Treat refs to arrays at struct end of external decls similar to refs to unconstrained commons. * gcc.dg/torture/pr85244-1.c: New testcase. * gcc.dg/torture/pr85244-2.c: Likewise. 2018-04-04 Richard Biener <rguent...@suse.de> PR tree-optimization/85168 * tree-ssa-sccvn.c (vn_reference_maybe_forwprop_address): Avoid propagating abnormals. * gcc.dg/torture/pr85168.c: New testcase. 2018-03-16 Richard Biener <rguent...@suse.de> PR c/84873 * c-gimplify.c (c_gimplify_expr): Revert previous change.
