There are just no instructions for that but you have to pretend you
have to get code vectorized.

How do you declare those?
Something like this:
#pragma omp declare simd inbranch
int foo(int*);
The 'inbranch' is the thing that matters? And all of foo is then
implicitely predicated?
If it is
#pragma omp declare
