CONFIG_FLOAT

This option allows tasks and fibers to use the floating point registers. By default, only a single task or fiber may use the registers, and only the x87 FPU/MMX registers may be used.

Disabling this option means that any task or fiber that uses a floating point register will get a fatal exception.
