Commit Message

Richard Biener Feb. 11, 2022, 10:28 a.m. UTC 
This fixes vectorized_internal_fn_supported_p behavior when
facing vector types with an integer mode.

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

2022-02-11  Richard Biener  <rguenther@suse.de>

	PR middle-end/104496
	* internal-fn.cc (vectorized_internal_fn_supported_p):
	Bail out for integer mode vector types.

	* gcc.target/i386/pr104496.c: New testcase.
