flush-to-zero mode on rpi - Raspberry Pi Forums

hi:
have floating point intensive application crashes randomly when processing floats. might caused denormalized numbers.

flush-to-zero mode on arm set default on rpi? (precission can ignored).
in other case, how can set up?

use gcc cross-toolchain linaro, rpi 2 b+.

thanks.

setting ftz (flush 0 mode).

looks bit 24 in fpscr (just google arm fpscr).

there better way can suggest, try:-

code: select all

asm( "vmsr fpscr,%0" :: "r" (1 << 24) ) 

or similar.

think fpscr set 0 default on linux.

should work pi's, using vfp or neon.
