From 53ed0028adacb4e9c033b236805ae409823178ab Mon Sep 17 00:00:00 2001 From: Piotr Trojanek Date: Wed, 15 Feb 2023 21:20:42 +0100 Subject: ada: Suppress warning about Subprogram_Variant failing at run time Warning about check failing at run time is likely spurious for mutually recursive subprograms with multiple variant clauses. These will be non-trivial to detect, so we simply suppress the warning altogether for all subprogram variants. gcc/ada/ * exp_prag.adb (Expand_Pragma_Check): Suppress warning for checks of subprogram variants. --- gcc/ada/exp_prag.adb | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'gcc') diff --git a/gcc/ada/exp_prag.adb b/gcc/ada/exp_prag.adb index ceb27848..c6b3bed 100644 --- a/gcc/ada/exp_prag.adb +++ b/gcc/ada/exp_prag.adb @@ -564,6 +564,13 @@ package body Exp_Prag is then null; + -- For Subprogram_Variant suppress the warning altogether, because + -- for mutually recursive subprograms with multiple variant clauses + -- some of the clauses might have expressions that are only meant for + -- verification and would always fail when executed. + + elsif Nam = Name_Subprogram_Variant then + null; elsif Nam = Name_Assert then Error_Msg_N ("?.a?assertion will fail at run time", N); else -- cgit v1.1
