URL: http://llvm.org/viewvc/llvm-project?rev=279692&view=rev
Log:
Strip opencl.ocl.version metadata
This should be uniqued when linking, but right now it creates
a lot of metadata spam listing the same version. This should also
probably be reporting the compiled version of the user program,
which may differ from the library. Currently the library IR files report
1.0 while 1.1/1.2 are the default for user programs.
