Bug ID: 108955
Summary: Ultimate++ fails with its specialized AssertMoveable
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: piotr5 at netscape dot net

my failed attempt at a minimal example after preprocessor
I'm on gentoo with sys-devel/gcc-13.0.1_pre20230219 and tried to recompile
anything using Ultimate++ from upp.sf.net and already the heaqders fail to
compile. error: invalid type argument of unary '*' (have 'unsigned int')
this indicates the pre-c++11 test for "unsigned int" being a moveable data-type
failed. I tried to reproduce the problem with a minimal example but that had no
such problems in compilation. the way it's supposed to work is Core/Topt.h:
```
template
inline void AssertMoveablePtr(T, T) {}
template
inline void AssertMoveable0(T *t) { AssertMoveablePtr(&**t, *t); }
// COMPILATION ERROR HERE MEANS TYPE T WAS NOT MARKED AS Moveable
template
struct Moveable_ {
friend void AssertMoveable0(T *) {}
};
template
inline void AssertMoveable(T *t = 0) { if(t) AssertMoveable0(t); }
#if defined(COMPILER_MSC) || defined(COMPILER_GCC) && (__GNUC__ < 4 ||
__GNUC_MINOR__ < 1)
#define NTL_MOVEABLE(T) inline void AssertMoveable0(T *) {}
#else
#define NTL_MOVEABLE(T) template<> inline void AssertMoveable(T *)
{}
#endif
NTL_MOVEABLE(bool)
NTL_MOVEABLE(char)
NTL_MOVEABLE(signed char)
NTL_MOVEABLE(unsigned char)
NTL_MOVEABLE(short)
NTL_MOVEABLE(unsigned short)
NTL_MOVEABLE(int)
NTL_MOVEABLE(unsigned int)
NTL_MOVEABLE(long)
NTL_MOVEABLE(unsigned long)
NTL_MOVEABLE(int64)
NTL_MOVEABLE(uint64)
NTL_MOVEABLE(float)
NTL_MOVEABLE(double)
NTL_MOVEABLE(void *)
NTL_MOVEABLE(const void *)
```
then in destructor for Vector there is
AssertMoveable((T *)0);
where T = unsigned int
what is supposed to happen is that NTL_MOVEABLE expands to
template<> inline void AssertMoveable(T *) {}
so far it works as expected. however upon encontering that AssertMoveable((T
*)0); it is expanded into
inline void AssertMoveable0(T *t) { AssertMoveablePtr(&**t, *t); }
instead. is it because that was defined in the wrong order? but then why did my
minimal example work? why is there no such problem with gcc-12?
