Yes and that requires a lot of jump threading and many other optimizations to detect that really. First PRE has to be working and then VRP has to figure out it will be greater than 0. So really this code depends on optimization to work correctly and the kernel is broken that way again (not suppressing really) -- Pinski -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36359
