# Description
As per before, an `omp_depend_t` remains a `kmp_depend_info_t *` allocated on
the heap.
This patch extends the `kmp_depend_info_t *` data structure caching its
associated `kmp_dephash_entry_t` after instanciating a depobj `obj` with `#
pragma omp depobj(obj) depend(...)`, hence removing a call to
`__kmp_dephash_find` on task constructs using `obj`.
# Notes
Regarding tests, we should probably maintain a header file with all runtime
data structure interfaces of interest to avoid code dupplication as currently.
# Evaluation
On 16x cores Intel(R) Xeon(R) Gold 5218 CPU @ 2.30GHz
10 runs on the same code, with/without the patch gives respectively `0.946 +/-
0.004 s.` and `1.046 +/- 0.007 s.`
`clang -fopenmp -Wall -Werror -Wextra -O0 main.c`
```C
# include <assert.h>
# include <omp.h>
# include <stdio.h>
static omp_depend_t obj;
# define N 16
static int x[N];
# define I (4096 * 64)
int
main(void)
{
double t0 = omp_get_wtime();
# pragma omp parallel
{
# pragma omp single nowait
{
# pragma omp depobj(obj) depend(iterator(i=0:N), out: x[i])
for (int i = 0 ; i < I ; ++i)
{
# pragma omp depobj(obj) update(out)
# pragma omp task depend(depobj: obj) shared(x) firstprivate(i)
{}
# pragma omp depobj(obj) update(in)
# pragma omp task depend(depobj: obj) shared(x) firstprivate(i)
{}
}
# pragma omp depobj(obj) destroy
# pragma omp taskwait
}
}
double tf = omp_get_wtime();
printf("Took %lf s.\n", tf - t0);
return 0;
}
```
