2483 | with a struct file_name_list pointer. | |
2484 | (struct cpp_reader): Add pointer to chain of `actual | |
2485 | directory' include searchpath entries. | |
2486 | (struct file_name_list): Add *alloc pointer for the sake of | |
2487 | the actual-directory chain. | |
2488 | ||
2489 | Move definition of HOST_WIDE_INT here. | |
2490 | (cpp_parse_escape): Change prototype to match changes in | |
2491 | cppexp.c. | |
2492 | ||
2493 | * cppfiles.c (actual_directory): New function. | |
2494 | (finclude): Use it to initialize the buffer's actual_dir | |
2495 | entry. | |

2497 | here. | |
2498 | ||

2500 | the fly for current directory "" includes, use the one that's | |
2501 | been preallocated in pfile->buffer->actual_dir. Hoist out | |
2502 | duplicate code from the search_start selection logic. | |
2503 | (cpp_reader_init): Initialize pfile->actual_dirs. | |
2504 | ||
2505 | Remove definition of HOST_WIDE_INT. Change calls | |
2506 | to cpp_parse_escape to match changes in cppexp.c (note | |
2507 | hardcoded MASK, which is safe since this is the source | |
2508 | character set). | |
2509 | ||
2510 | * cppexp.c: Bring over changes to cpp_parse_escape from cccp.c | |
2511 | to handle wide character constants in #if directives. The | |
2512 | function now returns a HOST_WIDE_INT, and takes a third | |
2513 | argument which is a binary mask for all legal values (0x00ff | |
2514 | for 8-bit `char', 0xffff for 16-bit `wchar_t', etc.) Define | |
2515 | MAX_CHAR_TYPE_MASK and MAX_WCHAR_TYPE_MASK. Change callers of | |
2516 | cpp_parse_escape to match. [Fixes c-torture/execute/widechar-1.c] | |

3209 | the wrong times. Until a VMSie can look at this, it's better | |
3210 | to not pretend to support it. | |
3211 | (append_include_chain): Change calling convention; now takes | |
3212 | only one directory at a time, and sets up the data structure | |
3213 | itself. | |

3233 | (do_pragma): Understand the include_hash structure. Reformat. | |
3234 | (do_endif): Correct handling of control macros. Understand | |
3235 | the include_hash. | |
3236 | (cpp_start_read): Fix up calls to finclude. Call | |
3237 | merge_include_chains. | |
3238 | (cpp_handle_option): Fix up calls to append_include_chain. | |
