Actually if you read the documention for -Wall, it says enable warnings that are easy to avoid. "This enables all the warnings about constructions that some users consider questionable, and that are easy to avoid (or modify to prevent the warning), even in conjunction with macros. " So really this warning is not easy to avoid in the case of -fprefetch-loop-arrays (or -funroll-loops if it comes and does (non complete) unroll at the tree level). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31058
