am335x compiler supporting hardware floating point?

Bruno Bittner1

Is there a compiler available that generates hardware floating point instructions? arm-arago-linux-gnueabihf- ? Is there any other way available for taking advantage of hardware floating point in linux?

Hello,

The EZSDK should be moving to a Linaro toolchain supporting hardfp with the next release which should be in the summer.

Regards,

Dave

What kind of trouble will I have on the EZSDK 05.04.01.00 if I were to use a different compiler with that, for instance this one:

https://launchpad.net/linaro-toolchain-binaries/trunk/2012.10 (gcc 4.5.3 vs. 4.7, I believe).

Would I have to rebuild the kernel? Could I rebuild the kernel?

Hello,

I can not say for sure that it would work but you would need to rebuild everything that you use with the new toolchain as the softfp and hardfp ABI's are not compatible so all applications and libraries must be built with the hardfp toolchain.
