------- Comment #9 from acahalan at gmail dot com 2006-04-23 02:05 ------- Actually, there is no desire to prevent sibling calls. That's a hack. Sibling calls are desirable as long as they don't muck with the incoming argument stack.
Using -fno-sibcalling is definitely out of the question. It would affect other functions. Note: the kernel uses -mregparm=3 as the default. Once indexed by Google, a query for "slightly different macro that talks less about tailcalls" ought to find some more discussion of this. Google groups has it already. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27234
