Can you try this patchlet on top of those revs? It builds for me with this applied: diff --git a/gcc/graphite-sese-to-poly.c b/gcc/graphite-sese-to-poly.c index cdabd73..5712e58 100644 --- a/gcc/graphite-sese-to-poly.c +++ b/gcc/graphite-sese-to-poly.c @@ -1354,7 +1354,7 @@ build_sese_conditions_before (struct dom_walk_data *dw_data, if (e->flags & EDGE_TRUE_VALUE) VEC_safe_push (gimple, heap, *cases, stmt); else - VEC_safe_push (gimple, heap, *cases, NULL); + VEC_safe_push (gimple, heap, *cases, (gimple) NULL); } gbb = gbb_from_bb (bb);
