Commit Message

Richard Biener July 25, 2024, 10:44 a.m. UTC 
The following addresses a behavioral difference in vector type
analysis for typedef vs. non-typedef.  It doesn't fix the issue
at hand but avoids a spurious difference in the dumps.

Bootstrapped and tested on x86_64-unknown-linux-gnu, pushed.

	PR tree-optimization/116081
	* tree-vect-stmts.cc (vect_get_vector_types_for_stmt):
	Properly compare types.
