20 deal with the subtraction of a "negative" value in an unsigned type.
22 2015-05-28 Eric Botcazou <ebotcazou@adacore.com>
24 * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Subprogram_Type>: Do
25 not error out on a return type which has a size that overflows if the
26 return is done by invisible reference.
28 2015-05-28 Eric Botcazou <ebotcazou@adacore.com>
30 * gcc-interface/utils.c (gnat_pushdecl): Reunify the handling of array
31 and pointer types wrt DECL_ORIGINAL_TYPE and adjust left and right.
33 2015-05-28 Eric Botcazou <ebotcazou@adacore.com>
35 * gcc-interface/gigi.h (gnat_stabilize_reference): Adjust.
36 (rewrite_fn): Remove third parameter.
37 (type_is_padding_self_referential): New inline predicate.
38 (return_type_with_variable_size_p): Likewise.
39 * gcc-interface/decl.c (allocatable_size_p): More around.
40 (cannot_be_superflat_p): Rename into...
41 (cannot_be_superflat ): ...this.
42 (initial_value_needs_conversion): New predicate.
43 (gnat_to_gnu_entity): Invoke type_is_padding_self_referential,
44 initial_value_needs_conversion and adjust to above renaming.
45 For a renaming, force the materialization if the inner expression
46 is compound. Adjust calls to elaborate_reference and build a
47 compound expression if needed.
48 (struct er_dat): Add N field.
49 (elaborate_reference_1): Remove N parameter and adjust.
50 (elaborate_reference): Add INIT parameter and pass it in the call to

53 regular object declarations when it comes to creating a temporary.
54 Adjust call to gnat_stabilize_reference and build a compound expression
55 if needed. Invoke return_type_with_variable_size_p.
56 (gnat_to_gnu): Invoke type_is_padding_self_referential. In case #4,
57 return a call to a function unmodified if it returns with variable size
58 and is also the initial expression in an object declaration.
59 * gcc-interface/utils2.c (build_binary_op) <INIT_EXPR>: Use the RHS'
60 type if it is a call to a function that returns with variable size.
61 (build_unary_op): Invoke type_is_padding_self_referential.

63 (gnat_stabilize_reference): Add INIT parameter and pass it in the call
64 to gnat_rewrite_reference.
65 (gnat_rewrite_reference): Remove N, add INIT parameter and adjust.
66 <COMPOUND_EXPR>: New case.
68 2015-05-28 Ed Schonberg <schonberg@adacore.com>
70 * sem_ch3.adb (Is_Visible_Component): Component is visible
71 in a derived type if inherited through an ancestor that has a
72 partial view of the original type holding the component, if the
73 full view of that original type is in scope.
74 * sem_util.ads (Get_Body_From_Stub): Works for all kinds of stubs.
76 2015-05-28 Bob Duff <duff@adacore.com>
78 * sem_util.adb (Requires_Transient_Scope): For definite untagged
79 subtypes, we should never have to use the secondary stack. This moves
80 toward that goal. But there are still cases that don't work.
81 Here, we move the check for Is_Definite first, but add a
82 special-purpose check for Has_Discrim_Dep_Array.
84 2015-05-28 Bob Duff <duff@adacore.com>
86 * sem_util.adb (Requires_Transient_Scope): Avoid returning
87 function results on the secondary stack in so many cases.
89 2015-05-28 Ed Schonberg <schonberg@adacore.com>
91 * sem_util.adb (Wrong_Type): In any instance, do not emit error
92 if type of expression is the partial view of the expected type.
94 2015-05-28 Ed Schonberg <schonberg@adacore.com>
96 * sem_res.adb (Resolve_Actuals): a) The replacement of formal
97 names in named associations only needs to be done within an
98 instance, on a call to a primitive of a formal derived type,
99 where the actual subprogram may have different formal names than
100 those of the primitive operation of the formal type.
101 b) Defaulted parameters must be taken into account when obtaining
102 the names of the formals of the actual subprogram being called.
104 2015-05-28 Robert Dewar <dewar@adacore.com>
106 * sem_ch13.adb, sem_disp.ads: Minor reformatting.
108 2015-05-28 Ed Schonberg <schonberg@adacore.com>
110 * sem_util.adb (Set_Debug_Info_Needed): For a private type
111 whose full view is itself a derived private type, set flag on
112 underlying full view as well, for proper gdb display.
114 2015-05-28 Bob Duff <duff@adacore.com>
116 * exp_tss.ads: Minor comment fix.
117 * exp_ch3.adb (Build_Array_Init_Proc, Build_Record_Init_Proc):
118 Inline init_procs when the type has controlled parts. Remove
119 obsolete comments about those init_procs -- init_procs for
120 such types are no longer complex. A typical init_proc just
121 initializes the 'Tag field, and calls the parent init_proc
122 (e.g. for Limited_Controlled), which calls the grandparent
123 (for Root_Controlled), which does nothing. This all boils down
124 to one instruction when inlined.
125 * exp_ch7.adb (Create_Finalizer): Inline the finalizer.
127 2015-05-28 Ed Schonberg <schonberg@adacore.com>
129 * sem_ch4.adb (Analyze_Selected_Component): If the type to use
130 is a derived type and is a generic actual, the selected component
131 appears within an instance body, and the check over the type
132 has failed, examine ancestor types for the desired component.
133 (Find_Component_In_Instance): If record type is a derived type,
134 examine all ancestors in order to locate desired component.
136 2015-05-27 H.J. Lu <hongjiu.lu@intel.com>
138 * gcc-interface/Makefile.in (TOOLS_LIBS): Add @NO_PIE_FLAG@.
140 2015-05-27 Eric Botcazou <ebotcazou@adacore.com>
142 * gcc-interface/trans.c (elaborate_all_entities): Do not elaborate an
143 incomplete type coming from a limited_with and whose non-limited view
144 comes from the main unit.
146 2015-05-27 Eric Botcazou <ebotcazou@adacore.com>
148 * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Variable>: Move down
149 code applying atomic checks to the object.
151 2015-05-27 Robert Dewar <dewar@adacore.com>
153 * sem_aux.adb: Minor rewording.
155 2015-05-27 Bob Duff <duff@adacore.com>
157 * exp_prag.adb (Expand_Pragma_Abort_Defer): Make
158 pragma Abort_Defer do nothing if Abort_Allowed is False.
160 2015-05-27 Arnaud Charlet <charlet@adacore.com>

163 sem_elab.ads, g-comlin.ads, errout.ads, exp_ch6.adb, sem_ch4.adb,
164 opt.ads, s-bignum.adb, output.ads, sem_ch13.adb, erroutc.ads,
165 sem_disp.ads, exp_ch3.adb: Minor fixes of duplicate words in comments.
167 2015-05-27 Doug Rupp <rupp@adacore.com>
169 * adaint.c (__gnat_tmp_name) [vxworks]: Robustify and use for rtp as
170 well as kernel.
172 2015-05-27 Pierre-Marie de Rodat <derodat@adacore.com>
174 * par_sco.adb (Process_Decision): Store sloc to
175 condition/pragmas SCOs associations into a temporary table before
176 moving them to the SCO_Raw_Hash_Table so that we can back them
177 out just like we do for SCO entries that are simple decisions
178 in an expression context.
180 2015-05-27 Ed Schonberg <schonberg@adacore.com>
182 * sem_ch6.adb (Process_Formals): A non-private formal type that
183 is a limited view does not have a list of private dependents.
185 2015-05-27 Ed Schonberg <schonberg@adacore.com>
187 * exp_ch5.adb (Expand_N_Case_Statement): If the expression in
188 the case statement is a compile-time known value, we look for a
189 corresponding alternative to optimize the case statement into a
190 single case. If the type has a static predicate and the expression
191 does not satisfy the predicate, there is no legal alternative and
192 this optimization is not applicable. Excecution is erroneous,
193 or else if assertions are enabled, an exception will be raised
194 earlier, at the point the expression is elaborated.
196 2015-05-27 Robert Dewar <dewar@adacore.com>
198 * sem_elab.adb (Check_Internal_Call_Continue): Suppress
199 warning on Finalize, Adjust, or Initialize if type involved has
200 Warnings_Off set.
202 2015-05-27 Ed Schonberg <schonberg@adacore.com>
204 * sem_aux.adb, sem_aux.ads (First_Discriminant): Return empty when
205 applied to a type with no known discriminants.
207 2015-05-26 Robert Dewar <dewar@adacore.com>
209 * errout.ads, sem_ch4.adb, sem_ch6.adb: Minor reformatting.
211 2015-05-26 Bob Duff <duff@adacore.com>
213 * sem_elab.adb (Check_A_Call): In the case where we're
214 calling something in an instance of a generic package that is
215 within this same unit (as the call), make sure we treat it
216 as a call to an entity within the same unit. That is, call
217 Check_Internal_Call, rather than putting "Elaborate_All(X)"
218 on X, which would necessarily result in an elaboration cycle in
219 static-elaboration mode.
221 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
223 * freeze.ads (Is_Atomic_VFA_Aggregate): Adjust profile.
224 * freeze.adb (Is_Atomic_VFA_Aggregate): Change Entity
225 parameter into Node parameter and remove Type parameter.
226 Look at Is_Atomic_Or_VFA both on the type and on the object.
227 (Freeze_Entity): Adjust call to Is_Atomic_VFA_Aggregate.
228 * exp_aggr.adb (Expand_Record_Aggregate): Likewise.

230 propagating Atomic or VFA from object to locally-defined type.
232 2015-05-26 Bob Duff <duff@adacore.com>

236 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
238 * gcc-interface/trans.c (Attribute_to_gnu) <Attr_Min/Attr_Max>: Do not
239 bother about NaN's if Machine_Overflows is true.
241 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
243 * gcc-interface/trans.c (gnat_to_gnu) <N_Object_Declaration>: Really
244 force evaluation of the expression, if any, when the object has its
245 elaboration delayed. Do not create a variable at global level.
247 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
249 * gcc-interface/trans.c (Attribute_to_gnu) <Attr_Machine>: Do not apply
250 extra-precision trick to literals. Build SAVE_EXPR manually.
252 * gcc-interface/misc.c (enumerate_modes): Add bypass for x86/x86-64.
254 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>

267 and simplify associated code. Set const_flag to true consistently in
268 conjunction with used_by_ref.
269 * gcc-interface/trans.c (Identifier_to_gnu): Always replace renaming
270 pointers by renamed objects.
271 (outer_atomic_access_required_p): Deal with renamings.
272 (Compilation_Unit_to_gnu): Do not call
273 invalidate_global_nonconstant_renamings.

292 * gcc-interface/decl.c (gnat_to_gnu_entity): Do not rely on const_flag
293 to detect constant renamings. Be prepared for specific pattern of
294 renamed object based on function calls. Create a constant object
295 for the renaming of a NULL_EXPR or of a CONSTRUCTOR. Adjust calls
296 to gnat_stabilize_reference and tidy up. Remove redundant tests.
297 (elaborate_expression_1): Remove obsolete test and tidy up.
298 * gcc-interface/trans.c (Call_to_gnu): Do not stabilize In/Out or Out
299 parameters passed by reference.
300 (gnat_to_gnu) <N_Selected_Component>: Remove redundant protection again
301 side-effects.
302 Use gnat_protect_expr instead of gnat_stabilize_reference for general
303 protection against side-effects.
304 * gcc-interface/utils2.c (gnat_stable_expr_p): New predicate.
305 (gnat_save_expr): Invoke it.
306 (gnat_protect_expr): Likewise.

308 of TREE_THIS_NOTRAP.
309 (gnat_stabilize_reference): Remove parameter and adjust throughout.

315 * sinfo.ads: Minor reformatting.
316 * sem_aux.ads: Clarify use of First_Discriminant.
317 * sem_ch4.adb (Analyze_Explicit_Dereference): The use of a limited
318 view is replaced with the non-limited view in an instance body,
319 where the enclosing unit must have a regular with_clause on the
320 relevant unit.
321 * sem_ch12.adb (Install_Body): Freeze instantation after its
322 body. Remove useless freeze nodes for incomplete actuals to
323 prevent multiple generation of internal operations.
324 (Instantiate_Package_Body): Set sloc of body appropriately when
325 there are incomplete actuals and the instance body is placed in
326 the body of the enclosing unit.
327 * errout.ads: Consistent punctuation, better alignment and trivial
328 typos in comments.
329 * err_vars.ads: Fix typo.
331 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>

338 * sem_ch6.adb (Is_Non_Overriding_Operation,
339 Get_Generic_Parent_Type): Handle properly the case of a derived
340 scalar type by using the first subtype rather than its generated
341 anonymous base type.
343 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
345 * einfo.adb (Write_Field17_Name): Move E_Incomplete_Subtype
346 case to...
347 (Write_Field19_Name): ...here.
349 2015-05-26 Ed Schonberg <schonberg@adacore.com>
351 * sem_ch13.adb: sem_ch13.adb (Add_Predicates): Undo analysis
352 of original expression in ASIS mode: does not solve the ASIS
353 problem of a usable type information, and crashes the back-end
354 when performing type annotations.
356 2015-05-26 Robert Dewar <dewar@adacore.com>
358 * sem_disp.adb (Inherited_Subprograms): Add One_Only parameter.

365 exp_ch6.adb, sem_ch6.adb, sem_ch8.adb, sem_ch11.adb, sem_ch13.adb,
366 exp_ch3.adb: Minor reformatting.
368 2015-05-26 Bob Duff <duff@adacore.com>
370 * treepr.adb: Minor improvement to debugging routines (pp, pn)
371 robustness. Rearrange the code so passing a nonexistent Node_Id
372 prints "No such node" rather than crashing, and causing gdb to
373 generate confusing messages.
375 2015-05-26 Gary Dismukes <dismukes@adacore.com>

613 sem_util.adb: Change the sense of Is_Indefinite_Subtype to be
614 Is_Definite_Subtype. This is an improvement to readability (the double

732 subtype are immediately visible if we are within their scope. This
733 may be needed when a procedure body is both the parent of an
734 instantiated child unit, and is itself used to inline a local
735 function.

775 * exp_ch6.adb (Expand_Actuals): For a function call with in-out
776 parameters that is rewritten as an expression_with_actions,
777 we preserve the original function call node for further use by
778 the caller (typically Expand_Call). In the presence of validity
779 checks, that function call, though it is labelled Analyzed to
780 prevent an infinite recursion, may be rewritten as a temporary
781 by Remove_Side_Effects. Ensure that the caller has access to
782 the original function call to continue expansion.

1113 with the names of the actuals of the subprogram that is eventually
1114 executed. The names of the formals and the defaults can differ
1115 between the two operations when they are operations of a formal
1116 derived type.
1118 2015-05-22 Bob Duff <duff@adacore.com>
1120 * a-convec.ads, a-convec.adb (Append): Check for fast path. Split
1121 out slow path into separate procedure. Inline Append. Fast path
1122 now avoids calling Insert.
1123 (Finalize): Do the busy checking last, so the container gets emptied.
1124 (Insert, Insert_Space): Remove redundancy.
1126 2015-05-22 Robert Dewar <dewar@adacore.com>

1174 * exp_ch5.adb: Speed up "for ... of" loops for predefined containers.
1175 Instead of doing literally what the RM calls for, we do something
1176 equivalent that avoids expensive operations inside the loop. If the
1177 container package has appropriate Next, Pseudo_Reference,
1178 Element_Access, Get_Element_Access declarations, we invoke the
1179 optimization.
1180 * snames.ads-tmpl: Note speed improvement.

1288 freeze nodes for actuals.
1289 (Install_Body): In the presence of actuals that incomplete types
1290 from a limited view, the instance body cannot be placed after
1291 the declaration because full views have not been seen yet. Any
1292 use of the non-limited views in the instance body requires
1293 the presence of a regular with_clause in the enclosing unit,
1294 and will fail if this with_clause is missing. We place the
1295 instance body at the beginning of the enclosing body, which is
1296 the unit being compiled, and ensure that freeze nodes for the
1297 full views of the incomplete types appear before the instance.

2147 * sem_util.adb (Build_Default_Subtype): If the subtype is created
2148 for a record discriminant, do not analyze the declarztion at

2610 type to retrieve designated type, because the purported access
2611 type may be a partial (private) view, when it is declared in

2724 2015-03-02 Bob Duff <duff@adacore.com>
2726 * sem_ch6.adb (Check_Private_Overriding): Refine the legality
2727 checks here. It used to check that the function is merely
2728 overriding SOMEthing. Now it checks that the function is
2729 overriding a corresponding public operation. This is a correction

2767 original type for the new declaration, do not define a stub
2768 declaration for it.

2770 pointer types when they point to the same type.
2772 2015-03-02 Hristian Kirtchev <kirtchev@adacore.com>

2826 expanding a 'Input attribute reference for a class-wide type,
2827 do not generate a separate object declaration for the controlling
2828 tag dummy object; instead, generate the expression inline in the
2829 dispatching call. Otherwise, the declaration (which involves a
2830 call to String'Input, returning a dynamically sized value on the
2831 secondary stack) will be expanded outside of proper secondary
2832 stack mark/release operations, and will thus cause a secondary
2833 stack leak.
2835 2015-03-02 Hristian Kirtchev <kirtchev@adacore.com>
2837 * checks.adb (Add_Validity_Check): Change the names of all

4741 * sem_ch13.adb (Analyze_Aspect_Specifications): For aspects
4742 that specify stream subprograms, if the prefix is a class-wide
4743 type then the generated attribute definition clause must apply
4744 to the same class-wide type.
4745 (Default_Iterator): An iterator defined by an aspect of some
4746 container type T must have a first parameter of type T, T'class,
4747 or an access to such (from code reading RM 5.5.1 (2/3)).

4755 * set_targ.ads (C_Type_For): New function. Return the name of
4756 a C type supported by the back-end and suitable as a basis to
4757 construct the standard Ada floating point type identified by
4758 the T parameter. This is used as a common ground to feed both
4759 ttypes values and the GNAT tree nodes for the standard floating
4760 point types.
4761 * set_targ.adb (Long_Double_Index): The index at which "long
4762 double" gets registered in the FPT_Mode_Table. This is useful to
4763 know whether we have a "long double" available at all and get at
4764 it's characteristics without having to search the FPT_Mode_Table
4765 when we need to decide which C type should be used as the
4766 basis for Long_Long_Float in Ada.
4767 (Register_Float_Type): Fill Long_Double_Index.
4768 (FPT_Mode_Index_For): New function. Return the index in

4772 FPT_Mode_Table that designates the entry for a back-end type
4773 suitable as a basis to construct the standard Ada floating point
4774 type identified by the input T parameter.
4775 (elaboration code): Register_Back_End_Types unconditionally,
4776 so C_Type_For can operate regardless of -gnateT. Do it
4777 early so we can query it for the floating point sizes, via
4778 FPT_Mode_Index_For. Initialize Float_Size, Double_Size and
4779 Long_Double_Size from the FPT_Mode_Table, as cstand will do.
4780 * cstand.adb (Create_Float_Types): Use C_Type_For to determine
4781 which C type should be used as the basis for the construction
4782 of the Standard Ada floating point types.
4783 * get_targ.ads (Get_Float_Size, Get_Double_Size,
4784 Get_Long_Double_Size): Remove.
