That one demangles to `void * __ptr64 __cdecl operator new(unsigned __int64)`,
so the problem is more likely to be with:
`declare dso_local void @"??3@YAXPEAX_K@Z"(ptr noundef %0, i64 noundef %1) #1`
because that demangles to `void __cdecl operator delete(void * __ptr64,unsigned
__int64)`.
Not entirely certain what you're asking, but MSVC CRT does have a definition
for sized delete:
```
_CRT_SECURITYCRITICAL_ATTRIBUTE
void __CRTDECL operator delete(void* const block, size_t const) noexcept
{
operator delete(block);
}
```
in `crt\src\vcruntime\delete_scalar_size.cpp`
