2015-05-28 Ed Schonberg <schonberg@adacore.com>
* sem_ch3.adb (Is_Visible_Component): Component is visible
in a derived type if inherited through an ancestor that has a
partial view of the original type holding the component, if the
full view of that original type is in scope.
* sem_util.ads (Get_Body_From_Stub): Works for all kinds of stubs.
2015-05-28 Bob Duff <duff@adacore.com>
* sem_util.adb (Requires_Transient_Scope): For definite untagged
subtypes, we should never have to use the secondary stack. This moves
toward that goal. But there are still cases that don't work.
Here, we move the check for Is_Definite first, but add a
special-purpose check for Has_Discrim_Dep_Array.
2015-05-28 Bob Duff <duff@adacore.com>
* sem_util.adb (Requires_Transient_Scope): Avoid returning
function results on the secondary stack in so many cases.
2015-05-28 Ed Schonberg <schonberg@adacore.com>
* sem_util.adb (Wrong_Type): In any instance, do not emit error
if type of expression is the partial view of the expected type.
2015-05-28 Ed Schonberg <schonberg@adacore.com>
* sem_res.adb (Resolve_Actuals): a) The replacement of formal
names in named associations only needs to be done within an
instance, on a call to a primitive of a formal derived type,
where the actual subprogram may have different formal names than
those of the primitive operation of the formal type.
b) Defaulted parameters must be taken into account when obtaining
the names of the formals of the actual subprogram being called.

* sem_ch13.adb, sem_disp.ads: Minor reformatting.
2015-05-28 Ed Schonberg <schonberg@adacore.com>
* sem_util.adb (Set_Debug_Info_Needed): For a private type
whose full view is itself a derived private type, set flag on
underlying full view as well, for proper gdb display.
2015-05-28 Bob Duff <duff@adacore.com>
* exp_tss.ads: Minor comment fix.
* exp_ch3.adb (Build_Array_Init_Proc, Build_Record_Init_Proc):
Inline init_procs when the type has controlled parts. Remove
obsolete comments about those init_procs -- init_procs for
such types are no longer complex. A typical init_proc just
initializes the 'Tag field, and calls the parent init_proc
(e.g. for Limited_Controlled), which calls the grandparent
(for Root_Controlled), which does nothing. This all boils down
to one instruction when inlined.
* exp_ch7.adb (Create_Finalizer): Inline the finalizer.
2015-05-28 Ed Schonberg <schonberg@adacore.com>
* sem_ch4.adb (Analyze_Selected_Component): If the type to use
is a derived type and is a generic actual, the selected component
appears within an instance body, and the check over the type
has failed, examine ancestor types for the desired component.
(Find_Component_In_Instance): If record type is a derived type,
examine all ancestors in order to locate desired component.
2015-05-27 H.J. Lu <hongjiu.lu@intel.com>

2015-05-27 Eric Botcazou <ebotcazou@adacore.com>

incomplete type coming from a limited_with and whose non-limited view
comes from the main unit.
2015-05-27 Eric Botcazou <ebotcazou@adacore.com>
* gcc-interface/decl.c (gnat_to_gnu_entity) <E_Variable>: Move down
code applying atomic checks to the object.

2015-05-27 Bob Duff <duff@adacore.com>

pragma Abort_Defer do nothing if Abort_Allowed is False.

well as kernel.
2015-05-27 Pierre-Marie de Rodat <derodat@adacore.com>
* par_sco.adb (Process_Decision): Store sloc to
condition/pragmas SCOs associations into a temporary table before
moving them to the SCO_Raw_Hash_Table so that we can back them
out just like we do for SCO entries that are simple decisions
in an expression context.
2015-05-27 Ed Schonberg <schonberg@adacore.com>
* sem_ch6.adb (Process_Formals): A non-private formal type that
is a limited view does not have a list of private dependents.
2015-05-27 Ed Schonberg <schonberg@adacore.com>
* exp_ch5.adb (Expand_N_Case_Statement): If the expression in
the case statement is a compile-time known value, we look for a
corresponding alternative to optimize the case statement into a
single case. If the type has a static predicate and the expression
does not satisfy the predicate, there is no legal alternative and
this optimization is not applicable. Excecution is erroneous,
or else if assertions are enabled, an exception will be raised
earlier, at the point the expression is elaborated.
2015-05-27 Robert Dewar <dewar@adacore.com>
* sem_elab.adb (Check_Internal_Call_Continue): Suppress
warning on Finalize, Adjust, or Initialize if type involved has
Warnings_Off set.
2015-05-27 Ed Schonberg <schonberg@adacore.com>

applied to a type with no known discriminants.
2015-05-26 Robert Dewar <dewar@adacore.com>
* errout.ads, sem_ch4.adb, sem_ch6.adb: Minor reformatting.
2015-05-26 Bob Duff <duff@adacore.com>
* sem_elab.adb (Check_A_Call): In the case where we're
calling something in an instance of a generic package that is
within this same unit (as the call), make sure we treat it
as a call to an entity within the same unit. That is, call
Check_Internal_Call, rather than putting "Elaborate_All(X)"
on X, which would necessarily result in an elaboration cycle in
static-elaboration mode.
2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
* freeze.ads (Is_Atomic_VFA_Aggregate): Adjust profile.
* freeze.adb (Is_Atomic_VFA_Aggregate): Change Entity
parameter into Node parameter and remove Type parameter.
Look at Is_Atomic_Or_VFA both on the type and on the object.
(Freeze_Entity): Adjust call to Is_Atomic_VFA_Aggregate.
* exp_aggr.adb (Expand_Record_Aggregate): Likewise.
(Process_Atomic_Independent_Shared_Volatile): Remove code
propagating Atomic or VFA from object to locally-defined type.

elaboration delayed. Do not create a variable at global level.
2015-05-26 Eric Botcazou <ebotcazou@adacore.com>

extra-precision trick to literals. Build SAVE_EXPR manually.

change that deals with the fact that most of the special coding for
Atomic should also apply to the case of Volatile_Full_Access.

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

* sem_ch8.adb (Available_Subtype): Optimization in
Find_Selected_Component: when safe, use existing subtype of
array component, possibly discriminant-dependent, rather than
creating new subtype declaration for it. In this fashion different
occurrences of the component have the same subtype, rather than
just equivalent ones. Simplifies value tracing in GNATProve.

* set_targ.ads (C_Type_For): New function. Return the name of
a C type supported by the back-end and suitable as a basis to

ttypes values and the GNAT tree nodes for the standard floating
point types.
* set_targ.adb (Long_Double_Index): The index at which "long
double" gets registered in the FPT_Mode_Table. This is useful to

FPT_Mode_Table that designates the entry for a back-end type
suitable as a basis to construct the standard Ada floating point
type identified by the input T parameter.

so C_Type_For can operate regardless of -gnateT. Do it
early so we can query it for the floating point sizes, via
FPT_Mode_Index_For. Initialize Float_Size, Double_Size and
Long_Double_Size from the FPT_Mode_Table, as cstand will do.
