Hi,

The comment describing ARM register allocation in arm.h contains 3 keys:
S, F and *. The legend only explains S and *, this patch remedies that.

ChangeLog entry is as follows:

*** gcc/ChangeLog ***

2017-05-24  Thomas Preud'homme  <thomas.preudhomme@arm.com>

	* config/arm/arm.h: explain F symbol found in description of ARM
	register allocation in its legend.

Is this ok for trunk?

Best regards,

Thomas
