A new addition to the LLVM code-base this week is initial support for IBM's MASS vectorization library.
IBM Mathematical Acceleration Subsystem (MASS) are a set of libraries with optimized versions of frequently-used mathematical functions and vectorized to make use of POWER hardware's high core/thread counts. IBM MASS is of similar nature to say Intel's Math Kernel Library (MKL). Those wanting to learn more about the MASS libraries can do so on IBM.com .
The LLVM code provides initial support for vectorization using the MASS vector library routines when using the -vector-library=MASSV for the LLVM compiler stack.
The review of this IBM MASS vectorization library optional support has been ongoing for a while but now merged . It will be interesting to benchmark when time allows on the Raptor Blackbird / Talos II to see if using this vectorization library makes a meaningful difference at this stage.
This addition is in the Git/SVN code for this fall's LLVM 9.0 release.
