erbsenzaehlerandStéphane Nicolet	d438720a1c	Unify use of -mdynamic-no-pic ... Apply -mdynamic-no-pic in a single place in the Makefile instead of 5 places. Verified on three different Macs: - a MacBook from 2013 - a MacBook running MacOS 10.9.5 - an iMac running MacOS 10.13.3 No functional change.	2018-02-27 00:30:47 +01:00
erbsenzaehlerandMarco Costalba	ca464fc89e	Cleanup Makfile for MacOs ... 1) Explicitly setting the default lib to the system-default is not needed on a Mac. See: http://libcxx.llvm.org/docs/UsingLibcxx.html 2) We do no longer need to exclude bmi2-builds from LTO. See: https://llvm.org/bugs/show_bug.cgi?id=19416 Changes tested and discussed on FishCooking: https://groups.google.com/forum/?fromgroups=#!topic/fishcooking/acUQtKtEzMM No functional change.	2016-11-25 08:46:20 +01:00
erbsenzaehlerandMarco Costalba	2dd24dc4e6	Use popcount intrinsic with Interl compiler ... It seems that icc used our fallback version of popcount. Now use intrinsics. icc version 16.0.2 (gcc version 5.3.0 compatibility) bmi2 compile uname -r 4.5.1-1-ARCH 20xbench gives a nice speedup ./stockfish-icc-master 2161515 +- 34462 ./stockfish-icc-sse42 2260857 +- 50349	2016-05-01 14:18:16 +02:00
erbsenzaehlerandJoona Kiiski	4048bae47b	Use -O3 for all compilers (including ICC) ... There seems to be no benefit from using -fast over -O3 with icc. So use -O3 everywhere. No functional change Resolves #652	2016-04-24 00:55:56 +01:00
