Subject: Check non-strictly vect_internal_def internal defs in integer_type_for_mask
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=94f203a3695d9779b84f41e36a295a90e7ba2f16;p=thirdparty%2Fgcc.git

Check non-strictly vect_internal_def internal defs in integer_type_for_mask

We are missing masks produced by inductions or reductions otherwise.

	* tree-vect-patterns.cc (integer_type_for_mask): Only
	reject vect_external_defs.
