------- Comment #9 from martsummsw at hotmail dot com 2006-08-27 13:21 ------- Hmmm - I am (also) wrong when I claimed it was solved in 4.1.1. It is improved since the example that goes wrong in #5 now is right, but it is just the limit (for when the compiler gets comfused) that is pushed a bit.
e.g. for (int bp=0;bp<11;++bp) // Up to 11 is fine unrolled in gcc 4.1.1 However 12 and above e.g. for (int bp=0;bp<12;++bp) // this still produces the poor performing code -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21827
