/pocl/issues/474),
devel/beignet, lang/clover) are all compiled dynamically against the same LLVM
backend. The issue disapperas were the backend is compiled against a different
version of LLVM or statically linked. Both is inacceptable.

I'd like to refer to this LLVM bug:
