2017-04-25  Tristan Gingold  <gingold@adacore.com>

	* s-mmap.ads (Data): Add pragma Inline.

2017-04-25  Hristian Kirtchev  <kirtchev@adacore.com>

	* checks.adb (Insert_Valid_Check): Do not use
	a renaming to alias a volatile name because this will lead to
	multiple evaluations of the volatile name. Use a constant to
	capture the value instead.

2017-04-25  Doug Rupp  <rupp@adacore.com>

	* init.c [VxWorks Section]: Disable sigtramp for ppc64-vx7.

2017-04-25  Ed Schonberg  <schonberg@adacore.com>

	* exp_util.adb, exp_util.ads (Build_Class_Wide_Expression):
	Add out parameter to indicate to caller that a wrapper must
	be constructed for an inherited primitive whose inherited
	pre/postcondition has called to overridden primitives.
	* freeze.adb (Check_Inherited_Conditions): Build wrapper body
	for inherited primitive that requires it.
	* sem_disp.adb (Check_Dispatching_Operation): Such wrappers are
	legal primitive operations and belong to the list of bodies
	generated after the freeze point of a type.
	* sem_prag.adb (Build_Pragma_Check_Equivalent): Use new signature
	of Build_Class_Wide_Expression.
	* sem_util.adb, sem_util.ads (Build_Overriding_Spec): New procedure
	to construct the specification of the wrapper subprogram created
	for an inherited operation.
