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

247 * a-contai.adb: New package body, implementing the above.
248 * a-convec.ads, a-convec.adb: Use tampering check machinery

253 Remove: function "=" (L, R : Elements_Array) return Boolean is
254 abstract; so we can call the predefined "=" on Elements_Array.
255 For "=" on Vectors: Previously, we returned True immediately if
256 Left'Address = Right'Address. That seems like a non-optimization
257 ("if X = X" is unusual), so removed that. Simplify by using
258 slice comparison ("=" on Element_Array will automatically call
259 "=" on the components, even if user defined).

1038 2015-06-01 Eric Botcazou <ebotcazou@adacore.com>
1040 * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Record_Type>: If the
1041 record has a parent field and a representation clause, make sure that
1042 it is properly aligned.

1052 * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Variable>: Deal with
1053 address clause on aliased object with unconstrained nominal subtype.

1057 template, be prepared for an empty array.
1058 (maybe_unconstrained_array): Likewise.

1064 result field by field.
1066 2015-05-31 Eric Botcazou <ebotcazou@adacore.com>
1068 * s-oscons-tmplt.c: Add explicit tests for Android alongside Linux.
1070 2015-05-30 Eric Botcazou <ebotcazou@adacore.com>
1072 * adaint.c: Test for __linux__ instead of linux and __sun__ instead
1073 of sun. Add missing leading underscore to AIX. Remove #elif 0.
1074 * adaint.h: Likewise.
1076 * cstreams.c: Likewise.
1078 * gsocket.h: Likewise.

1086 2015-05-28 Eric Botcazou <ebotcazou@adacore.com>
1088 * gcc-interface/utils.c (max_size) <tcc_binary>: Add special code to
1089 deal with the subtraction of a "negative" value in an unsigned type.
1091 2015-05-28 Eric Botcazou <ebotcazou@adacore.com>
1093 * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Subprogram_Type>: Do
1094 not error out on a return type which has a size that overflows if the
1095 return is done by invisible reference.
1097 2015-05-28 Eric Botcazou <ebotcazou@adacore.com>
1099 * gcc-interface/utils.c (gnat_pushdecl): Reunify the handling of array
1100 and pointer types wrt DECL_ORIGINAL_TYPE and adjust left and right.
1102 2015-05-28 Eric Botcazou <ebotcazou@adacore.com>
1104 * gcc-interface/gigi.h (gnat_stabilize_reference): Adjust.
1105 (rewrite_fn): Remove third parameter.
1106 (type_is_padding_self_referential): New inline predicate.
1107 (return_type_with_variable_size_p): Likewise.
1108 * gcc-interface/decl.c (allocatable_size_p): More around.
1109 (cannot_be_superflat_p): Rename into...
1110 (cannot_be_superflat ): ...this.
1111 (initial_value_needs_conversion): New predicate.
1112 (gnat_to_gnu_entity): Invoke type_is_padding_self_referential,
1113 initial_value_needs_conversion and adjust to above renaming.
1114 For a renaming, force the materialization if the inner expression
1115 is compound. Adjust calls to elaborate_reference and build a
1116 compound expression if needed.
1117 (struct er_dat): Add N field.
1118 (elaborate_reference_1): Remove N parameter and adjust.
1119 (elaborate_reference): Add INIT parameter and pass it in the call to
1120 gnat_rewrite_reference. Adjust initial expression.
1121 * gcc-interface/trans.c (Call_to_gnu): Treat renamings the same way as
1122 regular object declarations when it comes to creating a temporary.
1123 Adjust call to gnat_stabilize_reference and build a compound expression
1124 if needed. Invoke return_type_with_variable_size_p.
1125 (gnat_to_gnu): Invoke type_is_padding_self_referential. In case #4,
1126 return a call to a function unmodified if it returns with variable size
1127 and is also the initial expression in an object declaration.
1128 * gcc-interface/utils2.c (build_binary_op) <INIT_EXPR>: Use the RHS'
1129 type if it is a call to a function that returns with variable size.
1130 (build_unary_op): Invoke type_is_padding_self_referential.

1135 <COMPOUND_EXPR>: New case.
1137 2015-05-28 Ed Schonberg <schonberg@adacore.com>
1139 * sem_ch3.adb (Is_Visible_Component): Component is visible
1140 in a derived type if inherited through an ancestor that has a
1141 partial view of the original type holding the component, if the
1142 full view of that original type is in scope.
1143 * sem_util.ads (Get_Body_From_Stub): Works for all kinds of stubs.
1145 2015-05-28 Bob Duff <duff@adacore.com>
1147 * sem_util.adb (Requires_Transient_Scope): For definite untagged
1148 subtypes, we should never have to use the secondary stack. This moves
1149 toward that goal. But there are still cases that don't work.
1150 Here, we move the check for Is_Definite first, but add a
1151 special-purpose check for Has_Discrim_Dep_Array.
1153 2015-05-28 Bob Duff <duff@adacore.com>
1155 * sem_util.adb (Requires_Transient_Scope): Avoid returning
1156 function results on the secondary stack in so many cases.
1158 2015-05-28 Ed Schonberg <schonberg@adacore.com>
1160 * sem_util.adb (Wrong_Type): In any instance, do not emit error
1161 if type of expression is the partial view of the expected type.
1163 2015-05-28 Ed Schonberg <schonberg@adacore.com>
1165 * sem_res.adb (Resolve_Actuals): a) The replacement of formal
1166 names in named associations only needs to be done within an
1167 instance, on a call to a primitive of a formal derived type,
1168 where the actual subprogram may have different formal names than
1169 those of the primitive operation of the formal type.
1170 b) Defaulted parameters must be taken into account when obtaining
1171 the names of the formals of the actual subprogram being called.
1173 2015-05-28 Robert Dewar <dewar@adacore.com>
1175 * sem_ch13.adb, sem_disp.ads: Minor reformatting.
1177 2015-05-28 Ed Schonberg <schonberg@adacore.com>
1179 * sem_util.adb (Set_Debug_Info_Needed): For a private type
1180 whose full view is itself a derived private type, set flag on
1181 underlying full view as well, for proper gdb display.
1183 2015-05-28 Bob Duff <duff@adacore.com>
1185 * exp_tss.ads: Minor comment fix.
1186 * exp_ch3.adb (Build_Array_Init_Proc, Build_Record_Init_Proc):
1187 Inline init_procs when the type has controlled parts. Remove
1188 obsolete comments about those init_procs -- init_procs for
1189 such types are no longer complex. A typical init_proc just
1190 initializes the 'Tag field, and calls the parent init_proc
1191 (e.g. for Limited_Controlled), which calls the grandparent
1192 (for Root_Controlled), which does nothing. This all boils down
1193 to one instruction when inlined.
1194 * exp_ch7.adb (Create_Finalizer): Inline the finalizer.
1196 2015-05-28 Ed Schonberg <schonberg@adacore.com>
1198 * sem_ch4.adb (Analyze_Selected_Component): If the type to use
1199 is a derived type and is a generic actual, the selected component
1200 appears within an instance body, and the check over the type
1201 has failed, examine ancestor types for the desired component.
1202 (Find_Component_In_Instance): If record type is a derived type,
1203 examine all ancestors in order to locate desired component.
1205 2015-05-27 H.J. Lu <hongjiu.lu@intel.com>
1207 * gcc-interface/Makefile.in (TOOLS_LIBS): Add @NO_PIE_FLAG@.
1209 2015-05-27 Eric Botcazou <ebotcazou@adacore.com>
1211 * gcc-interface/trans.c (elaborate_all_entities): Do not elaborate an
1212 incomplete type coming from a limited_with and whose non-limited view
1213 comes from the main unit.
1215 2015-05-27 Eric Botcazou <ebotcazou@adacore.com>
1217 * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Variable>: Move down
1218 code applying atomic checks to the object.
1220 2015-05-27 Robert Dewar <dewar@adacore.com>

1224 2015-05-27 Bob Duff <duff@adacore.com>
1226 * exp_prag.adb (Expand_Pragma_Abort_Defer): Make
1227 pragma Abort_Defer do nothing if Abort_Allowed is False.
1229 2015-05-27 Arnaud Charlet <charlet@adacore.com>
1231 * exp_ch9.adb, sem_util.adb, sem_util.ads, s-stposu.adb, s-spsufi.ads,

1233 opt.ads, s-bignum.adb, output.ads, sem_ch13.adb, erroutc.ads,
1234 sem_disp.ads, exp_ch3.adb: Minor fixes of duplicate words in comments.
1236 2015-05-27 Doug Rupp <rupp@adacore.com>
1238 * adaint.c (__gnat_tmp_name) [vxworks]: Robustify and use for rtp as
1241 2015-05-27 Pierre-Marie de Rodat <derodat@adacore.com>
1243 * par_sco.adb (Process_Decision): Store sloc to
1244 condition/pragmas SCOs associations into a temporary table before
1245 moving them to the SCO_Raw_Hash_Table so that we can back them
1246 out just like we do for SCO entries that are simple decisions
1247 in an expression context.
1249 2015-05-27 Ed Schonberg <schonberg@adacore.com>
1251 * sem_ch6.adb (Process_Formals): A non-private formal type that
1252 is a limited view does not have a list of private dependents.
1254 2015-05-27 Ed Schonberg <schonberg@adacore.com>
1256 * exp_ch5.adb (Expand_N_Case_Statement): If the expression in
1257 the case statement is a compile-time known value, we look for a
1258 corresponding alternative to optimize the case statement into a
1259 single case. If the type has a static predicate and the expression
1260 does not satisfy the predicate, there is no legal alternative and
1261 this optimization is not applicable. Excecution is erroneous,
1262 or else if assertions are enabled, an exception will be raised
1263 earlier, at the point the expression is elaborated.
1265 2015-05-27 Robert Dewar <dewar@adacore.com>
1267 * sem_elab.adb (Check_Internal_Call_Continue): Suppress
1268 warning on Finalize, Adjust, or Initialize if type involved has
1271 2015-05-27 Ed Schonberg <schonberg@adacore.com>
1273 * sem_aux.adb, sem_aux.ads (First_Discriminant): Return empty when
1274 applied to a type with no known discriminants.
1276 2015-05-26 Robert Dewar <dewar@adacore.com>
1278 * errout.ads, sem_ch4.adb, sem_ch6.adb: Minor reformatting.
1280 2015-05-26 Bob Duff <duff@adacore.com>
1282 * sem_elab.adb (Check_A_Call): In the case where we're
1283 calling something in an instance of a generic package that is
1284 within this same unit (as the call), make sure we treat it
1285 as a call to an entity within the same unit. That is, call
1286 Check_Internal_Call, rather than putting "Elaborate_All(X)"
1287 on X, which would necessarily result in an elaboration cycle in
1288 static-elaboration mode.
1290 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
1292 * freeze.ads (Is_Atomic_VFA_Aggregate): Adjust profile.
1293 * freeze.adb (Is_Atomic_VFA_Aggregate): Change Entity
1294 parameter into Node parameter and remove Type parameter.
1295 Look at Is_Atomic_Or_VFA both on the type and on the object.

1297 * exp_aggr.adb (Expand_Record_Aggregate): Likewise.
1298 (Process_Atomic_Independent_Shared_Volatile): Remove code
1299 propagating Atomic or VFA from object to locally-defined type.
1301 2015-05-26 Bob Duff <duff@adacore.com>

1305 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
1307 * gcc-interface/trans.c (Attribute_to_gnu) <Attr_Min/Attr_Max>: Do not
1308 bother about NaN's if Machine_Overflows is true.
1310 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
1312 * gcc-interface/trans.c (gnat_to_gnu) <N_Object_Declaration>: Really
1313 force evaluation of the expression, if any, when the object has its
1314 elaboration delayed. Do not create a variable at global level.
1316 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
1318 * gcc-interface/trans.c (Attribute_to_gnu) <Attr_Machine>: Do not apply
1319 extra-precision trick to literals. Build SAVE_EXPR manually.
1321 * gcc-interface/misc.c (enumerate_modes): Add bypass for x86/x86-64.

1334 (elaborate_reference): Likewise.
1335 (gnat_to_gnu_entity): Call elaborate_reference to elaborate renamings
1336 and simplify associated code. Set const_flag to true consistently in
1337 conjunction with used_by_ref.

1339 pointers by renamed objects.
1340 (outer_atomic_access_required_p): Deal with renamings.

1358 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
1360 * gcc-interface/gigi.h (gnat_stabilize_reference): Adjust prototype.
1361 * gcc-interface/decl.c (gnat_to_gnu_entity): Do not rely on const_flag
1362 to detect constant renamings. Be prepared for specific pattern of
1363 renamed object based on function calls. Create a constant object
1364 for the renaming of a NULL_EXPR or of a CONSTRUCTOR. Adjust calls
1365 to gnat_stabilize_reference and tidy up. Remove redundant tests.
1366 (elaborate_expression_1): Remove obsolete test and tidy up.
1367 * gcc-interface/trans.c (Call_to_gnu): Do not stabilize In/Out or Out
1368 parameters passed by reference.
1369 (gnat_to_gnu) <N_Selected_Component>: Remove redundant protection again
1371 Use gnat_protect_expr instead of gnat_stabilize_reference for general

1374 (gnat_save_expr): Invoke it.

1384 * sinfo.ads: Minor reformatting.
1385 * sem_aux.ads: Clarify use of First_Discriminant.
1386 * sem_ch4.adb (Analyze_Explicit_Dereference): The use of a limited
1387 view is replaced with the non-limited view in an instance body,
1388 where the enclosing unit must have a regular with_clause on the
1390 * sem_ch12.adb (Install_Body): Freeze instantation after its
1391 body. Remove useless freeze nodes for incomplete actuals to
1392 prevent multiple generation of internal operations.
1393 (Instantiate_Package_Body): Set sloc of body appropriately when
1394 there are incomplete actuals and the instance body is placed in
1395 the body of the enclosing unit.
1396 * errout.ads: Consistent punctuation, better alignment and trivial
1398 * err_vars.ads: Fix typo.
1400 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>

1407 * sem_ch6.adb (Is_Non_Overriding_Operation,
1408 Get_Generic_Parent_Type): Handle properly the case of a derived

1414 * einfo.adb (Write_Field17_Name): Move E_Incomplete_Subtype
1416 (Write_Field19_Name): ...here.
1418 2015-05-26 Ed Schonberg <schonberg@adacore.com>
1420 * sem_ch13.adb: sem_ch13.adb (Add_Predicates): Undo analysis
1421 of original expression in ASIS mode: does not solve the ASIS
1422 problem of a usable type information, and crashes the back-end
1423 when performing type annotations.
1425 2015-05-26 Robert Dewar <dewar@adacore.com>
1427 * sem_disp.adb (Inherited_Subprograms): Add One_Only parameter.

1435 exp_ch3.adb: Minor reformatting.
1437 2015-05-26 Bob Duff <duff@adacore.com>
1439 * treepr.adb: Minor improvement to debugging routines (pp, pn)
1440 robustness. Rearrange the code so passing a nonexistent Node_Id
1441 prints "No such node" rather than crashing, and causing gdb to
1442 generate confusing messages.
1444 2015-05-26 Gary Dismukes <dismukes@adacore.com>
1446 * sem_util.adb: Minor typo fix.

2181 operation, replace the names of the actuals in named associations
2182 with the names of the actuals of the subprogram that is eventually
2183 executed. The names of the formals and the defaults can differ
2184 between the two operations when they are operations of a formal

2244 Instead of doing literally what the RM calls for, we do something
2245 equivalent that avoids expensive operations inside the loop. If the
2246 container package has appropriate Next, Pseudo_Reference,
2247 Element_Access, Get_Element_Access declarations, we invoke the
2249 * snames.ads-tmpl: Note speed improvement.

2358 (Install_Body): In the presence of actuals that incomplete types

2360 the declaration because full views have not been seen yet. Any
2361 use of the non-limited views in the instance body requires
2362 the presence of a regular with_clause in the enclosing unit,
2363 and will fail if this with_clause is missing. We place the
2364 instance body at the beginning of the enclosing body, which is
2365 the unit being compiled, and ensure that freeze nodes for the
2366 full views of the incomplete types appear before the instance.
