[clang-format] `PointerAlignment` does not respect pointer to member field

[CDAlexanderW]

Environment

The tested v19 clang-format executable was built from latest source of 13.03.2024. Also tested with clang-format 17.0.3.

Setting in .clang-format is:

Language: Cpp
PointerAlignment: Left
SpaceAroundPointerQualifiers: Before

Problem

class A {
public:
  int B;
};
void function(int A::* parameter, int* parameter2) {
  int A::* variable = &A::B;
  int* A::B;
}

formats to

class A {
public:
  int B;
};
void function(int A::*parameter, int* parameter2) {
  int A::*variable = &A::B;
  int* A::B;
}

For the pointers to member field we expect the space between the ::* and the variable/parameter name to be there and NOT removed.

Is A:: a qualifier like const?

Is A:: a qualifier like const?

Hi owenca!
Thx for your reply.

No, not a qualifier. See (2) Pointer to member declarator on cppreference for the explanation of the language feature.

I knew A::* is for pointers to class members. I asked the question because I was thrown off by the SpaceAroundPointerQualifiers option and thought that maybe you expected A:: to be treated like a qualifier.
