This release use aligns with Intel(r) Composer XE 2013 SP1 Product Update 2 New features * The library can now be built with clang (though wiht some limitations since clang does not support 128 bit floats) * Support for Vtune analysis of load imbalance * Code contribution from Steven Noonan to build the runtime for ARM* architecture processors * First implementation of runtime API for OpenMP cancellation Bug Fixes * Fixed hang on Windows (only) when using KMP_BLOCKTIME=0 llvm-svn: 197914
