Comment 2 Saul Wold 2012-08-29 00:50:01 UTC 
The issue seems to be that the poky-tiny has a limited set of DISTRO_FEATURES_LIBC that does not include the libc-libm-big option, without this option the x86-64 build will include the dbl-wrap code instead of the dbl-64 as it likely should.

I think that having DISTRO_FEATURES_LIBC_TINY_x86-64_append = " libc-libm-big"

Sounds reasonable. We can't really measure the delta as it doesn't build currently, but it would be nice to understand the added cost.

Not really, there might be other issues with poky-tiny and x86-64, but I guess someone will get to them at some point!
