27 2015-05-27 Pierre-Marie de Rodat <derodat@adacore.com>
29 * par_sco.adb (Process_Decision): Store sloc to
30 condition/pragmas SCOs associations into a temporary table before
31 moving them to the SCO_Raw_Hash_Table so that we can back them
32 out just like we do for SCO entries that are simple decisions
33 in an expression context.
35 2015-05-27 Ed Schonberg <schonberg@adacore.com>
37 * sem_ch6.adb (Process_Formals): A non-private formal type that
38 is a limited view does not have a list of private dependents.
40 2015-05-27 Ed Schonberg <schonberg@adacore.com>
42 * exp_ch5.adb (Expand_N_Case_Statement): If the expression in
43 the case statement is a compile-time known value, we look for a
44 corresponding alternative to optimize the case statement into a
45 single case. If the type has a static predicate and the expression
46 does not satisfy the predicate, there is no legal alternative and
47 this optimization is not applicable. Excecution is erroneous,
48 or else if assertions are enabled, an exception will be raised
49 earlier, at the point the expression is elaborated.

66 2015-05-26 Bob Duff <duff@adacore.com>
68 * sem_elab.adb (Check_A_Call): In the case where we're
69 calling something in an instance of a generic package that is
70 within this same unit (as the call), make sure we treat it
71 as a call to an entity within the same unit. That is, call
72 Check_Internal_Call, rather than putting "Elaborate_All(X)"
73 on X, which would necessarily result in an elaboration cycle in
74 static-elaboration mode.
76 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
78 * freeze.ads (Is_Atomic_VFA_Aggregate): Adjust profile.

96 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
98 * gcc-interface/trans.c (gnat_to_gnu) <N_Object_Declaration>: Really
99 force evaluation of the expression, if any, when the object has its
100 elaboration delayed. Do not create a variable at global level.
102 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
104 * gcc-interface/trans.c (Attribute_to_gnu) <Attr_Machine>: Do not apply
105 extra-precision trick to literals. Build SAVE_EXPR manually.
107 * gcc-interface/misc.c (enumerate_modes): Add bypass for x86/x86-64.

122 and simplify associated code. Set const_flag to true consistently in
123 conjunction with used_by_ref.
124 * gcc-interface/trans.c (Identifier_to_gnu): Always replace renaming
125 pointers by renamed objects.
126 (outer_atomic_access_required_p): Deal with renamings.
127 (Compilation_Unit_to_gnu): Do not call
128 invalidate_global_nonconstant_renamings.

146 * gcc-interface/gigi.h (gnat_stabilize_reference): Adjust prototype.
147 * gcc-interface/decl.c (gnat_to_gnu_entity): Do not rely on const_flag
148 to detect constant renamings. Be prepared for specific pattern of
149 renamed object based on function calls. Create a constant object
150 for the renaming of a NULL_EXPR or of a CONSTRUCTOR. Adjust calls
151 to gnat_stabilize_reference and tidy up. Remove redundant tests.

177 body. Remove useless freeze nodes for incomplete actuals to
178 prevent multiple generation of internal operations.

181 the body of the enclosing unit.
182 * errout.ads: Consistent punctuation, better alignment and trivial
184 * err_vars.ads: Fix typo.
186 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
188 * sem_ch8.adb (Analyze_Object_Renaming): Lift restriction on
189 components of Volatile_Full_Access objects.

202 (Write_Field19_Name): ...here.
204 2015-05-26 Ed Schonberg <schonberg@adacore.com>
206 * sem_ch13.adb: sem_ch13.adb (Add_Predicates): Undo analysis
207 of original expression in ASIS mode: does not solve the ASIS
208 problem of a usable type information, and crashes the back-end
209 when performing type annotations.

221 exp_ch3.adb: Minor reformatting.
223 2015-05-26 Bob Duff <duff@adacore.com>
225 * treepr.adb: Minor improvement to debugging routines (pp, pn)
226 robustness. Rearrange the code so passing a nonexistent Node_Id
227 prints "No such node" rather than crashing, and causing gdb to
228 generate confusing messages.
230 2015-05-26 Gary Dismukes <dismukes@adacore.com>

1030 Instead of doing literally what the RM calls for, we do something
1031 equivalent that avoids expensive operations inside the loop. If the
1032 container package has appropriate Next, Pseudo_Reference,
1033 Element_Access, Get_Element_Access declarations, we invoke the
1035 * snames.ads-tmpl: Note speed improvement.

1144 (Install_Body): In the presence of actuals that incomplete types
1145 from a limited view, the instance body cannot be placed after
1146 the declaration because full views have not been seen yet. Any
1147 use of the non-limited views in the instance body requires
1148 the presence of a regular with_clause in the enclosing unit,
1149 and will fail if this with_clause is missing. We place the
1150 instance body at the beginning of the enclosing body, which is
1151 the unit being compiled, and ensure that freeze nodes for the
1152 full views of the incomplete types appear before the instance.

2529 invariants will be propagated to the invariant procedure of
2530 types covering the interface.

2678 2015-03-02 Thomas Quinot <quinot@adacore.com>
2680 * exp_attr.adb (Expand_N_Attribute_Reference, case Input): When
2681 expanding a 'Input attribute reference for a class-wide type,
2682 do not generate a separate object declaration for the controlling
2683 tag dummy object; instead, generate the expression inline in the
2684 dispatching call. Otherwise, the declaration (which involves a
2685 call to String'Input, returning a dynamically sized value on the
2686 secondary stack) will be expanded outside of proper secondary
2687 stack mark/release operations, and will thus cause a secondary

2892 * sem_ch8.adb (Available_Subtype): Optimization in
2893 Find_Selected_Component: when safe, use existing subtype of
2894 array component, possibly discriminant-dependent, rather than
2895 creating new subtype declaration for it. In this fashion different
2896 occurrences of the component have the same subtype, rather than
2897 just equivalent ones. Simplifies value tracing in GNATProve.

4614 ttypes values and the GNAT tree nodes for the standard floating
4616 * set_targ.adb (Long_Double_Index): The index at which "long
