[COMMITTED] ada: Fix internal error on Big_Integer conversion ghost instance
Checks
Commit Message
From: Eric Botcazou <ebotcazou@adacore.com>
The problem is that the ghost mode of the instance is used to analyze the
parent of the generic body, whose own ghost mode has nothing to do with it.
gcc/ada/
* sem_ch12.adb (Instantiate_Package_Body): Set the ghost mode to
that of the instance only after loading the generic's parent.
(Instantiate_Subprogram_Body): Likewise.
Tested on x86_64-pc-linux-gnu, committed on master.
