Subject: tree-optimization/119858 - type mismatch with POINTER_PLUS
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1f7ac78efa622e19f38d6a45e857941b3dea1437;p=thirdparty%2Fgcc.git

tree-optimization/119858 - type mismatch with POINTER_PLUS

The recent PFA early-break vectorization fix left us with a POINTER_PLUS
and non-sizetype offset.

	PR tree-optimization/119858
	* tree-vect-loop.cc (vectorizable_live_operation): Convert
	pointer offset to sizetype.
