Checks
Commit Message
From: Yannick Moy <moy@adacore.com>
SPARK_Mode On can only be used on library-level entities.
Improve the error message here.
gcc/ada/
* errout.ads: Add explain code.
* sem_prag.adb (Check_Library_Level_Entity): Refine error message
and add explain code.
Tested on x86_64-pc-linux-gnu, committed on master.
