Hello
I have backported the following patches for supporting non-rectangular loop
collapse from mainline to the devel/omp/gcc-10 branch:
7bfdb5a1c694cb9006e0478941e4443b230f5b98 openmp: Fix ICE on non-rectangular loop
with known 0 iterations
88528328ea560230f728af97110e89396c8267d2 openmp: Improve composite triangular
loop lowering and expansion
758fdf6514348a40ed424f3244cb25b92a005095 openmp: Add support for non-rectangular
loops in taskloop construct
4b2c33ef32f483ca78f6c7b3a5ee880aebe75b4c openmp: Handle even some combined
non-rectangular loops
3dd767906dab7d5456fc4c3a98134582b5f8a2ed openmp: Use more efficient logical ->
actual computation even if # iterations is computed at runtime

loop iterations more efficiently for some non-rectangular loops

logical iterator to actual iterators computation using search for quadratic
equation root(s)
