--- Comment #9 from alalaw01 at gcc dot gnu.org ---
In analyze_access_subtree (since r147980, "New implementation of SRA", 2009):
else if (root->grp_write || TREE_CODE (root->base) == PARM_DECL)
root->grp_unscalarized_data = 1; /* not covered and written to */
adding a case for constant_decl_p alongside the PARM_DECL case, fixes the ICE;
AArch64 bootstrap in progress.
