Yes, the changes should indeed be present in my current build, and no, no optimizations other than the default optimization settings (-O2 and the like). This is a straight CVS build (MingW/Msys), except for one small patch that does nothing else than allow for more than one .conf file (http://sourceforge.net/tracker/index.php?func … 551&atid=467234), a feature that can be used in combination with DBGL. So, no changes to the emulation itself.

Maybe one of the mods could be so kind to update the 'CVS Builds' sticky and mention this?

Hi woody,

I just saw you checked in the new dynamic core fpu stuff. May I inform you that it doesn't compile currently on msys/mingw32 (gcc 3.4.2) ?! Looks like you forgot to commit a header file:

if g++ -DHAVE_CONFIG_H -I. -I. -I../.. -I../../include -I/usr/local/include/SDL -Dmain=SDL_main -g -O2 -MT core_dyn_x86.o -MD -MP -MF ".deps/core_dyn_x86.Tpo" -c -o core_dyn_x86.o core_dyn_x86.cpp; \
then mv -f ".deps/core_dyn_x86.Tpo" ".deps/core_dyn_x86.Po"; else rm -f ".deps/core_dyn_x86.Tpo"; exit 1; fi

Yes, guess i should add that file as well 😉
Should compile fine if you remove that #define at top of decoder.h

Seems that the fix for this bug fixed a graphical corruption bug (some columns of black pixels) that I'd recently been seeing in one of my old gfx apps. I wasn't completely sure that it ever worked perfectly in dosbox, so I didn't mention it. Thanks for fixing it.

Well it should not happen with the 0.65 release. Everything else is
under development, and likely to still cause bugs, that's why it should
only be used if there's a reason or if you're doing tests.

hmm. Not sure then. ykhwong's latest build has no problem, whereas I get the black lines in 0.65. A mystery 😀

I see. But it shouldn't be affected by those fpu changes (now they should
match the 0.65 release for x86 systems, and the latest addition should
be faster but stability is to be proven).

Ykhwong's builds not only have the latest fpu changes, but also a lot of other patches. For example vasyl's graphics patches which could be a little more influence on that.
