C: add fixit hint to misspelled field names

[gcc.git] / gcc / c / ChangeLog

2016-06-07  David Malcolm  <dmalcolm@redhat.com>

        * c-parser.c (c_parser_postfix_expression): In __builtin_offsetof
        and structure element reference, capture the location of the
        element name token and pass it to build_component_ref.
        (c_parser_postfix_expression_after_primary): Likewise for
        structure element dereference.
        (c_parser_omp_variable_list): Likewise for
        OMP_CLAUSE_{_CACHE, MAP, FROM, TO},
        * c-tree.h (build_component_ref): Add location_t param.
        * c-typeck.c (build_component_ref): Add location_t param
        COMPONENT_LOC.  Use it, if available, when issuing hints about
        mispelled member names to provide a fixit replacement hint.
