The existing directives-only code (a) punched a hole through the libcpp interface and (b) didn't support raw string literals. This reimplements this preprocessing mode. I added a proper callback interface, and adjusted c-ppoutput to use it. Sadly I cannot get rid of the libcpp/internal.h include for unrelated reasons. The new scanner is in lex.x, and works doing some backwards scanning when it finds a charater of interest. This reduces the number of cases one has to deal with in forward scanning. It may have different failure mode than forward scanning on bad tokenization. Finally, Moved some cpp tests from the c-specific dg.gcc/cpp directory to the c-c++-common/cpp shared directory, libcpp/ * directives-only.c: Delete. * Makefile.in (libcpp_a_OBJS, libcpp_a_SOURCES): Remove it. * include/cpplib.h (enum CPP_DO_task): New enum. (cpp_directive_only_preprocess): Declare. * internal.h (_cpp_dir_only_callbacks): Delete. (_cpp_preprocess_dir_only): Delete. * lex.c (do_peek_backslask, do_peek_next, do_peek_prev): New. (cpp_directives_only_process): New implementation. gcc/c-family/ Reimplement directives only processing. * c-ppoutput.c (token_streamer): Ne. (directives_only_cb): New. Swallow ... (print_lines_directives_only): ... this. (scan_translation_unit_directives_only): Reimplment using the published interface. gcc/testsuite/ * gcc.dg/cpp/counter-[23].c: Move to c-c+_-common/cpp. * gcc.dg/cpp/dir-only-*: Likewise. * c-c++-common/cpp/dir-only-[78].c: New. |

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
