I have just ported my chess program to Linux (RedHat5.2) and compiled it with egcs. Sadly it is about 30 percent slower than under W98 compiled with MSVC++ 5. I have tried various compiler options, but plain and simple –O –mpentium seems about fastest on my K6. The W98 version of my program relies on the vcinline.h code in crafty to do PopCnt(), FirstOne() and LastOne(). Egcs (GNU assembler) does not seem to understand MS assembly language, so I used x86.s to replace these functions for the Linux version. This does not seem to be main the problem, however, since comparisons using boolean.c from crafty in place of vcinline.h and x86.s give about the same advantage to W98/MSVC++. Has anyone else had a similar experience? Frank BTW if anyone knows where I can get an Xserver for an Ati Rage Fury (Rage 128) AGP card please tell me. I can then run Linux and KDE on my PII 450.
