	* sem_ch10.adb: Minor reformatting.

2014-08-01  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch6.adb (Same_Generic_Actual): Make function symmetric,
	because either type may be a subtype of the other.

	* makeusg.adb: Add documentation for debug switch -dn.

	* sem_dim.adb (Process_Minus, Process_Divide): Label dimension
	expression with standard operator and type, for pretty-printing
	use, when in ASIS_Mode. When generating code dimensional analysis
	is not involved and dimension expressions are handled statically,
	and other operators are resolved in the usual way.

	* sem_ch3.adb (Build_Derived_Record_Type): Remove setting of
	Parent_Subtype in ASIS mode, leads to several failures.
	* sem_ch4.adb (Analyze_Selected_Component): In an instance,
	if the prefix is a type extension, check whether component is
	declared in the parent type, possibly in a parent unit. Needed
	in ASIS mode when Parent_Subtype is not set.
