d a loop len. Just in this case this particular order would
be important.

Hi, Richard and Richi.
This patch add support live vectorization by VEC_EXTRACT for LEN loop control.
Consider this following case:
#include
#define EXTRACT_LAST(TYPE) \
TYPE __attribute__ ((noinline, noclone)) \
test_##TYPE (TYPE *x, int n, T
