- Subject: [PATCH] Remove obsolete alias check in cgraph_redirect_edge_call_stmt_to_callee
Hi,
since (same body) aliases have their own cgraph_nodes, the check for
them in cgraph_redirect_edge_call_stmt_to_callee is now unnecessary
because e->callee is now the alias, not the function node.
The following patch therefore removes it. Bootstrapped and tested on
x86_64-linux, OK for trunk?
Thanks,
Martin
