SSE4.2 readyness. GCC vs MSVC. Deathmatch.

GCC 4.3.2 (cygwin) vs MS VC++ 2008 (Windows 7).

First results porting BitMagic Library to Intel Nehalem SSE4.2 instruction set. :-)

  1. Хотя это врядли имеет отношения к причинам возникновения ошибки, но противоречит теме послания.
    "-msse4 -march=core2" никак не связано ни с Nehalem'ом, ни с SSE4.2, увы.
