+ * Makefile.rtl (GNATLIB_SHARED): Revert disablement for arm-qnx.

+2022-06-01 Eric Botcazou <ebotcazou@adacore.com>
+
+ * sem_util.adb
+ (Returns_On_Secondary_Stack.Caller_Known_Size_Record): Directly
+ check the dependence on discriminants for the variant part, if

+ earlier, do not initialize Iface_Formal, use No idiom and tweaks

+
+ * exp_ch3.ads: Replace visible Build_Discr_Checking_Funcs (which
+ did not need to be visible - it was not referenced outside this
+ package) with Build_Or_Copy_Discr_Checking_Funcs.
+ * exp_ch3.adb: Refactor existing code into 3 procedures -
+ Build_Discr_Checking_Funcs, Copy_Discr_Checking_Funcs, and
+ Build_Or_Copy_Discr_Checking_Funcs. This refactoring is intended
+ to be semantics-preserving.
+ * exp_ch4.adb (Expand_N_Selected_Component): Detect case where a
+ call should be generated to the Discriminant_Checking_Func for
+ the component in question, but that subprogram does not yet
+ exist.
+ * sem_ch13.adb (Freeze_Entity_Checks): Immediately before
+ calling Build_Predicate_Function, add a call to
+ Exp_Ch3.Build_Or_Copy_Discr_Checking_Funcs in order to ensure
+ that Discriminant_Checking_Func attributes are already set when
+ Build_Predicate_Function is called.
+ * sem_ch6.adb (Analyze_Expression_Function): If the expression
+ of a static expression function has been transformed into an
+ N_Raise_xxx_Error node, then we need to copy the original
+ expression in order to check the requirement that the expression
+ must be a potentially static expression. We also want to set
+ aside a copy the untransformed expression for later use in
+ checking calls to the expression function via
+ Inline_Static_Function_Call. So introduce a new function,
+ Make_Expr_Copy, for use in these situations.
+ * sem_res.adb (Preanalyze_And_Resolve): When analyzing certain
+ expressions (e.g., a default parameter expression in a
+ subprogram declaration) we want to suppress checks. However, we
+ do not want to suppress checks for the expression of an
+ expression function.

+
+ * exp_ch5.adb (Expand_Iterator_Loop_Over_Container): For each
+ subprogram found, assert that the variable is Empty, so we can
+ detect bugs where we find two or more things with the same name.
+ Without this patch, that bug would happen when we add the new
+ Next procedure. For Step, make sure we pick the right one, by
+ checking name and number of parameters. For Get_Element_Access,
+ check that we're picking a function. That's not really
+ necessary, because there is no procedure with that name, but it
+ seems cleaner this way.
+ * rtsfind.ads: Minor comment improvement. It seems kind of odd
+ to say "under no circumstances", and then immediately contradict
+ that with "The one exception is...".
