31
32 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
33
34 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
35 the declarations of single concurrent types because they fall in the
36 category of full type and object declarations.
37
38 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
39
40 * repinfo.adb (Compute_Max_Length): Skip _Parent component.
41 (List_Record_Layout): Likewise.
42
43 2018-05-28 Ed Schonberg <schonberg@adacore.com>
44
45 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
46 includes a call to function to which it applies. This may mean an
47 omission of an attribute reference 'Result, in particular if the
48 function is pqrameterless.
49
50 2018-05-28 Justin Squirek <squirek@adacore.com>
51
52 * sem_ch8.adb (Find_Expanded_Name): Add extra guard to make sure the
53 misresolved package name is not a case of mistaken identity.
54
55 2018-05-28 Yannick Moy <moy@adacore.com>
56
57 * sem_res.adb (Resolve_Range): Re-resolve the low bound of a range in
58 GNATprove mode, as the order of resolution (low then high) means that
59 all the information is not available when resolving the low bound the
60 first time.
61
62 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
63
64 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
65 end with the linker section, if any.
66 (List_Entities): Do not output the linker section for record types,
67 array types and variables.
68 (Print_Expr): Factor out common processing for unary operators and
69 special values. Adjust and reorder the various cases.
70 (List_Object_Info): End with the linker section, if any.
71 (List_Record_Info): Likewise.
72 (List_Type_Info): Do not start with a blank line.
73
74 2018-05-25 Nicolas Roche <roche@adacore.com>
75
76 * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure
77 that the result will be either -infinite or +infinite.
78
79 2018-05-25 Patrick Bernardi <bernardi@adacore.com>
80
81 * libgnat/s-parame.ads, libgnat/s-parame__vxworks.ads,
82 libgnat/s-parame__ae653.ads, libgnat/s-parame__hpux.ads (Size_Type):
83 Expand range of type to match the address space of the target.
84 (Task_Storage_Size): Remove unused type.
85
86 2018-05-25 Ed Schonberg <schonberg@adacore.com>
87
88 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
89 of a fixed point type and the parent is a multiplying operation,
90 resolve the operand with its own type because the context will impose a
91 resulting type on the result of the multiplication by means of
92 approriate conversion.
93
94 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
95
96 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
97 the in-place initialization aggregate created for pragmas
98 Initialize_Scalars or Normalize_Scalars is performed with checks
99 suppressed.
100
101 2018-05-25 Arnaud Charlet <charlet@adacore.com>
102
103 * exp_aggr.adb (Convert_To_Positional): Bump default for
104 Max_Others_Replicate to 32. Update comments.
105 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
106 (No_File_Info_Cache): Initialize separately.
107 * osint.adb (No_File_Info_Cache): Update initializer.
108
109 2018-05-25 Javier Miranda <miranda@adacore.com>
110
111 * sem_res.adb (Resolve_Membership_Op): Allow the use of the membership
112 test when the left operand is a class-wide interface and the right
113 operand is not a class-wide type.
114 * exp_ch4.adb (Tagged_Membership): Adding support for interface as the
115 left operand.
116
117 2018-05-25 Ed Schonberg <schonberg@adacore.com>
118
119 * exp_aggr.adb (Flatten): A quantified expression cannot be duplicated
120 in an others clause to prevent visibility issues with the generated
121 loop variable.
122 (Component_OK_For_Backend): Return false for a quantified expression.
123 (Check_Static_Component): Ditto.
124
125 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
126
127 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
128 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
129 into three distring cases rather than in one loop which attempts to
130 handle all three cases. This rewrite eliminates an issue where the last
131 frame of the stack cannot be freed, thus causing the memory range of a
132 new frame to approach the overflow point of the memory index type.
133 Since the overflow is logically treated as a
134 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
135 (SS_Allocate_Static): New routine. The routine factorizes the static
136 secondary stack-related code from the former SS_Allocate.
137
138 2018-05-25 Sergey Rybin <rybin@adacore.com>
139
140 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'
141 option for gnatelim.
142
143 2018-05-25 Ed Schonberg <schonberg@adacore.com>
144
145 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
146 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
147 is created when the proper body of the stub is analyzed.
148 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
149 is the proper body of a subunit, the cloned body must be inserted in
150 the declarative list that contains the stub.
151
152 2018-05-25 Justin Squirek <squirek@adacore.com>
153
154 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
155 generate code for 6.5(8-10) so that we don't get an assertion error
156 when dealing with an incomplete return type.
157
158 2018-05-25 Arnaud Charlet <charlet@adacore.com>
159
160 * pprint.adb (Expression_Name): Strip too long expressions to avoid
161 carrying very large strings.
162
163 2018-05-25 Patrick Bernardi <bernardi@adacore.com>
164
165 * switch-b.adb (Scan_Binder_Switches): binder switch -Q accepts Natural
166 numbers.
167
168 2018-05-25 Doug Rupp <rupp@adacore.com>
169
170 * tracebak.c (aarch64-linux): Implement.
171
172 2018-05-25 Justin Squirek <squirek@adacore.com>
173
174 * sem_ch8.adb: Minor reformatting.
175
176 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
177
178 * sem_util.adb (Iterate_Call_Parameters): Fix code convention and
179 assertions.
180
181 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
182
183 * einfo.adb, einfo.ads, exp_ch3.adb, exp_ch8.adb, exp_unst.adb,
184 pprint.adb, sem_ch12.adb, sem_ch3.adb, sem_prag.adb, sem_util.adb:
185 Minor reformatting.
186
187 2018-05-25 Ed Schonberg <schonberg@adacore.com>
188
189 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
190 Validate_Derived_Type_Instance, to verify that all interfaces
191 implemented by the formal type are also implemented by the actual. The
192 verification is complicated when an interface of the formal is declared
193 in a generic unit and the actual is declared in an instance of it.
194 There is currently no mechanism to relate an interface declared within
195 a generic to the corresponding interface in an instance, so we must
196 traverse the list of interfaces of the actual, looking for a name
197 match, and verifying that that interface is declared in an instance.
198
199 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
200
201 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
202 assertions; replace function versions of Next_Formal/Next_Actual with
203 their procedural versions (which are more concise).

226 for a formal derived type implements all the interfaces declared for
227 the formal.
228
229 2018-05-25 Yannick Moy <moy@adacore.com>
230
231 * sem_prag.adb (Check_Applicable_Policy): Deal specially with CodePeer

237 boolean type with convention C.
238 * libgnat/i-cexten.ads (bool): Change to boolean with convention C.
239 * gcc-interface/decl.c (gnat_to_gnu_entity): Add new local variable
240 FOREIGN and use it throughout the function.

266 (Note_Uplevel_Bound): Verify that the bound is declared in an enclosing
267 subprogram, as itype created for loops in pre/postcondition may appear
268 in loops at the library level.
269
270 2018-05-25 Ed Schonberg <schonberg@adacore.com>
271
272 * sem_ch13.adb (Build_Predicate_Functions): The predicate function
273 declaration is inserted into the tree and analyzed at that point, so
274 should not be reinserted when the body is constructed. Inside a
275 generic, ensure that the body is not inserted twice in the tree.

294
295 * fe.h (Set_Normalized_First_Bit): Declare.
296 (Set_Normalized_Position): Likewise.
297 * repinfo.adb (List_Record_Layout): Do not use irregular output for a
298 variable position. Fix minor spacing issue.
299 * gcc-interface/decl.c (annotate_rep): If a field has a variable
300 offset, compute the normalized position and annotate it in addition to
301 the bit offset.
302
303 2018-05-24 Eric Botcazou <ebotcazou@adacore.com>
304

326
327 * einfo.ads, einfo.adb (Is_Activation_Record): New flag on
328 in_parameters, used when unesting subprograms for LLVM, to indicate

335
336 2018-05-24 Yannick Moy <moy@adacore.com>

353
354 * sem_ch8.adb (Analyze_Use_Type): Do not assign the Prev_Use_Clause
355 link to a use_type clause if this would cause an infinite loop in the
356 machinery that detects redundant use clauses. This may happen when the
357 redundant clauses appear in the context of a child unit and the context
358 of its parent.
359
360 2018-05-24 Piotr Trojanek <trojanek@adacore.com>

1434 delegate the secondary stack management when there is no suitable
1435 transient context, and the transient scope was intended to manage the
1436 secondary stack because this causes premature reclamation. Change the
1437 transient scope creation logic by special casing assignment statements
1438 of controlled components for type initialization procedures.

1440 the comment on usage.
1441 (Find_Transient_Context): Change the initinte loop into a while loop.
1442 Iterations schemes and iterator specifications are not valid transient
1443 contexts because they rely on special processing. Assignment statements
1444 are now treated as a normal transient context, special cases are
1445 handled by the caller. Add special processing for pragma Check.
1446 (Is_OK_Construct): Removed. Its functionality has been merged in
1447 routine Find_Transient_Context.
1448 * sem_ch5.adb (Check_Call): Reimplemented. Add code to properly

1808 does not contain an internal call to a protected function. This
1809 completes the implementation of AI12-0166.

1812
1813 * ali.adb: Document the remaining letters available for ALI lines.
1814 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
1815 * ali.ads: Update type With_Record. Field
1816 Implicit_With_From_Instantiation is no longer in use. Add field
1817 Implicit_With.
1818 * csinfo.adb (CSinfo): Remove the setup for attribute
1819 Implicit_With_From_Instantiation.
1820 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
1821 either implicitly or explicitly withed.
1822 (Is_Implicit_With_Clause): New routine.
1823 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
1824 confusion with the with clause attribute by the same name.
1825 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
1826 * rtsfind.adb (Maybe_Add_With): Code cleanup.
1827 * sem_ch8.adb (Present_System_Aux): Code cleanup.
1828 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
1829 for a parent unit.
1830 (Implicit_With_On_Parent): Mark the with clause as generated for a
1831 parent unit.
1832 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
1833 instantiation are no longer marked as Implicit_With_From_Instantiation
1834 because they are already marked as implicit.
1835 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
1836 which marks implicit with clauses as related to an instantiation.
1837 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
1838 (Parent_With): New routine.
1839 (Set_Implicit_With_From_Instantiation): Removed.
1840 (Set_Parent_With): New routine.
1841 * sinfo.ads: Update the documentation of attribute Implicit_With.
1842 Remove attribute Implicit_With_From_Instantiation along with
1843 occurrences in nodes. Add attribute Parent_With along with occurrences
1844 in nodes.
1845 (Implicit_With_From_Instantiation): Removed along with pragma Inline.
1846 (Parent_With): New routine along with pragma Inline.
1847 (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
1848 (Set_Parent_With): New routine along with pragma Inline.
1849
1850 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1851
1852 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
1853 entity when the enclosing construct is a body.
1854
1855 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
1856
1857 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
1858 Secondary_Stack_Size handling as a pragma is now generated for the
1859 corresponding aspect instead of an attribute. Pragma expression is
1860 relocated instead of evaluated. Discriminant of the corresponding
1861 record type is referenced rather than the type discriminant.
1862 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
1863 Secondary_Stack_Size rep item checks to only look for the pragma rep.
1864 * sem_ch13.adb (Analyze_One_Aspect): Transform
1865 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
1866 because the attribute does not have visibility on a task type's
1867 discriminants when the type's definition is expanded.
1868 (Analyze_Attribute_Definition_Clause): Remove handling of
1869 Attribute_Secondary_Stack_Size.
1870 * snames.adb-tmpl, snames.ads-tmpl: Remove
1871 Attribute_Secondary_Stack_Size, no longer used.
1872
1873 2018-01-11 Justin Squirek <squirek@adacore.com>
1874
1875 * sem_ch8.adb: Minor comment fix.
1876
1877 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1878
1879 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
1880 individual action because the action may denote a complex expression,
1881 such as a case statement, which in turn may contain additional
1882 transient objects.
1883
1884 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1885
1886 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
1887 analysis on a copy of the expression with a copy of the index variable,
1888 because full expansion will rewrite construct into a loop with the
1889 original loop variable.
1890 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
1891 expression is an iterated component association. Full analysis takes
1892 place when construct is rewritten as a loop.
1893 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
1894 is not safe for in-place assignment.
1895 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
1896 entity with no homonym and no other entity in the scope.
1897
1898 2018-01-11 Justin Squirek <squirek@adacore.com>
1899
1900 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
1901 message to be printed on the pragma argument identifier.
1902
1903 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1904
1905 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
1906 entity of the generated invariant procedure in order to construct a
1907 proper entity chain.
1908
1909 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
1910
1911 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
1912 comment.
1913
1914 2018-01-11 Arnaud Charlet <charlet@adacore.com>
1915
1916 * einfo.ads, einfo.adb (Activation_Record_Component,
1917 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
1918 Allow E_Discriminant.
1919
1920 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
1921
1922 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
1923 for atomic access once the component size is taken into account and
1924 also do it if the component type is Atomic or Volatile_Full_Access.
1925
1926 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
1927
1928 * gnatvsn.ads: Bump copyright year.
