Eric Botcazou b748c3d1b7 [Ada] Further improve the expansion of array aggregates
gcc/ada/

	* exp_aggr.adb
	(Convert_To_Positional): Add Dims local variable
	and pass it in calls to Is_Flat and Flatten.
	(Check_Static_Components): Pass Dims in call to
	Is_Static_Element.
	(Nonflattenable_Next_Aggr): New predicate.
	(Flatten): Add Dims parameter and Expr local variable.  Call
	Nonflattenable_Next_Aggr in a couple of places.  In the case
	when an Others choice is present, check that the element is
	either static or a nested aggregate that can be flattened,
	before disregarding the replication limit for elaboration
	purposes.  Check that a nested array is flattenable in the case
	of a multidimensional array in any position.  Remove redundant
	check in the Others case and pass Dims in call to
	Is_Static_Element.  Use Expr variable.
	(Is_Flat): Change type of Dims parameter from Int to Nat.
	(Is_Static_Element): Add Dims parameter.  Replace tests on
	literals with call to Compile_Time_Known_Value.  If everything
	else failed and the dimension is 1, preanalyze the expression
	before calling again Compile_Time_Known_Value on it.  Return
	true for null.
	(Late_Expansion): Do not expand further if the assignment to the
	target can be done directly by the back end.

This directory contains the GNU Compiler Collection (GCC).

The GNU Compiler Collection is free software.  See the files whose
names start with COPYING for copying permission.  The manuals, and
some of the runtime libraries, are under different terms; see the
individual source files for details.

The directory INSTALL contains copies of the installation information
as HTML and plain text.  The source of this information is
gcc/doc/install.texi.  The installation information includes details
of what is included in the GCC sources and what files GCC installs.

See the file gcc/doc/gcc.texi (together with other files that it
includes) for usage and porting information.  An online readable
version of the manual is in the files gcc/doc/gcc.info*.

See http://gcc.gnu.org/bugs/ for how to report bugs usefully.

Copyright years on GCC source files may be listed using range
notation, e.g., 1987-2012, indicating that every year in the range,
inclusive, is a copyrightable year that could otherwise be listed
individually.
