Clang PGO is broken for Cfish under Sierra (10.12) , still works under ElCapitan (10.11) - at least for me. In the new makefile, "make" will build the non PGO version, "make cpro" will build a PGO version which will be about 7 to 10% faster , depending on your hardware, the day of the month, phase of the moon yada, yada

haha - not quite that fast , using a command line GUI-less interface written by Bob Hyatt that uses centi seconds - given that Stockfish;s fishtesting uses 10 seconds with .1 second increment for STC , this is a 9 second base with a liberal 0.15 second increment

Cfish is a fork of Stockfish written in "C"

Clang PGO is broken for Cfish under Sierra (10.12) , still works under ElCapitan (10.11) - at least for me. In the new makefile, "make" will build the non PGO version, "make cpro" will build a PGO version which will be about 7 to 10% faster , depending on your hardware, the day of the month, phase of the moon yada, yada

Just a quick update - PGO under Sierra is now working. The fix was made by moving to clang ver 3.9 under Macports and making that the default clang. Although I include Ronald's original makefile on github, I compile cFish from a custom makefile that was derived from crafty. Note this line:

Code: Select all

##### live below should be modified reflect your clang directory and version
@/opt/local/libexec/llvm-3.9/bin/llvm-profdata merge -output=engine.profdata *.profraw

The nice feature about this makefile if you have a mac is you just have to type "make cpro" at the command line in the src directory and you will have the fastest stockfish available to run on macOS. Over 5% faster than the C++ version .
