3 * gcc-interface/trans.c (elaborate_all_entities): Do not elaborate an
4 incomplete type coming from a limited_with and whose non-limited view
5 comes from the main unit.
7 2015-05-27 Eric Botcazou <ebotcazou@adacore.com>
9 * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Variable>: Move down
10 code applying atomic checks to the object.
12 2015-05-27 Robert Dewar <dewar@adacore.com>

30 * adaint.c (__gnat_tmp_name) [vxworks]: Robustify and use for rtp as
33 2015-05-27 Pierre-Marie de Rodat <derodat@adacore.com>
35 * par_sco.adb (Process_Decision): Store sloc to
36 condition/pragmas SCOs associations into a temporary table before
37 moving them to the SCO_Raw_Hash_Table so that we can back them
38 out just like we do for SCO entries that are simple decisions
39 in an expression context.
41 2015-05-27 Ed Schonberg <schonberg@adacore.com>
43 * sem_ch6.adb (Process_Formals): A non-private formal type that
44 is a limited view does not have a list of private dependents.
46 2015-05-27 Ed Schonberg <schonberg@adacore.com>
48 * exp_ch5.adb (Expand_N_Case_Statement): If the expression in
49 the case statement is a compile-time known value, we look for a
50 corresponding alternative to optimize the case statement into a
51 single case. If the type has a static predicate and the expression
52 does not satisfy the predicate, there is no legal alternative and
53 this optimization is not applicable. Excecution is erroneous,
54 or else if assertions are enabled, an exception will be raised
55 earlier, at the point the expression is elaborated.

72 2015-05-26 Bob Duff <duff@adacore.com>
74 * sem_elab.adb (Check_A_Call): In the case where we're
75 calling something in an instance of a generic package that is
76 within this same unit (as the call), make sure we treat it
77 as a call to an entity within the same unit. That is, call
78 Check_Internal_Call, rather than putting "Elaborate_All(X)"
79 on X, which would necessarily result in an elaboration cycle in
80 static-elaboration mode.
82 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
84 * freeze.ads (Is_Atomic_VFA_Aggregate): Adjust profile.
85 * freeze.adb (Is_Atomic_VFA_Aggregate): Change Entity

102 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
104 * gcc-interface/trans.c (gnat_to_gnu) <N_Object_Declaration>: Really
105 force evaluation of the expression, if any, when the object has its
106 elaboration delayed. Do not create a variable at global level.
108 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
110 * gcc-interface/trans.c (Attribute_to_gnu) <Attr_Machine>: Do not apply
111 extra-precision trick to literals. Build SAVE_EXPR manually.
113 * gcc-interface/misc.c (enumerate_modes): Add bypass for x86/x86-64.
115 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>

128 and simplify associated code. Set const_flag to true consistently in
129 conjunction with used_by_ref.
130 * gcc-interface/trans.c (Identifier_to_gnu): Always replace renaming
131 pointers by renamed objects.
132 (outer_atomic_access_required_p): Deal with renamings.
133 (Compilation_Unit_to_gnu): Do not call
134 invalidate_global_nonconstant_renamings.

152 * gcc-interface/gigi.h (gnat_stabilize_reference): Adjust prototype.
153 * gcc-interface/decl.c (gnat_to_gnu_entity): Do not rely on const_flag
154 to detect constant renamings. Be prepared for specific pattern of
155 renamed object based on function calls. Create a constant object
156 for the renaming of a NULL_EXPR or of a CONSTRUCTOR. Adjust calls
157 to gnat_stabilize_reference and tidy up. Remove redundant tests.
158 (elaborate_expression_1): Remove obsolete test and tidy up.

183 body. Remove useless freeze nodes for incomplete actuals to
184 prevent multiple generation of internal operations.
185 (Instantiate_Package_Body): Set sloc of body appropriately when
186 there are incomplete actuals and the instance body is placed in
187 the body of the enclosing unit.
188 * errout.ads: Consistent punctuation, better alignment and trivial
190 * err_vars.ads: Fix typo.
192 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
194 * sem_ch8.adb (Analyze_Object_Renaming): Lift restriction on
195 components of Volatile_Full_Access objects.

208 (Write_Field19_Name): ...here.
210 2015-05-26 Ed Schonberg <schonberg@adacore.com>
212 * sem_ch13.adb: sem_ch13.adb (Add_Predicates): Undo analysis
213 of original expression in ASIS mode: does not solve the ASIS
214 problem of a usable type information, and crashes the back-end
215 when performing type annotations.
217 2015-05-26 Robert Dewar <dewar@adacore.com>

227 exp_ch3.adb: Minor reformatting.
229 2015-05-26 Bob Duff <duff@adacore.com>
231 * treepr.adb: Minor improvement to debugging routines (pp, pn)
232 robustness. Rearrange the code so passing a nonexistent Node_Id
233 prints "No such node" rather than crashing, and causing gdb to
234 generate confusing messages.
236 2015-05-26 Gary Dismukes <dismukes@adacore.com>

436 to ensure proper visibility in parent units analyzed for inlining.
438 2015-05-26 Yannick Moy <moy@adacore.com>

473 sem_ch12.adb, sem_ch3.adb, sem_ch4.adb, sem_ch6.adb, sem_ch7.adb,
474 sem_util.adb: Change the sense of Is_Indefinite_Subtype to be
475 Is_Definite_Subtype. This is an improvement to readability (the double

1036 Instead of doing literally what the RM calls for, we do something
1037 equivalent that avoids expensive operations inside the loop. If the
1038 container package has appropriate Next, Pseudo_Reference,
1039 Element_Access, Get_Element_Access declarations, we invoke the

1150 (Install_Body): In the presence of actuals that incomplete types

1152 the declaration because full views have not been seen yet. Any
1153 use of the non-limited views in the instance body requires
1154 the presence of a regular with_clause in the enclosing unit,
1155 and will fail if this with_clause is missing. We place the
1156 instance body at the beginning of the enclosing body, which is
1157 the unit being compiled, and ensure that freeze nodes for the
1158 full views of the incomplete types appear before the instance.

2687 expanding a 'Input attribute reference for a class-wide type,
2688 do not generate a separate object declaration for the controlling
2689 tag dummy object; instead, generate the expression inline in the
2690 dispatching call. Otherwise, the declaration (which involves a
2691 call to String'Input, returning a dynamically sized value on the
2692 secondary stack) will be expanded outside of proper secondary
2693 stack mark/release operations, and will thus cause a secondary

4620 ttypes values and the GNAT tree nodes for the standard floating
4622 * set_targ.adb (Long_Double_Index): The index at which "long
4623 double" gets registered in the FPT_Mode_Table. This is useful to

4640 Long_Double_Size from the FPT_Mode_Table, as cstand will do.
4641 * cstand.adb (Create_Float_Types): Use C_Type_For to determine
4642 which C type should be used as the basis for the construction
