Probably it needs to turn of FPU exceptions also, sometimes I a lot of floating point division by zero I ran the mctest a few times with different parameters: i386: just compile : 7.9 (both 3.0.2 and 3.1.1) -O4 3.0.2: 8.2 3.1.1: 8.1 -O4 -Opcoreavx2 -Cfavx2 -Cpcoreavx2 3.0.2 8.35 3.1.1 : 12.1 x64: only 3.1.1, sometimes divide by zero (have to set exception mask?) just compile 13.9 -O4 : 19.5 -O4 -Opcoreavx2 -Cfavx2 -Cpcoreavx2 : 19.1 _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
