Re: altivec still broken?!


I suspect we may be in need of a target hook :-) for VECTOR_TYPE comparison, since it appears that SPE and AltiVec (not to mention MMX/SSE) may require different semantics in this regard. A one-size-fits-all approach for vectors may not be feasible.

I actually found a bug that is solved in my implementation of comptypes. It is a contrived example and it is in C++, but is indeed a bug.

1  template <class T> class X {

5  };

7  typedef int v2si __attribute__ ((vector_size (8)));

10 };

With my patch, this compiles.  With rth's proposed resolution
of comptypes for vector types, instead it gives a wrong error

/home/utente/aaa.c:9: error: redefinition of `class X<int __vector__>'
/home/utente/aaa.c:4: error: previous definition of `class X<int __vector__>'
