LLVM Clang 13 Performance Is In Great Shape For Intel Xeon "Ice Lake"

John The Ripper's OpenMP-threaded MD5 benchmark was also edging higher on Clang 13.

The OpenMP-threaded GraphicsMagick image manipulation program was also seeing some gains on LLVM Clang 13. GraphicsMagick is one of the programs where it traditionally has held some advantages being compiled under GCC.

But GraphicsMagick for some operations was coming in slower.

For most of the benchmarks carried out, there were slim but consistent differences between the tested compiler versions.
