I was assuming, or maybe just hoping? that Raspberry Pi (and ARM devices in general) would not suffer from Denormal's disease like Intel processors do. But guess what: Pi's float coprocessor is IEEE 754 compliant and does all denormals by default (can check with attached denorm-test.pd). Bummer! As if one would use an ARM device to calculate the size of a Majorana particle, rather than doing simple dsp. Do we really need to enable PD-BIGORSMALL() checks for this poor little processor? There seems to be something called 'RunFast mode' for Pi's float processor vfpv2, but I see no way how to enable this via gcc. Option -ffast-math is allowed but doesn't do the trick. Can't find an option to set vfpv2 specifically, in gcc docs.
