Sorry I'm late. This is for BSDs if anyone is interested: * --hash-style=gnu doesn't work. * --sort-common has no problems. * -O1 makes a bit difficult (if not impossible) to obtain decent backtraces while debugging certain things. <unimportant side story> While -O1 works just fine for everything I've tested so far, if something fails and you want a backtrace out of a coredump or while debugging a binary, you may only get the last call, everything else on the stack is lost in 0xffffffff limbo. I experienced this while debugging a stack overflow in Python's cPickle, which could be the reason for this behavior (stack gone wild), but removing -O1 made decent dumps/traces. Of course I shouldn't have been debugging things with -Wl,-O1 in the first place but oh well :+) </> -- gentoo-dev@lists.gentoo.org mailing list
