2017-10-17Simplify format_warning_at_substring APIDavid Malcolm6-71/+81
The format_warning_at_substring API has a rather clunk way of indicating the location of the pertinent param (if any): a source_range * is passed in, which can be NULL. Doing so requires extracting a range from the location_t and passing around a pointer to it, or NULL, as needed. This patch simplifies things by eliminating the source_range * in favor of a location_t, with UNKNOWN_LOCATION used to signify that no param location is available. gcc/c-family/ChangeLog: * c-format.c (format_warning_at_char): Pass UNKNOWN_LOCATION rather than NULL to format_warning_va.
