Commit Message

Richard Biener April 17, 2024, 9:25 a.m. UTC 
The following makes sure to reset LOOP_VINFO_USING_PARTIAL_VECTORS_P
to its default of false when re-trying without SLP as otherwise
analysis may run into bogus asserts.

Bootstrapped on x86_64-unknown-linux-gnu, testing in progress.

Richard.

	PR tree-optimization/114749
	* tree-vect-loop.cc (vect_analyze_loop_2): Reset
	LOOP_VINFO_USING_PARTIAL_VECTORS_P when re-trying without SLP.
