* builtins.c (expand_builtin, expand_builtin_object_size,
expand_builtin_memory_chk, maybe_emit_chk_warning,
maybe_emit_sprintf_chk_warning): Use new %K format string specifier
for diagnostics.
* expr.c (expand_expr_real_1): Likewise.
* langhooks-def.h (struct diagnostic_info): Add forward decl.
(lhd_print_error_function): Add third argument.
* langhooks.h (struct diagnostic_info): Add forward decl.
(struct lang_hooks): Add third argument to print_error_function.
* diagnostic.h (diagnostic_info): Add abstract_origin field.
(diagnostic_last_function_changed, diagnostic_set_last_function): Add
second argument.
(diagnostic_report_current_function): Likewise.
* toplev.c (announce_function): Pass NULL as second argument to
diagnostic_set_last_function.
* diagnostic.c (diagnostic_report_current_function): Add second
argument, pass it as third argument to lang_hooks.print_error_function.
(default_diagnostic_starter): Pass DIAGNOSTIC as second argument
to diagnostic_report_current_function.
(diagnostic_report_diagnostic): Initialize diagnostic->abstract_origin
and message.abstract_origin.
(verbatim): Initialize abstract_origin.
* pretty-print.h (text_info): Add abstract_origin field.
* pretty-print.c (pp_base_format): Handle %K.
* langhooks.c (lhd_print_error_function): Add third argument. If
diagnostic->abstract_origin, print virtual backtrace.
* c-format.c (gcc_diag_char_table, gcc_tdiag_char_table,
gcc_cdiag_char_table, gcc_cxxdiag_char_table): Support %K.
(init_dynamic_diag_info): Likewise.
cp/
* error.c (cxx_print_error_function): Add third argument, pass
it over to lhd_print_error_function.
(cp_print_error_function): If diagnostic->abstract_origin, print
virtual backtrace.
* cp-tree.h (struct diagnostic_info): New forward decl.
(cxx_print_error_function): Add third argument.
testsuite/
* lib/prune.exp: Prune also "^In function .*$" lines and
"^ inlined from .*$" lines.
java/
* lang.c (java_print_error_function): Add third argument.
