currently, aarch64 LEGITIMIZE_ADDRESS_P hook will reject all "reg + offset"
address given "offset" is beyond supported range.
while this may be too strict. we should honor the "strict_p" parameter in the
hook. before reload, we accept all offset if it's a frame access, because the
offset may change during later register elimination.
the early reject of "reg + offset" may cause extra registers created, and if
that register live range is across function invoking then callee saved reg
needed, thus introduce extra reg save/restore also.
give a simple example as:
int
test15 (void)
{
unsigned char a[480];
initialize_array (a, 480);
if (a[0] == 0x10)
return 1;
return 0;
}

on aarch64, we are using load register pair post-writeback instruction in
epilogue.
for example, for the following instruction:
ldp, x0, x1, [sp], #16
what it's doing is:
x0 <- MEM(sp + 0)
x1 <- MEM(sp + 8)
sp < sp + 16
while there is a glitch in our loadwb_pair* pattern, the restore of the
first reg should always be with offset zero.

is a subtype with dynamic predicates, or a non-static subtype
with predicates.

expression if subtype has a dynamic predicate.
(Constrain_Index): Reject subtype indication if subtype mark
has predicates.

(Make_Index): If index is a subtype indication, itype inhereits
predicate flags for subsequent testing.

procedure Check_Predicate_Use, to reject illegal uses of domains
of iteration that have dynamic predicates.

* sem_ch6.adb (Same_Generic_Actual): Make function symmetric,
because either type may be a subtype of the other.

* sem_dim.adb (Process_Minus, Process_Divide): Label dimension
expression with standard operator and type, for pretty-printing
use, when in ASIS_Mode. When generating code dimensional analysis
is not involved and dimension expressions are handled statically,
and other operators are resolved in the usual way.

* sem_ch3.adb (Build_Derived_Record_Type): Remove setting of
Parent_Subtype in ASIS mode, leads to several failures.
* sem_ch4.adb (Analyze_Selected_Component): In an instance,
if the prefix is a type extension, check whether component is
declared in the parent type, possibly in a parent unit. Needed
in ASIS mode when Parent_Subtype is not set.

* sem_ch13.adb (Analyze_Aspect_Specifications, case Aspect_Import):
Set Is_Imported flag at once, to simplify subsequent legality
checks. Reject the aspect on an object whose declaration has an
explicit initial value.
* sem_prag.adb (Process_Import_Or_Interface): Use original node
to check legality of an initial value for an imported entity.
Set Is_Imported flag in case of error to prevent cascaded errors.
Do not set the Is_Imported flag if the pragma comes from an
aspect, because it is already done when analyzing the aspect.

type of an array of pointers when the designated type is
class-wide and its root type is the record being currently frozen.

* sem_ch5.adb (Analyze_Iterator_Specification): Preserve Ekind
of renaming declaration created for domain of iteration.
* sem_aggr.adb (Resolve_Array_Aggregate): Better placement
for error messages on aggregates whose index subtypes have
predicates. The new placement avoids posting messages on previous
subtype declarations rather than on the aggregate itself.
* sem_disp.adb (Is_Inherited_Public_Operation): New predicate for
Add_Dispatching_Operation, to handle properly the overriding of
the predefined operations on controlled types, when the partial
view of a type is not visibly controlled.
2014-08-01 Ben Brosgol <brosgol@adacore.com>

appendix.
