2016-11-06  Andre Vehreschild  <vehre@gcc.gnu.org>

	* expr.c (is_non_empty_structure_constructor): New function to detect
	non-empty structure constructor.
	(gfc_has_default_initializer): Analyse initializers.
	* resolve.c (cond_init): Removed.
	(resolve_allocate_expr): Removed dead code.  Moved invariant code out
	of the loop over all objects to allocate.
	(resolve_allocate_deallocate): Added the invariant code remove from
	resolve_allocate_expr.
	* trans-array.c (gfc_array_allocate): Removed nullify of structure
	components in favour of doing this in gfc_trans_allocate for both
	scalars and arrays in the same place.
	* trans-expr.c (gfc_trans_init_assign): Always using _vptr->copy for
	class objects.
	* trans-stmt.c (allocate_get_initializer): Get the initializer
	expression for object allocated.
	(gfc_trans_allocate): Nullify a derived type only, when no SOURCE=
	or MOLD= is present preventing duplicate work.  Moved the creation
	of the init-expression here to prevent code for conditions that
	can not occur on freshly allocated object, like checking for the need
	to free allocatable components.

    libgo: avoid confusion in upcase_fields in mksysinfo.sh
    
    The mksysinfo.sh script could get confused when there were multiple
    types starting with the same name.  I believe this is the underlying
    cause of GCC PR 78172.
    
    Also redirect a grep to /dev/null to avoid extraneous messages during
    the build.

Adjust some comments, add some explicit fall through comments or explicit
returns where necessary to not get implicit-fallthrough warnings.

All fall throughs were deliberate. In one case I added an explicit return
false for clarity instead of falling through a default case (that also
would return false).

libiberty/ChangeLog:

       * cplus-dem.c (demangle_signature): Move fall through comment.
       (demangle_fund_type): Add fall through comment between 'G' and 'I'.
       * hashtab.c (iterative_hash): Add fall through comments.
       * regex.c (regex_compile): Add Fall through comment after '+'/'?'.
       (byte_re_match_2_internal): Add Fall through comment after jump_n.
       Change "Note fall through" to "Fall through".
       (common_op_match_null_string_p): Return false after set_number_at
       instead of fall through.
