From: Yannick Moy <moy@adacore.com> GNATprove expects the frontend to position correctly range check flags, on expressions which might lead to a range check failure. This was missing on in-out parameters of calls. Now fixed. There is no impact on compilation. gcc/ada/ * sem_res.adb (Resolve_Actuals): Add range check flag. Tested on x86_64-pc-linux-gnu, committed on master. --- gcc/ada/sem_res.adb | 11 +++++++++++ 1 file changed, 11 insertions(+)
