...ions can be nested.
As a quick example, something like:
int main() {
int a;
#pragma omp parallel firstprivate(a)
do_something(a)
...
}
becomes something like:
define private void @parreg(i32 %a) {
entry:
call void @do_something(i32 %a)
ret
}
define i32 @main() {
entry:
...
call void @parreg1(i32 %a) !parallel !0
...
!0 = metadata !{ metadata !"region", @parreg }

pass-by-pointer parameter to the function. The pointer refers to an
array of values, one for each thread that will execute the r...
