	PR middle-end/81007
	* ipa-polymorphic-call.c
	(ipa_polymorphic_call_context::restrict_to_inner_class):
	Skip FIELD_DECLs with error_mark_node type.
	* passes.def (all_lowering_passes): Run pass_build_cgraph_edges
	last again.

	* g++.dg/pr81007.C: New testcase.

	2017-06-14  Richard Biener  <rguenther@suse.de>

	PR tree-optimization/81083
	* tree-ssa-sccvn.c (vn_reference_lookup_3): Do not use abnormals
	as values.

	* gcc.dg/torture/pr81083.c: New testcase.

	PR gcov-profile/81080
	* configure.ac: Add AC_SYS_LARGEFILE.
	* libgcov.h: Include auto-target.h before tsystem.h to pick
	up _FILE_OFFSET_BITS which might differ for multilibs.
	* config.in: Regenerate.
	* configure: Likewise.
