Subject: fix CTOR vectorization
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3d42842c07f4143042f3dcc39a050b262bcf1b55;p=gcc.git

fix CTOR vectorization

We failed to handle pattern stmts appropriately.

2020-03-20  Richard Biener  <rguenther@suse.de>

	* tree-vect-slp.c (vect_analyze_slp_instance): Push the stmts
	to vectorize for CTOR defs.
