From: Justin Squirek <squirek@adacore.com> This patch fixes an error in the compiler whereby an assignment to an out formal (whose type requires a predicate check) can lead to spurious "value may be referenced before it has a value" warnings when the RHS is a qualified expression. gcc/ada/ * sem_warn.adb (Within_Postcondition): Add case to ignore references within generated predicate function calls. Tested on x86_64-pc-linux-gnu, committed on master. --- gcc/ada/sem_warn.adb | 10 ++++++++++ 1 file changed, 10 insertions(+)
