------- Comment #1 from pinskia at gcc dot gnu dot org 2006-07-13 05:37 ------- Note a related testcase is: #define vector __attribute__((vector_size(16))) float f(vector float t) { return *(float*)(&t); }
Which is only mentioned here in get_alias_set in the GCC sources as being not violating aliasing rules (see also http://gcc.gnu.org/ml/gcc/2006-07/msg00250.html). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28367
