Never worse than soft float, sometimes much better. Note that hard float is implied by VFPv3, and by the subject being "armv7hl". The intention is to use the aapcs-vfp binding but the only real debate is whether to use the D16/32 option. That comes down to whether we want to focus on really great A15 plus or be more inclusive of various minimal ARMv7 systems that are already out there today. Perhaps we need a matrix of known capabilities in v7 hardware. I guess that's another wiki page I should create, starting with my Beagle, Panda and Efika systems, but a pointer to AC100 specs would be cool (I found various reviews on it, and wow it's pricey compared to e.g. Efika) :) Jon. _______________________________________________ arm mailing list arm@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/arm
