I think disabling these optimizations in workshare/parallel workshare
is reasonable, though perhaps you could enable it again in
EXEC_OMP_PARALLEL{,_DO,_SECTIONS} nested in the
EXEC_OMP_WORKSHARE/EXEC_OMP_PARALLEL_WORKSHARE.
E.g. in
$omp parallel workshare
a = b
$omp parallel
c = cos(d) + cos(d)
$omp end parallel
e = f
$omp end parallel workshare
the body of the inner $omp parallel can be optimized just fine.
