Re: Arm toolchain with gcc / newlib / VFP / hard float - can it be done?

That's why I suggested taking a look at the linaro toolchain, as in it
newlib is built so that newlib takes multilib into account. What does
your gcc say when you do:
So this look a bit short... In here I got sth like:
The lines you have are for "default arch", which - as I said - (from
what I know) is ARMv4 (ARM7TDMI etc.), for your chip I guess you should
have sth like (just a guess):
And your GCC can generate code for ARMv5 (it would probably happily
generate code for Cortex-A15 too (; ), it just doesn't have libraries
for it, so you cannot use anything that comes from library (like sqrt(),
printf(), malloc(), ...).
