Hello,
I encountered a problem: alignas not work with templates.
Here is my test:
typedef xx al_type alignas(32);
al_type a, b;
cout << alignof(al_type) << endl;
cout << alignof(a) << endl;
cout << alignof(b) << endl;
That's OK:
xx = simple type - eg double
xx = array - eg int[4711]
xx = simple stuct / class
output:
32
32
32
That will not work:
xx = template <typename _Type> class Example {};
output:
1
32
1
xx = template <typename _Type> class Example
{
_Type values[4711];
};
output:
sizeof(_Type)
32
sizeof(_Type)
I used cygwin gcc 4.9.2 / 32
Another question I have:
is the ggc supported in the foreseeable future pragmas or keywords
to selectively enable and disable the auto-vectorizing? (eg #pragma(novector))
__attribute __((optimize ("no-tree-vectorize"))) does not work with inline functions.
Thanks for the help
Gero
