--- Comment #5 from Jeffrey A. Law <law at redhat dot com> ---
The released name comes from tree-ssa:
{
if (access_has_children_p (racc)
&& !racc->grp_unscalarized_data)
{
if (dump_file)
{
fprintf (dump_file, "Removing load: ");
print_gimple_stmt (dump_file, stmt, 0, 0);
}
generate_subtree_copies (racc->first_child, lhs,
racc->offset, 0, 0, gsi,
false, false, loc);
gcc_assert (stmt == gsi_stmt (*gsi));
unlink_stmt_vdef (stmt);
gsi_remove (gsi, true);
release_defs (stmt);
sra_stats.deleted++;
return SRA_AM_REMOVED;
}
The release_defs call releases the SSA_NAME back to the manager.
