	* sem_util.adb (Contains_Refined_State): Remove.

2017-12-05  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch13.adb (Analyze_Aspect_Specifications, case Predicate): A
	predicate cannot apply to a formal type.

2017-12-05  Arnaud Charlet  <charlet@adacore.com>

	* exp_unst.ads: Fix typos.

2017-12-05  Jerome Lambourg  <lambourg@adacore.com>

	* libgnarl/s-taprop__qnx.adb: Better detect priority ceiling bug in
	QNX.  At startup, the first mutex created has a non-zero ceiling
	priority whatever its actual policy. This makes some tests fail
	(c940013 for example).

2017-12-05  Bob Duff  <duff@adacore.com>

	* exp_ch11.adb (Expand_N_Handled_Sequence_Of_Statements): Call
	Expand_Cleanup_Actions for N_Extended_Return_Statement.
	* exp_ch7.adb (Expand_Cleanup_Actions): Handle
	N_Extended_Return_Statement by transforming the statements into a
	block, and (indirectly) calling Expand_Cleanup_Actions on the block.
	It's too hard for Expand_Cleanup_Actions to operate directly on the
	N_Extended_Return_Statement, because it has a different structure than
	the other node kinds that Expand_Cleanup_Actions.
	* exp_util.adb (Requires_Cleanup_Actions): Add support for
	N_Extended_Return_Statement.  Change "when others => return False;" to
	"when others => raise ...;" so it's clear what nodes this function
	handles.  Use named notation where appropriate.
	* exp_util.ads: Mark incorrect comment with ???.

2017-12-05  Javier Miranda  <miranda@adacore.com>

	* exp_ch9.adb (Install_Private_Data_Declarations): Add missing
	Debug_Info_Needed decoration of internally generated discriminal
	renaming declaration.

2017-12-05  Arnaud Charlet  <charlet@adacore.com>

	* exp_unst.adb (Unnest_Subprogram): Add handling of 'Access on
	nested subprograms.

2017-12-05  Sergey Rybin  <rybin@adacore.com>

	* doc/gnat_ugn/gnat_utility_programs.rst: Add description of '--ignore'
	option for gnatmetric, gnatpp, gnat2xml, and gnattest.

2017-12-05  Piotr Trojanek  <trojanek@adacore.com>

	* sem_util.adb (Contains_Refined_State): Remove.

2017-12-05  Piotr Trojanek  <trojanek@adacore.com>

	* rtsfind.ads: Add new enumeration literals: RE_Clock_Time (for
	Ada.Real_Time.Clock_Time) and RO_CA_Clock_Time (for
	Ada.Calendar.Clock_Time).

2017-12-05  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch4.adb (Is_Private_Overriding): If the candidate private
	subprogram is overloaded, scan the list of homonyms in the same
	scope, to find the inherited operation that may be overridden
	by the candidate.
	* exp_ch11.adb, exp_ch7.adb: Minor reformatting.

2017-12-05  Bob Duff  <duff@adacore.com>

	* exp_ch6.adb (Expand_N_Extended_Return_Statement): If the
	Init_Assignment is rewritten, we need to set Assignment_OK on the new
	node.  Otherwise, we will get spurious errors when initializing via
	assignment statement.
