71 * sem_ch13.adb (Analyze_Aspects_At_Freeze_Point): Do not process
72 aspects for the anonymous base type constructed for a derived
73 scalar type, because they will be set when the first subtype

139 to Freeze_Entity. In addition to the previous processing steps
140 at the freeze point of an object, this procedure also handles
141 aggregates in object declarations, when the declaration carries

159 that predicate functions are constructed.
161 2015-05-12 Ed Schonberg <schonberg@adacore.com>
163 * sem_ch6.adb (Process_Formals): If a tagged formal is an
164 incomplete class-wide type, the subprogram must have a delayed
165 freeze even though the opertation is not a primitive of the
166 type. THis ensures that the backend can recover the full view
167 when elaborating the subprogram declaration.
169 2015-05-12 Ed Schonberg <schonberg@adacore.com>
171 * exp_util.adb (Get_Current_Value_Condition): Nothing to be

195 an unconstrained synchronized type with discriminants, create a
196 constrained default subtype for it, so that the enclosing record
197 can be given the proper size.
198 * sem_util.adb (Build_Default_Subtype): If the subtype is created
199 for a record discriminant, do not analyze the declarztion at
200 once because it is added to the freezing actions of the enclosing
201 record type.
203 2015-05-12 Robert Dewar <dewar@adacore.com>

881 call to String'Input, returning a dynamically sized value on the
882 secondary stack) will be expanded outside of proper secondary
883 stack mark/release operations, and will thus cause a secondary
884 stack leak.

1021 is a generic subprogram. The same pragmas are no longer
1022 forcefully fully analyzed when the context is a subprogram
1023 that acts as a compilation unit. Pragmas Abstract_State,
1024 Initial_Condition, Initializes and Refined_State have been clean
1025 up. Pragmas Post, Post_Class, Postcondition, Pre, Pre_Class
1026 and Precondition now use the same routine for analysis. Pragma
1027 Refined_Post does not need to check the use of 'Result or
1028 the lack of a post-state in its expression. Reimplement the
1029 analysis of pragma Test_Case.

2595 * freeze.adb (Build_Renamed_Body): If the return type of the
2596 declaration that is being completed is a limited view and the

2810 ttypes values and the GNAT tree nodes for the standard floating
2811 point types.
2812 * set_targ.adb (Long_Double_Index): The index at which "long
2813 double" gets registered in the FPT_Mode_Table. This is useful to
2814 know whether we have a "long double" available at all and get at
2815 it's characteristics without having to search the FPT_Mode_Table
2816 when we need to decide which C type should be used as the

2824 suitable as a basis to construct the standard Ada floating point
2825 type identified by the input T parameter.
2826 (elaboration code): Register_Back_End_Types unconditionally,
2827 so C_Type_For can operate regardless of -gnateT. Do it
2828 early so we can query it for the floating point sizes, via
2829 FPT_Mode_Index_For. Initialize Float_Size, Double_Size and
2830 Long_Double_Size from the FPT_Mode_Table, as cstand will do.
2831 * cstand.adb (Create_Float_Types): Use C_Type_For to determine
2832 which C type should be used as the basis for the construction
2833 of the Standard Ada floating point types.

2852 build function and operator wrappers after the actual subprogram
2853 has been resolved, and replace the standard renaming declaration
2854 with the declaration of wrapper.
2855 * sem_ch12.ads (Build_Function_Wrapper, Build_Operator_Wraooer):
2856 make public for use elsewhere.
2857 * sem_ch12.adb (Build_Function_Wrapper, Build_Operator_Wraooer):
2858 rewrite, now that actual is fully resolved when wrapper is
2859 constructed.
2861 2015-01-06 Javier Miranda <miranda@adacore.com>

2883 others choice that covers multiple components, analyze each
2884 copy with the type of the component even in compile-only mode,
2885 to detect potential accessibility errors.
2887 2015-01-06 Hristian Kirtchev <kirtchev@adacore.com>

2900 last_entity may have been assigned already.
2902 2015-01-06 Ed Schonberg <schonberg@adacore.com>
2904 * sem_ch4.adb (Analyze_One_Call): If formal has an incomplete
2905 type and actual has the corresponding full view, there is no

2990 2015-01-06 Javier Miranda <miranda@adacore.com>
2992 * exp_disp.adb (Expand_Interface_Conversion): No displacement
2993 of the pointer to the object needed when the type of the operand
2994 is not an interface type and the interface is one of its parent
2995 types (since they share the primary dispatch table).
2997 2015-01-06 Vincent Celier <celier@adacore.com>
2999 * prj-env.adb: Minor comment update.
3001 2015-01-06 Javier Miranda <miranda@adacore.com>
3003 * sem_res.adb (Valid_Conversion): Restrict the checks on anonymous
3004 access types whose target type is an interface type to operands
3005 that are access types; required to report an error when the
3006 operand is not an access type.
3008 2015-01-06 Bob Duff <duff@adacore.com>
3010 * a-cfinve.adb (Copy): Set the discriminant to the Length when
3011 Capacity = 0.
3012 * a-cofove.ads (Capacity): Add a postcondition.
3013 * a-cfinve.ads (Capacity): Add a postcondition.

3019 2015-01-06 Ed Schonberg <schonberg@adacore.com>

3036 * prj-env.adb (Initialize_Default_Project_Path): When both
3037 Target_Name and Runtime_Name are not empty string, add to the

3047 rewritten as a null statement.
3048 * sem_prag.adb (Analyze_Pragma): Insert a brand new Check_Policy
3049 pragma using Insert_Before rather than Insert_Action. This
3050 takes care of the configuration pragma case where Insert_Action
3051 would fail.
3053 2015-01-06 Bob Duff <duff@adacore.com>
3055 * a-coboho.ads (Element_Access): Add "pragma
3056 No_Strict_Aliasing (Element_Access);". This is needed because
