&os; has been updated to allow it to use the VFP variant of the + ARM EABI ABI. The VFP unit is the ARM hardware to perform + floating-point operations. This changes the ABI to improve the + performance of code that uses floating-point operations. By + default, &os; already uses the ARM EABI on all releases from + 10.0.

+ +

This is important for users of &os;/arm with an ARMv6 or ARMv7 + SoC and who use code that makes use of floating-point + operations. It removes the need for the slow software + floating-point support in libc. This is mostly + compatible with the existing ABI, with the exception of how + floating-point values are passed into functions. Because no + floating-point values are passed to the kernel, the + armv6 and armv6hf kernels will work with + either userland.

+ +

As part of this, some support functions have been updated to + use the VFP unit when available. It is intended the existing + armv6 target architecture will be kept for cases where + the SoC lacks a VFP unit, or existing binaries that are + incompatible with the new ABI.
