Use t-glibc in tmake_file. Set target_has_targetcm. (tilegx-*-linux*, tilepro-*-linux*): Append to c_target_objs and cxx_target_objs rather than overriding previous value. * config/glibc-c.c, config/t-glibc: New. * doc/tm.texi.in (TARGET_C_PREINCLUDE): New @hook. * doc/tm.texi: Regenerate. * hooks.c (hook_constcharptr_void_null): New. * hooks.h (hook_constcharptr_void_null): Declare. gcc/c-family: * c-common.h (pch_cpp_save_state): Declare. * c-target.def (c_preinclude): New hook. * c-opts.c (done_preinclude): New. (push_command_line_include): Handle default preincluded header. (cb_file_change): Call pch_cpp_save_state when calling push_command_line_include. * c-pch.c (pch_ready_to_save_cpp_state, pch_cpp_state_saved) (pch_cpp_save_state): New. (pch_init): Call pch_cpp_save_state conditionally, instead of calling cpp_save_state. gcc/testsuite: * gcc.dg/c99-predef-1.c: New test. * gcc.dg/cpp/cmdlne-dU-1.c, gcc.dg/cpp/cmdlne-dU-2.c, gcc.dg/cpp/cmdlne-dU-3.c, gcc.dg/cpp/cmdlne-dU-4.c, gcc.dg/cpp/cmdlne-dU-5.c, gcc.dg/cpp/cmdlne-dU-6.c, gcc.dg/cpp/cmdlne-dU-7.c, gcc.dg/cpp/cmdlne-dU-8.c, gcc.dg/cpp/cmdlne-dU-9.c, gcc.dg/cpp/cmdlne-dU-10.c, gcc.dg/cpp/cmdlne-dU-11.c, gcc.dg/cpp/cmdlne-dU-12.c, gcc.dg/cpp/cmdlne-dU-13.c, gcc.dg/cpp/cmdlne-dU-14.c, gcc.dg/cpp/cmdlne-dU-15.c, gcc.dg/cpp/cmdlne-dU-16.c, gcc.dg/cpp/cmdlne-dU-17.c, gcc.dg/cpp/cmdlne-dU-18.c, gcc.dg/cpp/cmdlne-dU-19.c, gcc.dg/cpp/cmdlne-dU-20.c, gcc.dg/cpp/cmdlne-dU-21.c, gcc.dg/cpp/cmdlne-dU-22.c, gcc.dg/cpp/mi5.c, gcc.dg/cpp/multiline.c: Add -nostdinc to dg-options. libcpp: * files.c (struct _cpp_file): Add implicit_preinclude. (pch_open_file): Allow a previously opened implicitly included file. (_cpp_find_file): Add implicit_preinclude argument. Free file and do not call open_file_failed if implicit_preinclude. Store implicit_preinclude value. (_cpp_stack_include, _cpp_fake_include, _cpp_compare_file_date): Update calls to _cpp_find_file. (_cpp_stack_include): Handle IT_DEFAULT. (cpp_push_default_include): New. * include/cpplib.h (cpp_push_default_include): Declare. * init.c (cpp_read_main_file): Update call to _cpp_find_file. * internal.h (enum include_type): Add IT_DEFAULT. (_cpp_find_file): Update prototype.
