argument.

2011-08-02 Hristian Kirtchev <kirtchev@adacore.com>
* exp_ch5.adb (Expand_Iterator_Loop): Code cleanup and reorganization.
Set the associated loop as the related expression of internally
generated cursors.
* exp_ch7.adb (Is_Container_Cursor): New routine.
(Wrap_Transient_Declaration): Supress the finalization of the list
controller when the declaration denotes a container cursor.
2011-08-02 Yannick Moy <moy@adacore.com>
* opt.ads (SPARK_Mode): update comment, SPARK_Mode only set through
command line now.
* par-ch3.adb (P_Delta_Constraint): remove check in SPARK mode that the
expression is a simple expression. This check cannot be performed in
the semantics, so just drop it.
(P_Index_Or_Discriminant_Constraint): move check that the index or
discriminant is a subtype mark to Analyze_Subtype_Declaration in the
semantics. Other cases were previously checked in the semantics.
* par-ch4.adb (P_Name): move checks that a selector name is not
character literal or an operator symbol to Find_Selected_Component in
the semantics
* par-ch5.adb (Parse_Decls_Begin_End): move check that basic
declarations are not placed after later declarations in a separate
procedure in Sem_Util (possibly not the best choice?), to be used both
during parsing, for Ada 83 mode, and during semantic analysis, for
SPARK mode.

to Process_End_Label in the semantics
* par-prag.adb (Process_Restrictions_Or_Restriction_Warnings): remove
the special case for SPARK restriction
* par.adb: use and with Sem_Util, for use in Parse_Decls_Begin_End
* restrict.adb, restrict.ads (Check_Formal_Restriction): add a
parameter Force to issue the error message even on internal node (used
for generated end label). Call Check_Restriction to check when an error
must be issued. In SPARK mode, issue an error message even if the
restriction is not set.
(Check_Restriction): new procedure with an additional out parameter to
inform the caller that a message has been issued
* sem_aggr.adb: Minor modification of message
* sem_attr.adb (Analyze_Attribute): call Check_Formal_Restriction
instead of issuing an error message directly
* sem_ch3.adb (Analyze_Declarations): move here the check that basic
declarations are not placed after later declarations, by calling
Check_Later_Vs_Basic_Declarations
(Analyze_Subtype_Declaration): move here the check that an index or
discriminant constraint must be a subtype mark. Change the check that
a subtype of String must start at one so that it works on subtype marks.
* sem_ch4.adb (Analyze_Call): move here the check that a named
association cannot follow a positional one in a call
* sem_ch5.adb (Check_Unreachable_Code): call Check_Formal_Restriction
instead of issuing an error message directly
* sem_ch8.adb (Find_Selected_Component): move here the check that a
selector name is not a character literal or an operator symbol. Move
here the check that the prefix of an expanded name cannot be a
subprogram or a loop statement.
* sem_util.adb, sem_util.ads (Check_Later_Vs_Basic_Declarations): new
procedure called from parsing and semantics to check that basic
declarations are not placed after later declarations
(Process_End_Label): move here the check that end label is not missing
2011-08-02 Arnaud Charlet <charlet@adacore.com>
* sem_ch13.adb (Analyze_Enumeration_Representation_Clause): Ignore enum
representation clause in codepeer mode, since it confuses CodePeer and

2011-08-02 Ed Schonberg <schonberg@adacore.com>

optimization). For other nodes, do not check source_unit if the node
comes from Standard.

on an Ada2012 iterator, insert them ahead of the rewritten loop.

an undocumented use of Node21 in E_Access_Subprogram_Type entities

this attribute.
