Subject: [Patch 2/8] parloops: Allow poly nit and bound
Date: Wed, 30 Aug 2023 10:08:27 +0100	[thread overview]

Teach parloops how to handle a poly nit and bound e ahead of the changes 
to enable non-constant simdlen.

gcc/ChangeLog:

	* tree-parloops.cc (try_to_transform_to_exit_first_loop_alt): Accept
	poly NIT and ALT_BOUND.
