[PATCH] vect: Add bias parameter for partial vectorization
Tue Nov 2 20:16:29 GMT 2021
thanks for the helpful comments. The attached v2 addresses the following
points from them:
- Save the bias in loop_vinfo and set it once in vect_verify_loop_lens.
- Add code to handle the bias in vect_set_loop_controls_directly.
- Adjust costing.
- Add comments for the new len_load parameter as well as change wording.
- Include the rs6000 change directly.
I'm not entirely satisfied with the bias code for the loop controls,
mainly because of side effects I might not have considered. The test
suites show no new regressions and bootstrap succeeded, though.
