>Description:
Compiling this code: (g++ -msse)
struct v8qi {
typedef int T __attribute__ ((mode(V8QI)));
v8qi() {
long long int tmp;
__builtin_ia32_punpckhbw((T) tmp, (T) tmp);
};
};
does NOT work. The error is:
test16.cpp:5: error: cannot convert `int' to `vector signed char' for argument
`1' to `vector signed char __builtin_ia32_punpckhbw(vector signed char,
vector signed char)'
But when you move the typedef out of the struct, you get this:
typedef int T __attribute__ ((mode(V8QI)));
struct v8qi {
v8qi() {
long long int tmp;
__builtin_ia32_punpckhbw((T) tmp, (T) tmp);
};
};
which DOES compile!! It seems that using __attribute__ ((mode(..))) on a typedef inside a struct/class does not work. Any ideas?
