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? >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted:
