-
- * sem_util.ads (Interval_Lists): A new visible package. This
- package is visible because it is also intended for eventual use
- in Sem_Eval.Subtypes_Statically_Compatible when that function is
- someday upgraded to handle static predicates correctly. This
- new package doesn't really need to be visible for now, but it
- still seems like a good idea.
- * sem_util.adb (Gather_Components): Implement AI12-0086 via the
- following strategy. The existing code knows how to take a static
- discriminant value and identify the corresponding variant; in
- the newly-permitted case of a non-static value of a static
- subtype, we arbitrarily select a value of the subtype and find
- the corresponding variant using the existing code. Subsequently,
- we check that every other value of the discriminant's subtype
- corresponds to the same variant; this is done using the newly
- introduced Interval_Lists package.
- (Interval_Lists): Provide a body for the new package.
-
-2019-09-18 Javier Miranda <miranda@adacore.com>
-
- * exp_ch4.adb (Expand_N_Op_Eq): The frontend assumes that we can
- do a bit-for-bit comparison of two access to protected
- subprogram pointers. However, there are two reasons why we may
- not be able to do that: (1) there may be padding bits for
- alignment before the access to subprogram, and (2) the access to
- subprogram itself may not be compared bit-for- bit because the
- activation record part is undefined: two pointers are equal iff
- the subprogram addresses are equal. This patch fixes it by
- forcing a field-by-field comparison.
- * bindgen.adb (Gen_Adainit): The type No_Param_Proc is defined
- in the library as having Favor_Top_Level, but when we create an
- object of that type in the binder file we don't have that
- pragma, so the types are different. This patch fixes this issue.
- * libgnarl/s-interr.adb, libgnarl/s-interr__hwint.adb,
- libgnarl/s-interr__sigaction.adb, libgnarl/s-interr__vxworks.adb
- (Is_Registered): This routine erroneously assumes that the
- access to protected subprogram is two addresses. We need to
- create the same record that the compiler makes to ensure that
- any padding is the same. Then we have to look at just the first
- word of the access to subprogram. This patch fixes this issue.

+ * sem_util.adb (Gather_Components): Implement AI12-0086 via the

+ the newly-permitted case of a non-static value of a static
+ subtype, we arbitrarily select a value of the subtype and find
+ the corresponding variant using the existing code. Subsequently,
+ we check that every other value of the discriminant's subtype
+ corresponds to the same variant; this is done using the newly

+2019-09-18 Javier Miranda <miranda@adacore.com>
+
+ * exp_ch4.adb (Expand_N_Op_Eq): The frontend assumes that we can
+ do a bit-for-bit comparison of two access to protected
+ subprogram pointers. However, there are two reasons why we may
+ not be able to do that: (1) there may be padding bits for
+ alignment before the access to subprogram, and (2) the access to
+ subprogram itself may not be compared bit-for- bit because the
+ activation record part is undefined: two pointers are equal iff
+ the subprogram addresses are equal. This patch fixes it by
+ forcing a field-by-field comparison.
+ * bindgen.adb (Gen_Adainit): The type No_Param_Proc is defined
+ in the library as having Favor_Top_Level, but when we create an
+ object of that type in the binder file we don't have that
+ pragma, so the types are different. This patch fixes this issue.
+ * libgnarl/s-interr.adb, libgnarl/s-interr__hwint.adb,
+ libgnarl/s-interr__sigaction.adb, libgnarl/s-interr__vxworks.adb
+ (Is_Registered): This routine erroneously assumes that the
+ access to protected subprogram is two addresses. We need to
+ create the same record that the compiler makes to ensure that
+ any padding is the same. Then we have to look at just the first
+ word of the access to subprogram. This patch fixes this issue.
