ed1797ddf8285f59a50d9c883beb97705279d980 c++: Disable -Wignored-qualifiers for template args [PR107492]
It seems wrong to issue a -Wignored-qualifiers warning for code like:
static_assert(!is_same_v<void(*)(), const void(*)()>);
because there the qualifier matters. Likewise in template
specialization:
template<typename T> struct S { };
template<> struct S<void(*)()> { };
template<> struct S<const void(*)()> { }; // OK, not a redefinition
And likewise in other type-id contexts such as trailing-return-type:
auto g() -> const void (*)();
This patch limits the warning to the function declaration context only.
