Janne Grunau	74cc901905	float_dsp: fix errors in documentation	11 years ago
Janne Grunau	c708b54033	timer: use mach_absolute_time as high resolution clock on darwin Not guaranteed to be in nanosecond resolution. On iOS 7 the duration of one tick is 125/3 ns which is still more than an order of magnitude better then microseconds. Replace decicycles with the neutral UNITS. Decicycles is strange but tenths of a nanosecond and unspecific "deci"-ticks for mach_absolute_time is just silly.	11 years ago

James Almer	3f3d748cab	x86: Move XOP emulation to x86util We need the emulation to support the cases where the first argument is the same as the fourth.
