Hi all,
I'm exploring compiling a couple of targets in my Genode, base-hw system to use
the hardware fp in the Neon coprocessor on an ARM Cortex A8 SOC, to get some
performance improvement. I can add the CC_OPT line containing -mfloat-abi=hard
and -mfu=neon-vfpv4 to appropreate target.mk. That should result in the Neon fp
unit being called to perform the calculations. If I want use libc math
functions I assume I must recompile libc with the same compile options added.
Are there build variables that allow me to do that to the libc library?
I'm currently building on Genode 15.02.
Thanks for any info.
