This adds the capability to locate the main file on the user or system include paths. That's extremely useful to users building header units. Searching has to be requiested (plain header-unit compilation will not search). Also, to make include_next work as expected when building a header unit, we add a mechanism to retrofit a non-searched source file as one on the include path. libcpp/ * include/cpplib.h (enum cpp_main_search): New. (struct cpp_options): Add main_search field. (cpp_main_loc): Declare. (cpp_retrofit_as_include): Declare. * internal.h (struct cpp_reader): Add main_loc field. (_cpp_in_main_source_file): Not main if main is a header. * init.c (cpp_read_main_file): Use main_search option to locate main file. Set main_loc * files.c (cpp_retrofit_as_include): New. |
