- type is known to be constrained (it is within a generic spec,

-
- * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
- to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
- We need to analyze it as part of analyzing the block, so that if the
- call to Element that initializes Elmt_Decl returns on the secondary
- stack, the block will ss_mark/ss_release. This block is inside the
- loop; we don't want to leak memory until the loop exits. The purpose
- of analyzing Elmt_Decl first was to catch the error of modifying it,
- which is illegal because it's a loop parameter. The above causes us to
- miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
- it on the Element entity, so we end up with an E_Variable node with the
- flag set.
- * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.

- * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
- a package body that is a compilation unit may contain blocks that
- declare local subprograms. In Subprogram_Unnesting Mode such
- subprograms must be handled as nested inside the (implicit) elaboration
- procedure that executes that statement part. To handle properly uplevel
- references we construct that subprogram explicitly, to contain blocks
- and inner subprograms, The statement part of the compilation unit
- becomes a call to this subprogram. This is only done if blocks are

-
- * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
- value when converting a float value to a fixed-point value. This is
- required for CCG because it handles fixed-point types by means of

- been relocated, set first_named pointer in original node as well.
-
-2018-05-28 Ed Schonberg <schonberg@adacore.com>
-
- * exp_aggr.adb (Flatten): Copy tree of expression in a component
- association with a range or a set of discrete choices, rather than

-
- * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression

-2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
-
- * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
- (SS_Allocate_Dynamic): New routine. The allocation logic is now split
- into three distring cases rather than in one loop which attempts to
- handle all three cases. This rewrite eliminates an issue where the last
- frame of the stack cannot be freed, thus causing the memory range of a
- new frame to approach the overflow point of the memory index type.
- Since the overflow is logically treated as a
- too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
- (SS_Allocate_Static): New routine. The routine factorizes the static
- secondary stack-related code from the former SS_Allocate.

- is the proper body of a subunit, the cloned body must be inserted in
- the declarative list that contains the stub.
-
-2018-05-25 Justin Squirek <squirek@adacore.com>
-
- * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to

- Minor reformatting.
-
-2018-05-25 Ed Schonberg <schonberg@adacore.com>
-
- * sem_ch12.adb (Instance_Exists): New function, subsidiary of
- Validate_Derived_Type_Instance, to verify that all interfaces
- implemented by the formal type are also implemented by the actual. The
- verification is complicated when an interface of the formal is declared
- in a generic unit and the actual is declared in an instance of it.
- There is currently no mechanism to relate an interface declared within
- a generic to the corresponding interface in an instance, so we must
- traverse the list of interfaces of the actual, looking for a name
- match, and verifying that that interface is declared in an instance.
-
-2018-05-25 Piotr Trojanek <trojanek@adacore.com>
-
- * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra

+
+ * sem_ch12.adb (Instance_Exists): New function, subsidiary of

+ verification is complicated when an interface of the formal is declared
+ in a generic unit and the actual is declared in an instance of it.
+ There is currently no mechanism to relate an interface declared within
+ a generic to the corresponding interface in an instance, so we must
