When this is enabled, the kernel will support use of 64-bit floating
point registers with binaries using the O32 ABI along with the
of your kernel & potentially improve FP emulation performance by
saying N here.
- If unsure, say Y.
+ Although binutils currently supports use of this flag the details
+ concerning its effect upon the O32 ABI in userland are still being
+ worked on. In order to avoid userland becoming dependant upon current
+ behaviour before the details have been finalised, this option should
+ be considered experimental and only enabled by those working upon
+ said details.

+ If unsure, say N.
