[Ada] Missing error on illegal access to discriminant
The compiler does not report an error on the illegal access to a renamed
discriminant when the actual object is a parameter of a subprogram.
2018-05-24 Javier Miranda <miranda@adacore.com>
gcc/ada/
* sem_ch3.adb (Is_Visible_Component): For untagged types add missing
check for renamed discriminants.
* sem_ch4.adb (Analyze_Overloaded_Selected_Component,
Analyze_Selected_Component, Check_Misspelled_Selector): For calls to
Is_Visible_Component pass the associated selector node to allow
checking renamed discriminants on untagged types.
gcc/testsuite/
* gnat.dg/discr52.adb: New testcase.
