* exp_ch4.adb (Expand_N_Type_Conversion): Remove special processing
for conversion of a Float_Type'Truncation to integer.
* exp_attr.adb (Is_Inline_Floating_Point_Attribute): New function to
check if a node is an attribute that can be handled directly by the
back end.
(Expand_N_Attribute_Reference): Suppress expansion of floating-point
attributes that can be handled directly by the back end.
(Expand_N_Attribute_Reference, case 'Access and 'Unchecked_Access):
use new predicate Is_Access_Protected_Subprogram_Type.
(Expand_N_Attribute_Reference, case 'Write): The reference is legal for
and Unchecked_Union if it is generated as part of the default Output
procedure for a type with default discriminants.
(Expand_N_Attribute_Reference): Avoid the expansion of dispatching calls
if we are compiling under restriction No_Dispatching_Calls.
(Constrained): Use Underlying_Type, in case the type is private without
discriminants, but the full type has discriminants.
(Expand_N_Attribute_Reference): Replace call to Get_Access_Level by
call to Build_Get_Access_Level.
(Expand_N_Attribute_Reference): The use of 'Address with class-wide
interface objects requires a call to the run-time subprogram that
returns the base address of the object.
(Valid_Conversion): Improve error message on illegal attempt to store
an anonymous access to subprogram value into a record component.
* sem_res.adb (Resolve_Equality_Op): Detect ambiguity for "X'Access =
null".
(Simplify_Type_Conversion): New procedure that performs simplification
of Int_Type (Float_Type'Truncation (X)).
(Resolve_Type_Conversion): Call above procedure after resolving operand
and before performing checks. This replaces the existing ineffective
code in Exp_Ch4.
(Set_String_Literal_Subtype): When creating the internal static lower
bound subtype for a string literal, use a newly created copy of the
subtree representing the lower bound.
(Resolve_Call): Exclude build-in-place function calls from transient
scope treatment. Update comments to describe this exception.
(Resolve_Equality_Op): In case of dispatching call check violation of
restriction No_Dispatching_Calls.
(Resolve_Call): If the call returns an array, the context imposes the
component type of the array, and the function has one non-defaulted
parameter, rewrite the call as the indexing of a call with a single
parameter, to handle an Ada 2005 syntactic ambiguity for calls written
in prefix form.
(Resolve_Actuals): If an actual is an allocator for an access parameter,
the master of the created object is the innermost enclosing statement.
(Remove_Conversions): For a binary operator, check if type of second
formal is numeric, to check if an abstract interpretation is present
in the case of exponentiation as well.
