I thought VFP was part of the instruction set as of ARMv7. Neon is recommended but options. As I mentioned though, I know of chips in design that don't have Neon, and I suspect also don't have VFP -- but they're ARMv7.. (they also have stripped out the thumb2 part as well..) --Mark > p. > > > > _______________________________________________ > Openembedded-core mailing list > [email protected] > http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-core _______________________________________________ Openembedded-core mailing list [email protected] http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-core
