From: Piotr Trojanek <[email protected]>
In lock-free protected subprograms we don't allow goto statements;
likewise, we now reject conditional goto statements.
This fix only affects semantic checking mode with switch -gnatc.
In ordinary compilation we already rejected conditional goto after
it was expanded into ordinary goto.
gcc/ada/
* sem_ch9.adb (Allows_Lock_Free_Implementation): Reject
conditional goto statements.
Tested on x86_64-pc-linux-gnu, committed on master.
