20 Indefinite or limited library level objects are now returned on
22 * exp_ch7.adb (Build_Finalization_Master): Add formal
23 parameter For_Lib_Level. Add context specific insertion for a
24 finalization master created for an access result type related
25 to a build-in-place function call used to initialize a library
27 * exp_ch7.ads (Build_Finalization_Master): Add formal parameter
28 For_Lib_Level. Update the comment on usage.
29 * sem_util.adb (Mark_Coextensions): Code cleanup.

43 2015-10-16 Bob Duff <duff@adacore.com>
45 * a-convec.adb ("="): Previous version depended
46 on "=" composing, but that doesn't quite work -- we want the "="
47 operator passed in to the generic. So we need a loop after all.
49 2015-10-16 Yannick Moy <moy@adacore.com>
51 * sem_util.adb (Is_Object_Reference): Attribute 'Loop_Entry produces
53 * sem_ch6.adb: Minor fix in comment.
55 2015-10-16 Bob Duff <duff@adacore.com>
57 * a-contai.ads: Add two check names: Container_Checks and
58 Tampering_Check. Move the tampering check machinery from
59 Ada.Containers.Vectors to Ada.Containers. Later we can share it
60 with other containers.
61 Disable the tampering machinery in the presence of
62 Suppress(Tampering_Check).
63 Simplify the implementation of tampering checks. E.g. use RAII
64 to make incrementing/decrementing of the counts more concise.
65 * a-contai.adb: New package body, implementing the above.
66 * a-convec.ads, a-convec.adb: Use tampering check machinery
68 Disable all checking code when checks are suppressed.
69 Simplify many of the operations. Implement "&" in terms of Append,
70 rather than "by hand".
71 Remove: function "=" (L, R : Elements_Array) return Boolean is
72 abstract; so we can call the predefined "=" on Elements_Array.
73 For "=" on Vectors: Previously, we returned True immediately if
74 Left'Address = Right'Address. That seems like a non-optimization
75 ("if X = X" is unusual), so removed that. Simplify by using
76 slice comparison ("=" on Element_Array will automatically call
77 "=" on the components, even if user defined).

131 2015-10-16 Bob Duff <duff@adacore.com>
133 * bindgen: Move pragmas Warnings earlier, otherwise
134 we can get warnings on with_clauses.

945 and is also the initial expression in an object declaration.

958 in a derived type if inherited through an ancestor that has a
959 partial view of the original type holding the component, if the
960 full view of that original type is in scope.
961 * sem_util.ads (Get_Body_From_Stub): Works for all kinds of stubs.
963 2015-05-28 Bob Duff <duff@adacore.com>
965 * sem_util.adb (Requires_Transient_Scope): For definite untagged
966 subtypes, we should never have to use the secondary stack. This moves
967 toward that goal. But there are still cases that don't work.
968 Here, we move the check for Is_Definite first, but add a
969 special-purpose check for Has_Discrim_Dep_Array.
971 2015-05-28 Bob Duff <duff@adacore.com>
973 * sem_util.adb (Requires_Transient_Scope): Avoid returning
974 function results on the secondary stack in so many cases.
976 2015-05-28 Ed Schonberg <schonberg@adacore.com>

979 if type of expression is the partial view of the expected type.
981 2015-05-28 Ed Schonberg <schonberg@adacore.com>
983 * sem_res.adb (Resolve_Actuals): a) The replacement of formal
984 names in named associations only needs to be done within an
985 instance, on a call to a primitive of a formal derived type,
986 where the actual subprogram may have different formal names than
987 those of the primitive operation of the formal type.
988 b) Defaulted parameters must be taken into account when obtaining
989 the names of the formals of the actual subprogram being called.
991 2015-05-28 Robert Dewar <dewar@adacore.com>
993 * sem_ch13.adb, sem_disp.ads: Minor reformatting.

999 underlying full view as well, for proper gdb display.
1001 2015-05-28 Bob Duff <duff@adacore.com>
1003 * exp_tss.ads: Minor comment fix.
1004 * exp_ch3.adb (Build_Array_Init_Proc, Build_Record_Init_Proc):
1005 Inline init_procs when the type has controlled parts. Remove
1006 obsolete comments about those init_procs -- init_procs for
1007 such types are no longer complex. A typical init_proc just
1008 initializes the 'Tag field, and calls the parent init_proc
1009 (e.g. for Limited_Controlled), which calls the grandparent
1010 (for Root_Controlled), which does nothing. This all boils down
1011 to one instruction when inlined.
1012 * exp_ch7.adb (Create_Finalizer): Inline the finalizer.
1014 2015-05-28 Ed Schonberg <schonberg@adacore.com>
1016 * sem_ch4.adb (Analyze_Selected_Component): If the type to use
1017 is a derived type and is a generic actual, the selected component
1018 appears within an instance body, and the check over the type
1019 has failed, examine ancestor types for the desired component.

1062 condition/pragmas SCOs associations into a temporary table before
1063 moving them to the SCO_Raw_Hash_Table so that we can back them

1072 2015-05-27 Ed Schonberg <schonberg@adacore.com>
1074 * exp_ch5.adb (Expand_N_Case_Statement): If the expression in
1075 the case statement is a compile-time known value, we look for a
1076 corresponding alternative to optimize the case statement into a
1077 single case. If the type has a static predicate and the expression
1078 does not satisfy the predicate, there is no legal alternative and
1079 this optimization is not applicable. Excecution is erroneous,
1080 or else if assertions are enabled, an exception will be raised

1100 * sem_elab.adb (Check_A_Call): In the case where we're
1101 calling something in an instance of a generic package that is
1102 within this same unit (as the call), make sure we treat it
1103 as a call to an entity within the same unit. That is, call
1104 Check_Internal_Call, rather than putting "Elaborate_All(X)"
1105 on X, which would necessarily result in an elaboration cycle in
1106 static-elaboration mode.

1209 body. Remove useless freeze nodes for incomplete actuals to
1210 prevent multiple generation of internal operations.
1211 (Instantiate_Package_Body): Set sloc of body appropriately when
1212 there are incomplete actuals and the instance body is placed in
1213 the body of the enclosing unit.

1239 of original expression in ASIS mode: does not solve the ASIS

1666 checks, that function call, though it is labelled Analyzed to

1785 which may be in the private part and not directly visible,

1998 * sem_res.adb (Resolve_Actuals): If the call is to an overridden
1999 operation, replace the names of the actuals in named associations
2000 with the names of the actuals of the subprogram that is eventually
2001 executed. The names of the formals and the defaults can differ
2002 between the two operations when they are operations of a formal

2062 Instead of doing literally what the RM calls for, we do something
2063 equivalent that avoids expensive operations inside the loop. If the
2064 container package has appropriate Next, Pseudo_Reference,
2065 Element_Access, Get_Element_Access declarations, we invoke the
2067 * snames.ads-tmpl: Note speed improvement.

2176 (Install_Body): In the presence of actuals that incomplete types

2178 the declaration because full views have not been seen yet. Any
2179 use of the non-limited views in the instance body requires
2180 the presence of a regular with_clause in the enclosing unit,
2181 and will fail if this with_clause is missing. We place the
2182 instance body at the beginning of the enclosing body, which is
2183 the unit being compiled, and ensure that freeze nodes for the
2184 full views of the incomplete types appear before the instance.

2972 expression when the object declaration carries aspects Address
2974 * freeze.adb (Freeze_Object_Declaration): New subsidiary procedure
2975 to Freeze_Entity. In addition to the previous processing steps
2976 at the freeze point of an object, this procedure also handles
2977 aggregates in object declarations, when the declaration carries

2979 object be attached to its freeze actions.

2995 that predicate functions are constructed.
2997 2015-05-12 Ed Schonberg <schonberg@adacore.com>
2999 * sem_ch6.adb (Process_Formals): If a tagged formal is an
3000 incomplete class-wide type, the subprogram must have a delayed
3001 freeze even though the opertation is not a primitive of the
3002 type. THis ensures that the backend can recover the full view
3003 when elaborating the subprogram declaration.

3030 * sem_ch3.adb (Analyze_Component_Declaration): If the component is
3031 an unconstrained synchronized type with discriminants, create a
3032 constrained default subtype for it, so that the enclosing record
3033 can be given the proper size.
3034 * sem_util.adb (Build_Default_Subtype): If the subtype is created
3035 for a record discriminant, do not analyze the declarztion at
3036 once because it is added to the freezing actions of the enclosing
