This proposed patch adds some spelling corrections to the fortran frontend. Suggestions are printed if we can find a suitable name, currently perusing a very simple cutoff factor: /* If more than half of the letters were misspelled, the suggestion is likely to be meaningless. */ cutoff = MAX (strlen (typo), strlen (best_guess)) / 2; which effectively skips names with less than 4 characters. For e.g. structures, one could try to be much smarter in an attempt to also provide suggestions for single-letter members/components. This patch covers (at least partly): - user-defined operators - structures (types and their components) - functions - symbols (variables) If anybody has a testcase where a spelling-suggestion would make sense then please pass it along so we maybe can add support for GCC-7. Changes for v1 -> v2: - subroutines using interfaces - keyword arguments (named parameters) Rewrite C++ autovec in plain C. Factor out levenshtein distance handling into a commonly used gfc_closest_fuzzy_match().
