So with this patch, GCC can be configured using any tuple matching arm-*-linux-*eabi* ... but they will all behave in exactly the same way. Is this the intention?

I would have expected that using the eabihf tuple would actually cause GCC to default to hard-float ...

I had a look in gcc/config.gcc and there is a precedent in mips for setting an ABI feature based on the triplet.

Zhenqiang, could you update the patch so if with_float is not set and the triplet is arm-*-*hf then set with_float to hard?

Something like:

case ${target} in
arm*-*-*hf)
    with_float=${with_float:-hard}
esac

Also drop the uclibc changes. It's up to that community to define a hard float triplet if they want it.

Thanks. I will update it.
