546 * sem_ch3.adb (Derive_Interface_Subprogram): Fix
547 Is_Abstract_Subprogram, which might have been calculated
548 incorrectly, because we're passing Ultimate_Alias (Subp) (and

554 * sem_ch13.adb (Check_Iterator_Functions): When

592 recheck the consistency betwen the freeze point and the end of
593 declarations for the expression in an aspect specification,
594 because it was done already in the analysis of the generic.

596 may produce spurious errors when the generic is a child unit
597 that references entities in the parent (which might not be in

1510 * sem_attr.adb (Analyze_Attribute, case Loop_Entry): The loop to
1511 which the attribute applies comes from source, not from expansion

1796 * sem_ch13.adb (Analyze_One_Aspect): Avoid

1800 * restrict.ads: minor whitespace cleanup in comment
1802 2015-10-20 Bob Duff <duff@adacore.com>

1823 * a-rbtgso.adb, a-rbtgso.ads: Change all the predefined containers
1824 to share the tampering machinery in Ada.Containers.Helpers. This
1825 reduces the amount of duplicated code, and takes advantage of
1826 efficiency improvements in Helpers.
1827 Protect all run-time checks and supporting machinery with "if
1828 Checks" or "if T_Check", so this code can be suppressed with
1829 pragma Suppress or -gnatp.
1830 Add Pseudo_Reference and Get_Element_Access to remaining

1838 visible everywhere it needs to be (e.g. in the package
1839 Ada.Containers.Red_Black_Trees, Generic_Tree_Types wants to have

1947 * a-coinve.ads, a-coinve.adb: Do the same efficiency
1948 improvements that were already done in the definite case
1949 (Ada.Containers.Vectors, i.e. a-convec). This includes the
1950 ability to suppress checks, the fast path for Append, inlining
1951 as appropriate, and special-casing of "for ... of" loops. Reuse
1952 the tampering machinery that is now in Ada.Containers. Simplify
1954 * a-convec.ads, a-convec.adb: Change the code to be more similar
1956 * a-finali.ads, a-finali.adb: Expose the "null"-ness of the

1972 2015-10-20 Bob Duff <duff@adacore.com>
1974 * debug.adb, expander.adb: Implement -gnatd.B switch, which
1975 triggers a bug box when an abort_statement is seen. This is
1976 useful for testing Comperr.Compiler_Abort.
1977 * gnat1drv.adb: Trigger bug box on all exceptions other than
1978 Unrecoverable_Error.

2207 on "=" composing, but that doesn't quite work -- we want the "="

2227 * a-convec.ads, a-convec.adb: Use tampering check machinery
2229 Disable all checking code when checks are suppressed.
2230 Simplify many of the operations. Implement "&" in terms of Append,
2231 rather than "by hand".
2232 Remove: function "=" (L, R : Elements_Array) return Boolean is
2233 abstract; so we can call the predefined "=" on Elements_Array.
2234 For "=" on Vectors: Previously, we returned True immediately if
2235 Left'Address = Right'Address. That seems like a non-optimization
2236 ("if X = X" is unusual), so removed that. Simplify by using
2237 slice comparison ("=" on Element_Array will automatically call
2238 "=" on the components, even if user defined).

2292 2015-10-16 Bob Duff <duff@adacore.com>

2399 If Typ is a generic formal incomplete type, look at the actual

3003 definition of a type coming from a limited_with, get to the full view
3004 if it is not in the main code unit.
3006 2015-06-01 Eric Botcazou <ebotcazou@adacore.com>
3008 * gcc-interface/utils.c (create_var_decl_1): If an assembler name is
3009 specified, let the target mangle it before settting.

3012 2015-06-01 Eric Botcazou <ebotcazou@adacore.com>
3014 * gcc-interface/lang-specs.h (TARGET_VXWORKS_RTP): Move substitution to
3015 before first -gnatez switch. Simplify and add trailing space.
3017 2015-06-01 Eric Botcazou <ebotcazou@adacore.com>
3019 * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Record_Type>: If the
3020 record has a parent field and a representation clause, make sure that
3021 it is properly aligned.

3031 * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Variable>: Deal with
3032 address clause on aliased object with unconstrained nominal subtype.

3036 template, be prepared for an empty array.
3037 (maybe_unconstrained_array): Likewise.

3047 * s-oscons-tmplt.c: Add explicit tests for Android alongside Linux.
3049 2015-05-30 Eric Botcazou <ebotcazou@adacore.com>
3051 * adaint.c: Test for __linux__ instead of linux and __sun__ instead

3068 deal with the subtraction of a "negative" value in an unsigned type.
3070 2015-05-28 Eric Botcazou <ebotcazou@adacore.com>
3072 * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Subprogram_Type>: Do
3073 not error out on a return type which has a size that overflows if the
3074 return is done by invisible reference.
3076 2015-05-28 Eric Botcazou <ebotcazou@adacore.com>
3078 * gcc-interface/utils.c (gnat_pushdecl): Reunify the handling of array
3079 and pointer types wrt DECL_ORIGINAL_TYPE and adjust left and right.
3081 2015-05-28 Eric Botcazou <ebotcazou@adacore.com>
3083 * gcc-interface/gigi.h (gnat_stabilize_reference): Adjust.
3084 (rewrite_fn): Remove third parameter.
3085 (type_is_padding_self_referential): New inline predicate.
3086 (return_type_with_variable_size_p): Likewise.
3087 * gcc-interface/decl.c (allocatable_size_p): More around.
3088 (cannot_be_superflat_p): Rename into...
3089 (cannot_be_superflat ): ...this.
3090 (initial_value_needs_conversion): New predicate.
3091 (gnat_to_gnu_entity): Invoke type_is_padding_self_referential,
3092 initial_value_needs_conversion and adjust to above renaming.
3093 For a renaming, force the materialization if the inner expression
3094 is compound. Adjust calls to elaborate_reference and build a
3095 compound expression if needed.
3096 (struct er_dat): Add N field.
3097 (elaborate_reference_1): Remove N parameter and adjust.
3098 (elaborate_reference): Add INIT parameter and pass it in the call to
3099 gnat_rewrite_reference. Adjust initial expression.
3100 * gcc-interface/trans.c (Call_to_gnu): Treat renamings the same way as
3101 regular object declarations when it comes to creating a temporary.
3102 Adjust call to gnat_stabilize_reference and build a compound expression
3103 if needed. Invoke return_type_with_variable_size_p.
3104 (gnat_to_gnu): Invoke type_is_padding_self_referential. In case #4,
3105 return a call to a function unmodified if it returns with variable size
3106 and is also the initial expression in an object declaration.
3107 * gcc-interface/utils2.c (build_binary_op) <INIT_EXPR>: Use the RHS'
3108 type if it is a call to a function that returns with variable size.
3109 (build_unary_op): Invoke type_is_padding_self_referential.

3116 2015-05-28 Ed Schonberg <schonberg@adacore.com>
3118 * sem_ch3.adb (Is_Visible_Component): Component is visible
3119 in a derived type if inherited through an ancestor that has a
3120 partial view of the original type holding the component, if the
3121 full view of that original type is in scope.
3122 * sem_util.ads (Get_Body_From_Stub): Works for all kinds of stubs.
3124 2015-05-28 Bob Duff <duff@adacore.com>
3126 * sem_util.adb (Requires_Transient_Scope): For definite untagged
3127 subtypes, we should never have to use the secondary stack. This moves
3128 toward that goal. But there are still cases that don't work.
3129 Here, we move the check for Is_Definite first, but add a
3130 special-purpose check for Has_Discrim_Dep_Array.
3132 2015-05-28 Bob Duff <duff@adacore.com>
3134 * sem_util.adb (Requires_Transient_Scope): Avoid returning
3135 function results on the secondary stack in so many cases.
3137 2015-05-28 Ed Schonberg <schonberg@adacore.com>
3139 * sem_util.adb (Wrong_Type): In any instance, do not emit error
3140 if type of expression is the partial view of the expected type.
3142 2015-05-28 Ed Schonberg <schonberg@adacore.com>
3144 * sem_res.adb (Resolve_Actuals): a) The replacement of formal
3145 names in named associations only needs to be done within an
3146 instance, on a call to a primitive of a formal derived type,
3147 where the actual subprogram may have different formal names than
3148 those of the primitive operation of the formal type.
3149 b) Defaulted parameters must be taken into account when obtaining
3150 the names of the formals of the actual subprogram being called.
3152 2015-05-28 Robert Dewar <dewar@adacore.com>
3154 * sem_ch13.adb, sem_disp.ads: Minor reformatting.
3156 2015-05-28 Ed Schonberg <schonberg@adacore.com>
3158 * sem_util.adb (Set_Debug_Info_Needed): For a private type
3159 whose full view is itself a derived private type, set flag on
3160 underlying full view as well, for proper gdb display.
3162 2015-05-28 Bob Duff <duff@adacore.com>
3164 * exp_tss.ads: Minor comment fix.
3165 * exp_ch3.adb (Build_Array_Init_Proc, Build_Record_Init_Proc):
3166 Inline init_procs when the type has controlled parts. Remove
3167 obsolete comments about those init_procs -- init_procs for
3168 such types are no longer complex. A typical init_proc just
3169 initializes the 'Tag field, and calls the parent init_proc
3170 (e.g. for Limited_Controlled), which calls the grandparent
3171 (for Root_Controlled), which does nothing. This all boils down
3172 to one instruction when inlined.
3173 * exp_ch7.adb (Create_Finalizer): Inline the finalizer.
3175 2015-05-28 Ed Schonberg <schonberg@adacore.com>
3177 * sem_ch4.adb (Analyze_Selected_Component): If the type to use
3178 is a derived type and is a generic actual, the selected component
3179 appears within an instance body, and the check over the type
3180 has failed, examine ancestor types for the desired component.
3181 (Find_Component_In_Instance): If record type is a derived type,
3182 examine all ancestors in order to locate desired component.
3184 2015-05-27 H.J. Lu <hongjiu.lu@intel.com>
3186 * gcc-interface/Makefile.in (TOOLS_LIBS): Add @NO_PIE_FLAG@.
3188 2015-05-27 Eric Botcazou <ebotcazou@adacore.com>
3190 * gcc-interface/trans.c (elaborate_all_entities): Do not elaborate an
3191 incomplete type coming from a limited_with and whose non-limited view
3192 comes from the main unit.
3194 2015-05-27 Eric Botcazou <ebotcazou@adacore.com>
3196 * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Variable>: Move down
3197 code applying atomic checks to the object.
3199 2015-05-27 Robert Dewar <dewar@adacore.com>
3201 * sem_aux.adb: Minor rewording.
3203 2015-05-27 Bob Duff <duff@adacore.com>
3205 * exp_prag.adb (Expand_Pragma_Abort_Defer): Make
3206 pragma Abort_Defer do nothing if Abort_Allowed is False.
3208 2015-05-27 Arnaud Charlet <charlet@adacore.com>
3210 * exp_ch9.adb, sem_util.adb, sem_util.ads, s-stposu.adb, s-spsufi.ads,
3211 sem_elab.ads, g-comlin.ads, errout.ads, exp_ch6.adb, sem_ch4.adb,
3212 opt.ads, s-bignum.adb, output.ads, sem_ch13.adb, erroutc.ads,
3213 sem_disp.ads, exp_ch3.adb: Minor fixes of duplicate words in comments.
3215 2015-05-27 Doug Rupp <rupp@adacore.com>
3217 * adaint.c (__gnat_tmp_name) [vxworks]: Robustify and use for rtp as
3220 2015-05-27 Pierre-Marie de Rodat <derodat@adacore.com>
3222 * par_sco.adb (Process_Decision): Store sloc to
3223 condition/pragmas SCOs associations into a temporary table before
3224 moving them to the SCO_Raw_Hash_Table so that we can back them
3225 out just like we do for SCO entries that are simple decisions
3226 in an expression context.
3228 2015-05-27 Ed Schonberg <schonberg@adacore.com>
3230 * sem_ch6.adb (Process_Formals): A non-private formal type that
3231 is a limited view does not have a list of private dependents.
3233 2015-05-27 Ed Schonberg <schonberg@adacore.com>
3235 * exp_ch5.adb (Expand_N_Case_Statement): If the expression in
3236 the case statement is a compile-time known value, we look for a
3237 corresponding alternative to optimize the case statement into a
3238 single case. If the type has a static predicate and the expression
3239 does not satisfy the predicate, there is no legal alternative and
3240 this optimization is not applicable. Excecution is erroneous,
3241 or else if assertions are enabled, an exception will be raised
3242 earlier, at the point the expression is elaborated.
3244 2015-05-27 Robert Dewar <dewar@adacore.com>
3246 * sem_elab.adb (Check_Internal_Call_Continue): Suppress
3247 warning on Finalize, Adjust, or Initialize if type involved has
3250 2015-05-27 Ed Schonberg <schonberg@adacore.com>
3252 * sem_aux.adb, sem_aux.ads (First_Discriminant): Return empty when
3253 applied to a type with no known discriminants.
3255 2015-05-26 Robert Dewar <dewar@adacore.com>
3257 * errout.ads, sem_ch4.adb, sem_ch6.adb: Minor reformatting.
3259 2015-05-26 Bob Duff <duff@adacore.com>
3261 * sem_elab.adb (Check_A_Call): In the case where we're
3262 calling something in an instance of a generic package that is
3263 within this same unit (as the call), make sure we treat it
3264 as a call to an entity within the same unit. That is, call
3265 Check_Internal_Call, rather than putting "Elaborate_All(X)"
3266 on X, which would necessarily result in an elaboration cycle in
3267 static-elaboration mode.
3269 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
3271 * freeze.ads (Is_Atomic_VFA_Aggregate): Adjust profile.
3272 * freeze.adb (Is_Atomic_VFA_Aggregate): Change Entity
3273 parameter into Node parameter and remove Type parameter.
3274 Look at Is_Atomic_Or_VFA both on the type and on the object.
3275 (Freeze_Entity): Adjust call to Is_Atomic_VFA_Aggregate.
3276 * exp_aggr.adb (Expand_Record_Aggregate): Likewise.
3277 (Process_Atomic_Independent_Shared_Volatile): Remove code
3278 propagating Atomic or VFA from object to locally-defined type.
3280 2015-05-26 Bob Duff <duff@adacore.com>
3282 * exp_ch7.adb: Minor comment fix.
3284 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
3286 * gcc-interface/trans.c (Attribute_to_gnu) <Attr_Min/Attr_Max>: Do not
3287 bother about NaN's if Machine_Overflows is true.
3289 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
3291 * gcc-interface/trans.c (gnat_to_gnu) <N_Object_Declaration>: Really
3292 force evaluation of the expression, if any, when the object has its
3293 elaboration delayed. Do not create a variable at global level.
3295 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
3297 * gcc-interface/trans.c (Attribute_to_gnu) <Attr_Machine>: Do not apply
3298 extra-precision trick to literals. Build SAVE_EXPR manually.
3300 * gcc-interface/misc.c (enumerate_modes): Add bypass for x86/x86-64.

3313 (elaborate_reference): Likewise.
3314 (gnat_to_gnu_entity): Call elaborate_reference to elaborate renamings
3315 and simplify associated code. Set const_flag to true consistently in
3316 conjunction with used_by_ref.
3317 * gcc-interface/trans.c (Identifier_to_gnu): Always replace renaming
3318 pointers by renamed objects.
3319 (outer_atomic_access_required_p): Deal with renamings.

3331 (gnat_stabilize_reference_1): Adjust.
3332 (gnat_stabilize_reference): Call gnat_stabilize_reference_1 through
3333 gnat_rewrite_reference and move bulk of code to...
3334 (gnat_rewrite_reference): ...here. New global function.
3335 (gnat_constant_reference_p): Delete.
3337 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
3339 * gcc-interface/gigi.h (gnat_stabilize_reference): Adjust prototype.
3340 * gcc-interface/decl.c (gnat_to_gnu_entity): Do not rely on const_flag
3341 to detect constant renamings. Be prepared for specific pattern of
3342 renamed object based on function calls. Create a constant object
3343 for the renaming of a NULL_EXPR or of a CONSTRUCTOR. Adjust calls
3344 to gnat_stabilize_reference and tidy up. Remove redundant tests.
3345 (elaborate_expression_1): Remove obsolete test and tidy up.
3346 * gcc-interface/trans.c (Call_to_gnu): Do not stabilize In/Out or Out
3347 parameters passed by reference.
3348 (gnat_to_gnu) <N_Selected_Component>: Remove redundant protection again
3350 Use gnat_protect_expr instead of gnat_stabilize_reference for general
3351 protection against side-effects.

3353 (gnat_save_expr): Invoke it.

3363 * sinfo.ads: Minor reformatting.
3364 * sem_aux.ads: Clarify use of First_Discriminant.
3365 * sem_ch4.adb (Analyze_Explicit_Dereference): The use of a limited
3366 view is replaced with the non-limited view in an instance body,
3367 where the enclosing unit must have a regular with_clause on the
3369 * sem_ch12.adb (Install_Body): Freeze instantation after its
3370 body. Remove useless freeze nodes for incomplete actuals to
3371 prevent multiple generation of internal operations.
3372 (Instantiate_Package_Body): Set sloc of body appropriately when
3373 there are incomplete actuals and the instance body is placed in
3374 the body of the enclosing unit.
3375 * errout.ads: Consistent punctuation, better alignment and trivial
3377 * err_vars.ads: Fix typo.
3379 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
3381 * sem_ch8.adb (Analyze_Object_Renaming): Lift restriction on
3382 components of Volatile_Full_Access objects.

3386 * sem_ch6.adb (Is_Non_Overriding_Operation,
3387 Get_Generic_Parent_Type): Handle properly the case of a derived
3388 scalar type by using the first subtype rather than its generated
3389 anonymous base type.
3391 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
3393 * einfo.adb (Write_Field17_Name): Move E_Incomplete_Subtype
3395 (Write_Field19_Name): ...here.
3397 2015-05-26 Ed Schonberg <schonberg@adacore.com>
3399 * sem_ch13.adb: sem_ch13.adb (Add_Predicates): Undo analysis
3400 of original expression in ASIS mode: does not solve the ASIS
3401 problem of a usable type information, and crashes the back-end
3402 when performing type annotations.
3404 2015-05-26 Robert Dewar <dewar@adacore.com>
3406 * sem_disp.adb (Inherited_Subprograms): Add One_Only parameter.

3414 exp_ch3.adb: Minor reformatting.
3416 2015-05-26 Bob Duff <duff@adacore.com>
3418 * treepr.adb: Minor improvement to debugging routines (pp, pn)
3419 robustness. Rearrange the code so passing a nonexistent Node_Id
3420 prints "No such node" rather than crashing, and causing gdb to
3421 generate confusing messages.
3423 2015-05-26 Gary Dismukes <dismukes@adacore.com>
3425 * sem_util.adb: Minor typo fix.

3945 the aspect will be inserted at the freeze point of the type,
3946 which may be in the private part and not directly visible,
3947 but the aspect makes the operation available to a client.

4157 2015-05-22 Ed Schonberg <schonberg@adacore.com>
4159 * sem_res.adb (Resolve_Actuals): If the call is to an overridden
4160 operation, replace the names of the actuals in named associations
4161 with the names of the actuals of the subprogram that is eventually
4162 executed. The names of the formals and the defaults can differ
4163 between the two operations when they are operations of a formal

4221 * snames.ads-tmpl: New names referenced by exp_ch5.adb.
4222 * exp_ch5.adb: Speed up "for ... of" loops for predefined containers.
4223 Instead of doing literally what the RM calls for, we do something
4224 equivalent that avoids expensive operations inside the loop. If the
4225 container package has appropriate Next, Pseudo_Reference,
4226 Element_Access, Get_Element_Access declarations, we invoke the
4228 * snames.ads-tmpl: Note speed improvement.

4262 change that deals with the fact that most of the special coding for
4263 Atomic should also apply to the case of Volatile_Full_Access.
4264 A new attribute Is_Atomic_Or_VFA is introduced, and many of the
4265 references to Is_Atomic now use this new attribute.

4324 * einfo.ads, einfo.adb (Incomplete_Actuals): New attribute of
4325 package instantiations. Holds the list of actuals in the instance
4326 that are incomplete types, to determine where the corresponding

4336 freeze nodes for actuals.
4337 (Install_Body): In the presence of actuals that incomplete types
4338 from a limited view, the instance body cannot be placed after
4339 the declaration because full views have not been seen yet. Any
4340 use of the non-limited views in the instance body requires
4341 the presence of a regular with_clause in the enclosing unit,
4342 and will fail if this with_clause is missing. We place the
4343 instance body at the beginning of the enclosing body, which is
4344 the unit being compiled, and ensure that freeze nodes for the
4345 full views of the incomplete types appear before the instance.

7807 ttypes values and the GNAT tree nodes for the standard floating
7809 * set_targ.adb (Long_Double_Index): The index at which "long
7810 double" gets registered in the FPT_Mode_Table. This is useful to
7811 know whether we have a "long double" available at all and get at

7824 so C_Type_For can operate regardless of -gnateT. Do it
7825 early so we can query it for the floating point sizes, via
7826 FPT_Mode_Index_For. Initialize Float_Size, Double_Size and
7827 Long_Double_Size from the FPT_Mode_Table, as cstand will do.
7828 * cstand.adb (Create_Float_Types): Use C_Type_For to determine
7829 which C type should be used as the basis for the construction
7830 of the Standard Ada floating point types.

7847 function wrapper may be a homonym of another local declaration.
7848 * sem_ch8.adb (Analyze_Subprogram_Renaming): In GNATprove mode,
7849 build function and operator wrappers after the actual subprogram
7850 has been resolved, and replace the standard renaming declaration
7851 with the declaration of wrapper.
7852 * sem_ch12.ads (Build_Function_Wrapper, Build_Operator_Wraooer):
7853 make public for use elsewhere.
7854 * sem_ch12.adb (Build_Function_Wrapper, Build_Operator_Wraooer):
