            Bug ID: 231228
           Summary: devel/llvm[4567]0: : CommandLine Error: Option
                    'enable-value-profiling' registered more than once!
           Product: Ports & Packages
           Version: Latest

                OS: Any

In case several OpenCL implementations sharing devel/LLVM > LLVM 3.X are
installed, software compiled with the OpenCL backend will fail with an error
like:

Device open failed, aborting...
: CommandLine Error: Option 'enable-value-profiling' registered more than once!
LLVM ERROR: inconsistency in registered CommandLine options
Nothing to output !

(the error message above has been taken from clinfo, see Bug 231226).

This problem seems to be unresolved in LLVM, although known since a couple of
years for now. See, for instance, Bug 219562, Bug 224584 where I tried to
gather some of the bug reports on LLVM.

In case devel/ocl-icd is installed, graphics/blender seem to fail when compiled
using OpenCL and option CYCLES - calling blender results in the same error as
shown above.

To reproduce the error described here, try to have installed mesa,beignet as
well as devel/clinfo and devel/ocl-icd and/or lang/pocl.

devel/clinfo reveals the problem quickly.

lang/pocl is useless if used with an ICD.

Can someone help on this?

Kind regards,

oh
