i don't know where to ask this but is there a direct link to the Microsoft ABI
document? The behavior i observed on MSVC was keeping same type in an alignment
window while filling all bits of a type, but clang gives this warning even if
that is satisfied.
For example this is compatible between MSVC and clang
```cpp
struct Foo
{
uint64_t x: 44;
uint64_t y: 20;
//struct alignment is 8 bytes, we filled all uint64_t bits so moving to
another type should not be a problem
uint32_t s; 20;
uint32_t s; 12;
//we filled 32 bits of uint32_t but alignment window is not filled so we
should still continue with uint32_t
uint32_t a; ;13;
uint32_t b ;3;
uint32_t c; ;13;
uint32_t d ;3;
};
```
