It should give some speed improvement so this is expected. I guess you tested 32 bit builds. > For msvc 2008 it went from 21.38 to 23.80 (ST: 13.86). And this is strange. It should not change MSVC results at all. The ASM stack inline functions are available only for BCC and MinGW builds and are used only when native TLS support is not enabled. > So, it's good as is, and MT users not concerned about > Win9x are better to enable for mingw. Yes though it may not work also with some future windows version. In fact we do not know what MS plan to do. It means that checking real code generated by modern MSVC versions can help us to chose "safe" version which will follow MS plans. > [ Question how can mingw be such much better than msvc with > this option? ] This option should not effect MSVC builds so I guess different results are caused by some mistakes or some external events which strongly change the test conditions. best regards, Przemek _______________________________________________ Harbour mailing list (attachment size limit: 40KB) Harbour@harbour-project.org http://lists.harbour-project.org/mailman/listinfo/harbour
