You have to count all uses of: SOURCE_LINE, SOURCE_COLUMN, MAIN_FILE_P, LAST_SOURCE_LINE, LAST_SOURCE_LINE_LOCATION, and LINEMAP_POSITION_FOR_COLUMN which are all macros. Also, line-map functions seem to be in the critical path, so the extra dereferencing may be noticeable. > There are 2 more uses in makedepend.c, which could define its own dummy > functions because it does not care about locations at all. Sure about that? line-map.h seems pretty important to handle the include stack. Cheers, Manuel.
