X-Git-Tag: basepoints/gcc-8~6286
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ad23a23ed29fb6ba8e60f63dcd879ca2284bf3ac;p=thirdparty%2Fgcc.git

Make 'loop iv compare' heuristics scanning more precise

	* gcc.dg/predict-1.c: Distinguish between "loop iv compare"
	and "guess loop iv compared" heuristics.
	* gcc.dg/predict-2.c: Likewise.
	* gcc.dg/predict-3.c: Likewise.
	* gcc.dg/predict-4.c: Likewise.
	* gcc.dg/predict-5.c: Likewise.
	* gcc.dg/predict-6.c: Likewise.
