For the expand_omp_target hunk, a testcase would be e.g.
int
main ()
{
int n = 0;
#pragma omp target map(tofrom:n)
#pragma omp for reduction (+: n)
for (int i = [](){ return 3; }(); i < 10; ++i)
n++;
if (n != 7)
__builtin_abort ();
}
For tasking as opposed to parallel, testcase that ICEs is e.g.:
int
main ()
{
int n = 0;
#pragma omp task shared (n)
for (int i = [](){ return 3; }(); i < 10; ++i)
n = i;
#pragma omp taskwait
if (n != 7)
__builtin_abort ();
}
For grid, you want Martin to write a testcase ;).
Regarding finalize_task_copyfn, this is for an artificial function created for
constructors of firstprivate vars in task, like:
struct S { S (); ~S (); S (const S &); };
void foo (S &);
void
bar ()
{
S s;
#pragma omp task firstprivate (s)
foo (s);
}
The *cpyfn* for this looks like:
try
{
{
.omp_data_o.3_1 = .omp_data_o;
_2 = &.omp_data_o.3_1->s;
_3 = .omp_data_i->s;
S::S (_2, _3);
return;
}
}
catch
{
<<<eh_must_not_throw (terminate)>>>
}
and is not actually outlined from the original function, but rather constructed
from scratch. Couldn't get ICE on it, so let's ignore that for now.
