substring_loc::get_location currently fails for the final terminator character in a STRING_CST from the C frontend, so that format_warning_va falls back to using the location of the string as a whole. This patch tweaks things [1] so that we use the final closing quote as the location of the terminator character, as requested in PR preprocessor/77672. [1] specifically, cpp_interpret_string_1. gcc/ChangeLog: PR preprocessor/77672 * input.c (selftest::test_lexer_string_locations_simple): Update test to expect location information of the terminator character at the location of the final closing quote.
