155155
- Fixed fix-it hint for fold expressions. Clang now correctly places the suggested right
156156
parenthesis when diagnosing malformed fold expressions. (#GH151787)
157157

158+
- Fixed an issue where emitted format-signedness diagnostics were not associated with an appropriate
159+
diagnostic id. Besides being incorrect from an API standpoint, this was user visible, e.g.:
160+
"format specifies type 'unsigned int' but the argument has type 'int' [-Wformat]"
161+
"signedness of format specifier 'u' is incompatible with 'c' [-Wformat]"
162+
This was misleading, because even though -Wformat is required in order to emit the diagnostics,
163+
the warning flag the user needs to concerned with here is -Wformat-signedness, which is also
164+
required and is not enabled by default. With the change you'll now see:
165+
"format specifies type 'unsigned int' but the argument has type 'int', which differs in signedness [-Wformat-signedness]"
166+
"signedness of format specifier 'u' is incompatible with 'c' [-Wformat-signedness]"
167+
and the API-visible diagnostic id will be appropriate.
