[Bug c/20533] New: documentation: attribute 'used', applied to a variable

[gary at intrepid dot com]

See related discussion in Bug #20319, and at
http://gcc.gnu.org/ml/gcc/2005-03/msg00450.html

The "used" attribute is described only under "function attributes"
and not under "variable attributes" in the documentation:

used
This attribute, attached to a function, means that code must be emitted for 
the function even if it appears that the function is not referenced. This is 
useful, for example, when the function is referenced only in inline assembly. 

(see: http://gcc.gnu.org/onlinedocs/gcc-3.4.3/gcc/Function-
Attributes.html#Function-Attributes)

It would be helpful if the documentation were updated to describe the
behavior of the `used' attribute when apllied to variables.
