We noticed the following two notices are still embedded in build output:
src/kmp_version.c:#define KMP_COPYRIGHT "Copyright (C) 1997-2013, Intel Corporation. All Rights Reserved."
src/libiomp.rc.var: VALUE "LegalCopyright", "Copyright (C) 1997-2013, Intel Corporation. All rights reserved.\0"
Core LLVM binaries don't contain a copyright notice so it's probably best to follow suite here.
Another option might be for individual contributors to each tack their organisations onto the end following a significant contribution -- thoughts?
(This is primarily an aesthetic observation given that copyright for LLVM code is held by the individual contributors.)
