242 on "=" composing, but that doesn't quite work -- we want the "="

261 * a-contai.adb: New package body, implementing the above.
262 * a-convec.ads, a-convec.adb: Use tampering check machinery
264 Disable all checking code when checks are suppressed.
265 Simplify many of the operations. Implement "&" in terms of Append,
266 rather than "by hand".
267 Remove: function "=" (L, R : Elements_Array) return Boolean is
268 abstract; so we can call the predefined "=" on Elements_Array.
269 For "=" on Vectors: Previously, we returned True immediately if
270 Left'Address = Right'Address. That seems like a non-optimization
271 ("if X = X" is unusual), so removed that. Simplify by using
272 slice comparison ("=" on Element_Array will automatically call
273 "=" on the components, even if user defined).

1039 if it is not in the main code unit.
1041 2015-06-01 Eric Botcazou <ebotcazou@adacore.com>
1043 * gcc-interface/utils.c (create_var_decl_1): If an assembler name is
1044 specified, let the target mangle it before settting.
1045 (create_subprog_decl): Likewise and move this treatment last.
1047 2015-06-01 Eric Botcazou <ebotcazou@adacore.com>
1049 * gcc-interface/lang-specs.h (TARGET_VXWORKS_RTP): Move substitution to
1050 before first -gnatez switch. Simplify and add trailing space.
1052 2015-06-01 Eric Botcazou <ebotcazou@adacore.com>
1054 * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Record_Type>: If the
1055 record has a parent field and a representation clause, make sure that
1056 it is properly aligned.
1058 2015-06-01 Eric Botcazou <ebotcazou@adacore.com>
1060 * gcc-interface/trans.c (lvalue_required_p) <N_Indexed_Component>: Deal
1061 with character and enumeration literals as index values.
1063 2015-06-01 Eric Botcazou <ebotcazou@adacore.com>

1066 * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Variable>: Deal with
1067 address clause on aliased object with unconstrained nominal subtype.
1068 Mark the aligning variable as artificial, do not convert the address
1069 expression immediately but mark it as constant instead.

1071 template, be prepared for an empty array.
1072 (maybe_unconstrained_array): Likewise.
1073 * gcc-interface/utils2.c (known_alignment) <POINTER_PLUS_EXPR>: Deal
1074 with the pattern built for aligning types.

1078 result field by field.
1080 2015-05-31 Eric Botcazou <ebotcazou@adacore.com>
1082 * s-oscons-tmplt.c: Add explicit tests for Android alongside Linux.
1084 2015-05-30 Eric Botcazou <ebotcazou@adacore.com>
1086 * adaint.c: Test for __linux__ instead of linux and __sun__ instead
1087 of sun. Add missing leading underscore to AIX. Remove #elif 0.
1088 * adaint.h: Likewise.
1090 * cstreams.c: Likewise.
1092 * gsocket.h: Likewise.
1093 * init.c: Likewise. Test for __i386__ instead of i386.
1095 * s-oscons-tmplt.c: Likewise.

1100 2015-05-28 Eric Botcazou <ebotcazou@adacore.com>
1102 * gcc-interface/utils.c (max_size) <tcc_binary>: Add special code to
1103 deal with the subtraction of a "negative" value in an unsigned type.
1105 2015-05-28 Eric Botcazou <ebotcazou@adacore.com>
1107 * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Subprogram_Type>: Do
1108 not error out on a return type which has a size that overflows if the
1109 return is done by invisible reference.
1111 2015-05-28 Eric Botcazou <ebotcazou@adacore.com>
1113 * gcc-interface/utils.c (gnat_pushdecl): Reunify the handling of array
1114 and pointer types wrt DECL_ORIGINAL_TYPE and adjust left and right.
1116 2015-05-28 Eric Botcazou <ebotcazou@adacore.com>
1118 * gcc-interface/gigi.h (gnat_stabilize_reference): Adjust.
1119 (rewrite_fn): Remove third parameter.
1120 (type_is_padding_self_referential): New inline predicate.
1121 (return_type_with_variable_size_p): Likewise.
1122 * gcc-interface/decl.c (allocatable_size_p): More around.
1123 (cannot_be_superflat_p): Rename into...
1124 (cannot_be_superflat ): ...this.
1125 (initial_value_needs_conversion): New predicate.
1126 (gnat_to_gnu_entity): Invoke type_is_padding_self_referential,
1127 initial_value_needs_conversion and adjust to above renaming.
1128 For a renaming, force the materialization if the inner expression
1129 is compound. Adjust calls to elaborate_reference and build a
1130 compound expression if needed.
1131 (struct er_dat): Add N field.
1132 (elaborate_reference_1): Remove N parameter and adjust.
1133 (elaborate_reference): Add INIT parameter and pass it in the call to
1134 gnat_rewrite_reference. Adjust initial expression.
1135 * gcc-interface/trans.c (Call_to_gnu): Treat renamings the same way as
1136 regular object declarations when it comes to creating a temporary.
1137 Adjust call to gnat_stabilize_reference and build a compound expression
1138 if needed. Invoke return_type_with_variable_size_p.
1139 (gnat_to_gnu): Invoke type_is_padding_self_referential. In case #4,
1140 return a call to a function unmodified if it returns with variable size
1141 and is also the initial expression in an object declaration.
1142 * gcc-interface/utils2.c (build_binary_op) <INIT_EXPR>: Use the RHS'
1143 type if it is a call to a function that returns with variable size.
1144 (build_unary_op): Invoke type_is_padding_self_referential.
1145 (gnat_stabilize_reference_1): Remove N parameter and adjust.
1146 (gnat_stabilize_reference): Add INIT parameter and pass it in the call
1147 to gnat_rewrite_reference.

1149 <COMPOUND_EXPR>: New case.
1151 2015-05-28 Ed Schonberg <schonberg@adacore.com>
1153 * sem_ch3.adb (Is_Visible_Component): Component is visible
1154 in a derived type if inherited through an ancestor that has a
1155 partial view of the original type holding the component, if the
1156 full view of that original type is in scope.
1157 * sem_util.ads (Get_Body_From_Stub): Works for all kinds of stubs.
1159 2015-05-28 Bob Duff <duff@adacore.com>
1161 * sem_util.adb (Requires_Transient_Scope): For definite untagged
1162 subtypes, we should never have to use the secondary stack. This moves
1163 toward that goal. But there are still cases that don't work.
1164 Here, we move the check for Is_Definite first, but add a
1165 special-purpose check for Has_Discrim_Dep_Array.
1167 2015-05-28 Bob Duff <duff@adacore.com>
1169 * sem_util.adb (Requires_Transient_Scope): Avoid returning
1170 function results on the secondary stack in so many cases.
1172 2015-05-28 Ed Schonberg <schonberg@adacore.com>
1174 * sem_util.adb (Wrong_Type): In any instance, do not emit error
1175 if type of expression is the partial view of the expected type.
1177 2015-05-28 Ed Schonberg <schonberg@adacore.com>
1179 * sem_res.adb (Resolve_Actuals): a) The replacement of formal
1180 names in named associations only needs to be done within an
1181 instance, on a call to a primitive of a formal derived type,
1182 where the actual subprogram may have different formal names than
1183 those of the primitive operation of the formal type.
1184 b) Defaulted parameters must be taken into account when obtaining
1185 the names of the formals of the actual subprogram being called.
1187 2015-05-28 Robert Dewar <dewar@adacore.com>
1189 * sem_ch13.adb, sem_disp.ads: Minor reformatting.
1191 2015-05-28 Ed Schonberg <schonberg@adacore.com>
1193 * sem_util.adb (Set_Debug_Info_Needed): For a private type
1194 whose full view is itself a derived private type, set flag on
1195 underlying full view as well, for proper gdb display.
1197 2015-05-28 Bob Duff <duff@adacore.com>
1199 * exp_tss.ads: Minor comment fix.
1200 * exp_ch3.adb (Build_Array_Init_Proc, Build_Record_Init_Proc):
1201 Inline init_procs when the type has controlled parts. Remove
1202 obsolete comments about those init_procs -- init_procs for
1203 such types are no longer complex. A typical init_proc just
1204 initializes the 'Tag field, and calls the parent init_proc
1205 (e.g. for Limited_Controlled), which calls the grandparent
1206 (for Root_Controlled), which does nothing. This all boils down
1207 to one instruction when inlined.
1208 * exp_ch7.adb (Create_Finalizer): Inline the finalizer.
1210 2015-05-28 Ed Schonberg <schonberg@adacore.com>
1212 * sem_ch4.adb (Analyze_Selected_Component): If the type to use
1213 is a derived type and is a generic actual, the selected component
1214 appears within an instance body, and the check over the type
1215 has failed, examine ancestor types for the desired component.
1216 (Find_Component_In_Instance): If record type is a derived type,
1217 examine all ancestors in order to locate desired component.
1219 2015-05-27 H.J. Lu <hongjiu.lu@intel.com>
1221 * gcc-interface/Makefile.in (TOOLS_LIBS): Add @NO_PIE_FLAG@.
1223 2015-05-27 Eric Botcazou <ebotcazou@adacore.com>
1225 * gcc-interface/trans.c (elaborate_all_entities): Do not elaborate an
1226 incomplete type coming from a limited_with and whose non-limited view
1227 comes from the main unit.
1229 2015-05-27 Eric Botcazou <ebotcazou@adacore.com>
1231 * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Variable>: Move down
1232 code applying atomic checks to the object.
1234 2015-05-27 Robert Dewar <dewar@adacore.com>

1238 2015-05-27 Bob Duff <duff@adacore.com>
1240 * exp_prag.adb (Expand_Pragma_Abort_Defer): Make
1241 pragma Abort_Defer do nothing if Abort_Allowed is False.
1243 2015-05-27 Arnaud Charlet <charlet@adacore.com>
1245 * exp_ch9.adb, sem_util.adb, sem_util.ads, s-stposu.adb, s-spsufi.ads,
1246 sem_elab.ads, g-comlin.ads, errout.ads, exp_ch6.adb, sem_ch4.adb,
1247 opt.ads, s-bignum.adb, output.ads, sem_ch13.adb, erroutc.ads,
1248 sem_disp.ads, exp_ch3.adb: Minor fixes of duplicate words in comments.
1250 2015-05-27 Doug Rupp <rupp@adacore.com>
1252 * adaint.c (__gnat_tmp_name) [vxworks]: Robustify and use for rtp as
1255 2015-05-27 Pierre-Marie de Rodat <derodat@adacore.com>
1257 * par_sco.adb (Process_Decision): Store sloc to
1258 condition/pragmas SCOs associations into a temporary table before
1259 moving them to the SCO_Raw_Hash_Table so that we can back them
1260 out just like we do for SCO entries that are simple decisions
1261 in an expression context.
1263 2015-05-27 Ed Schonberg <schonberg@adacore.com>
1265 * sem_ch6.adb (Process_Formals): A non-private formal type that
1266 is a limited view does not have a list of private dependents.
1268 2015-05-27 Ed Schonberg <schonberg@adacore.com>
1270 * exp_ch5.adb (Expand_N_Case_Statement): If the expression in
1271 the case statement is a compile-time known value, we look for a
1272 corresponding alternative to optimize the case statement into a
1273 single case. If the type has a static predicate and the expression
1274 does not satisfy the predicate, there is no legal alternative and
1275 this optimization is not applicable. Excecution is erroneous,
1276 or else if assertions are enabled, an exception will be raised
1277 earlier, at the point the expression is elaborated.
1279 2015-05-27 Robert Dewar <dewar@adacore.com>
1281 * sem_elab.adb (Check_Internal_Call_Continue): Suppress
1282 warning on Finalize, Adjust, or Initialize if type involved has
1285 2015-05-27 Ed Schonberg <schonberg@adacore.com>
1287 * sem_aux.adb, sem_aux.ads (First_Discriminant): Return empty when
1288 applied to a type with no known discriminants.
1290 2015-05-26 Robert Dewar <dewar@adacore.com>
1292 * errout.ads, sem_ch4.adb, sem_ch6.adb: Minor reformatting.
1294 2015-05-26 Bob Duff <duff@adacore.com>
1296 * sem_elab.adb (Check_A_Call): In the case where we're
1297 calling something in an instance of a generic package that is
1298 within this same unit (as the call), make sure we treat it
1299 as a call to an entity within the same unit. That is, call
1300 Check_Internal_Call, rather than putting "Elaborate_All(X)"
1301 on X, which would necessarily result in an elaboration cycle in
1302 static-elaboration mode.
1304 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
1306 * freeze.ads (Is_Atomic_VFA_Aggregate): Adjust profile.
1307 * freeze.adb (Is_Atomic_VFA_Aggregate): Change Entity
1308 parameter into Node parameter and remove Type parameter.
1309 Look at Is_Atomic_Or_VFA both on the type and on the object.
1310 (Freeze_Entity): Adjust call to Is_Atomic_VFA_Aggregate.
1311 * exp_aggr.adb (Expand_Record_Aggregate): Likewise.
1312 (Process_Atomic_Independent_Shared_Volatile): Remove code
1313 propagating Atomic or VFA from object to locally-defined type.
1315 2015-05-26 Bob Duff <duff@adacore.com>
1317 * exp_ch7.adb: Minor comment fix.
1319 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
1321 * gcc-interface/trans.c (Attribute_to_gnu) <Attr_Min/Attr_Max>: Do not
1322 bother about NaN's if Machine_Overflows is true.
1324 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
1326 * gcc-interface/trans.c (gnat_to_gnu) <N_Object_Declaration>: Really
1327 force evaluation of the expression, if any, when the object has its
1328 elaboration delayed. Do not create a variable at global level.
1330 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
1332 * gcc-interface/trans.c (Attribute_to_gnu) <Attr_Machine>: Do not apply
1333 extra-precision trick to literals. Build SAVE_EXPR manually.
1335 * gcc-interface/misc.c (enumerate_modes): Add bypass for x86/x86-64.

1348 (elaborate_reference): Likewise.
1349 (gnat_to_gnu_entity): Call elaborate_reference to elaborate renamings
1350 and simplify associated code. Set const_flag to true consistently in
1351 conjunction with used_by_ref.
1352 * gcc-interface/trans.c (Identifier_to_gnu): Always replace renaming
1353 pointers by renamed objects.
1354 (outer_atomic_access_required_p): Deal with renamings.

1366 (gnat_stabilize_reference_1): Adjust.
1367 (gnat_stabilize_reference): Call gnat_stabilize_reference_1 through
1368 gnat_rewrite_reference and move bulk of code to...
1369 (gnat_rewrite_reference): ...here. New global function.
1370 (gnat_constant_reference_p): Delete.
1372 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
1374 * gcc-interface/gigi.h (gnat_stabilize_reference): Adjust prototype.
1375 * gcc-interface/decl.c (gnat_to_gnu_entity): Do not rely on const_flag
1376 to detect constant renamings. Be prepared for specific pattern of
1377 renamed object based on function calls. Create a constant object
1378 for the renaming of a NULL_EXPR or of a CONSTRUCTOR. Adjust calls
1379 to gnat_stabilize_reference and tidy up. Remove redundant tests.
1380 (elaborate_expression_1): Remove obsolete test and tidy up.
1381 * gcc-interface/trans.c (Call_to_gnu): Do not stabilize In/Out or Out
1382 parameters passed by reference.
1383 (gnat_to_gnu) <N_Selected_Component>: Remove redundant protection again
1385 Use gnat_protect_expr instead of gnat_stabilize_reference for general
1386 protection against side-effects.

1388 (gnat_save_expr): Invoke it.

1398 * sinfo.ads: Minor reformatting.
1399 * sem_aux.ads: Clarify use of First_Discriminant.
1400 * sem_ch4.adb (Analyze_Explicit_Dereference): The use of a limited
1401 view is replaced with the non-limited view in an instance body,
1402 where the enclosing unit must have a regular with_clause on the
1404 * sem_ch12.adb (Install_Body): Freeze instantation after its
1405 body. Remove useless freeze nodes for incomplete actuals to
1406 prevent multiple generation of internal operations.
1407 (Instantiate_Package_Body): Set sloc of body appropriately when
1408 there are incomplete actuals and the instance body is placed in
1409 the body of the enclosing unit.
1410 * errout.ads: Consistent punctuation, better alignment and trivial
1412 * err_vars.ads: Fix typo.
1414 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
1416 * sem_ch8.adb (Analyze_Object_Renaming): Lift restriction on
1417 components of Volatile_Full_Access objects.

1421 * sem_ch6.adb (Is_Non_Overriding_Operation,
1422 Get_Generic_Parent_Type): Handle properly the case of a derived

1428 * einfo.adb (Write_Field17_Name): Move E_Incomplete_Subtype
1430 (Write_Field19_Name): ...here.
1432 2015-05-26 Ed Schonberg <schonberg@adacore.com>
1434 * sem_ch13.adb: sem_ch13.adb (Add_Predicates): Undo analysis
1435 of original expression in ASIS mode: does not solve the ASIS
1436 problem of a usable type information, and crashes the back-end
1437 when performing type annotations.
1439 2015-05-26 Robert Dewar <dewar@adacore.com>
1441 * sem_disp.adb (Inherited_Subprograms): Add One_Only parameter.

1449 exp_ch3.adb: Minor reformatting.
1451 2015-05-26 Bob Duff <duff@adacore.com>
1453 * treepr.adb: Minor improvement to debugging routines (pp, pn)
1454 robustness. Rearrange the code so passing a nonexistent Node_Id
1455 prints "No such node" rather than crashing, and causing gdb to
1456 generate confusing messages.
1458 2015-05-26 Gary Dismukes <dismukes@adacore.com>
1460 * sem_util.adb: Minor typo fix.

2258 Instead of doing literally what the RM calls for, we do something
2259 equivalent that avoids expensive operations inside the loop. If the
2260 container package has appropriate Next, Pseudo_Reference,
2261 Element_Access, Get_Element_Access declarations, we invoke the

2372 (Install_Body): In the presence of actuals that incomplete types

2374 the declaration because full views have not been seen yet. Any
2375 use of the non-limited views in the instance body requires
2376 the presence of a regular with_clause in the enclosing unit,
2377 and will fail if this with_clause is missing. We place the
2378 instance body at the beginning of the enclosing body, which is
2379 the unit being compiled, and ensure that freeze nodes for the
2380 full views of the incomplete types appear before the instance.

5862 Long_Double_Size from the FPT_Mode_Table, as cstand will do.
5863 * cstand.adb (Create_Float_Types): Use C_Type_For to determine
