For procesors koen mentioned VFP is mandatory
Oh yeah, you're right. Sorry, I didn't read his email carefully enough. The original question, though, was whether VFP is mandatory for the ARMv7-A architecture. Irrespective of what the situation is with A8/A9/A15, Cortex-A5 is still an ARMv7-A processor and hence VFP can't be mandatory for the architecture as a whole. p. _______________________________________________ Openembedded-core mailing list [email protected] http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-core
