1998-11-26 01:17 -0500 Zack Weinberg <zack@rabi.phys.columbia.edu> * cpplib.h (struct cpp_buffer): Replace dir and dlen members with a struct file_name_list pointer. (struct cpp_reader): Add pointer to chain of `actual directory' include searchpath entries. (struct file_name_list): Add *alloc pointer for the sake of the actual-directory chain. Move definition of HOST_WIDE_INT here. (cpp_parse_escape): Change prototype to match changes in cppexp.c. * cppfiles.c (actual_directory): New function. (finclude): Use it to initialize the buffer's actual_dir entry. (find_include_file): We don't need to fix up max_include_len here. * cpplib.c (do_include): Don't allocate a file_name_list on the fly for current directory "" includes, use the one that's been preallocated in pfile->buffer->actual_dir. Hoist out duplicate code from the search_start selection logic. (cpp_reader_init): Initialize pfile->actual_dirs. Remove definition of HOST_WIDE_INT. Change calls to cpp_parse_escape to match changes in cppexp.c (note hardcoded MASK, which is safe since this is the source character set). * cppexp.c: Bring over changes to cpp_parse_escape from cccp.c to handle wide character constants in #if directives. The function now returns a HOST_WIDE_INT, and takes a third argument which is a binary mask for all legal values (0x00ff for 8-bit `char', 0xffff for 16-bit `wchar_t', etc.) Define MAX_CHAR_TYPE_MASK and MAX_WCHAR_TYPE_MASK. Change callers of cpp_parse_escape to match. [Fixes c-torture/execute/widechar-1.c] From-SVN: r24153 |
