re PR c++/60553 (segfault in gt_ggc_mx_lang_tree_node in Chromium with LTO)
2014-03-19 Richard Biener <rguenther@suse.de>
PR middle-end/60553
* tree-core.h (tree_type_common): Re-order pointer members
to reduce recursion depth during GC walks.
lto/
* lto-tree.h (lang_tree_node): For types use TYPE_NEXT_VARIANT
instead of TREE_CHAIN as chain_next.
