------- Comment #2 from eres at il dot ibm dot com 2007-11-25 11:21 ------- I have been testing Zdenek's initial lim patch on SPEC2006 and tramp3d but saw no effect on the preformance. We had an example which is similar to the testcase shown in (http://gcc.gnu.org/ml/gcc-patches/2007-03/txt00067.txt) which boosted the performance x1.5 due to the store motion (it also opened opportunity for the vectorizer). On the other hand; this patch may increased register pressure.
