Cross platform SSE/MMX capabilities detection
-
I think the title says it all. Is there a way to do this with Qt?
I find it already difficult to do this for windows only (found some obscure asm calls that sometime do the job and most of the time fail)
-
There is no way to check that with Qt.
This is platform and/or processor specific.
I know no other way then to do this in asm :-(
-
Could you advise some asm magical that work on linux? Thanks a lot
-
Again, not really specific to Qt. Probably not going to find a lot of answers here, unfortunately. If so, great, but the best I can suggest is: http://lmgtfy.com/?q=detect+MMX+SSE+linux

I found those one each time I got asm related compilation errors.
In the mean time I found this: http://qt.gitorious.org/qt/qt/blobs/fac68dca46131d63f11c37210834073848f5a93d/src/corelib/tools/qsimd_p.h

Are there any x86 processors without SSE still? Maybe a few antiques that are hardly worth the consideration. All x86 processors, manufactured the last 11 years are at least SSE2 capable.
