+ The <code>-mfpu</code> option now takes a new option setting of
+ <code>-mfpu=auto</code>. When set to this the floating-point and SIMD
+ settings are derived from the settings of the <code>-mcpu</code>
+ or <code>-march</code> options. The internal CPU configurations have been
+ updated with information about the permitted floating-point configurations
+ supported. See the user guide for further information about the extended
+ option syntax for controlling architectural extensions via the
+ <code>-march</code> option. <code>-mfpu=auto</code> is now the default
+ setting unless the compiler has been configured with an explicit
+ <code>--with-fpu</code> option.
