--- Comment #4 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Eric Botcazou <ebotca...@gcc.gnu.org>: https://gcc.gnu.org/g:ac18ded230f1559f271f8d66121b2f16805f0b27 commit r12-744-gac18ded230f1559f271f8d66121b2f16805f0b27 Author: Bob Duff <d...@adacore.com> Date: Wed May 12 11:56:47 2021 +0200 Fix uninitialized variable in Atree.Size_In_Slots Size_In_Slots uses the Nkind to look up the size in a table indexed by Nkind. This patch fixes a couple of places where the Nkind is wrong (uninitialized or zeroed out) so Size_In_Slots cannot be used. gcc/ada/ PR ada/100564 * atree.adb (Change_Node): Do not call Zero_Slots on a Node_Id when the Nkind has not yet been set; call the other Zero_Slots that takes a range of slot offsets. Call the new Mutate_Kind that takes an Old_Size, for the same reason -- the size cannot be computed without the Nkind. (Mutate_Nkind): New function that allows specifying the Old_Size. (Size_In_Slots): Assert that the Nkind has proper (nonzero) value. * atree.ads: Minor reformatting.
