The following patch adds on top of the just posted #embed patch a first extension, gnu::offset which allows to seek in the data file (for seekable files, otherwise read and throw away). I think this is useful e.g. when some binary data start with some well known header which shouldn't be included in the data etc. 2024-09-12 Jakub Jelinek <jakub@redhat.com> libcpp/ * internal.h (struct cpp_embed_params): Add offset member. * directives.cc (EMBED_PARAMS): Add gnu::offset entry. (enum embed_param_kind): Add NUM_EMBED_STD_PARAMS. (_cpp_parse_embed_params): Use NUM_EMBED_STD_PARAMS rather than NUM_EMBED_PARAMS when parsing standard parameters. Parse gnu::offset parameter. * files.cc (struct _cpp_file): Add offset member. (_cpp_stack_embed): Handle params->offset. gcc/ * doc/cpp.texi (Binary Resource Inclusion): Document gnu::offset #embed parameter. gcc/testsuite/ * c-c++-common/cpp/embed-15.c: New test. * c-c++-common/cpp/embed-16.c: New test. * gcc.dg/cpp/embed-5.c: New test.
