We had this discussion last year. The only reason to still have libcalls was for TLS address calls. You already fixed that. To the best of my knowledge the only other thing libcalls are still "useful" for, is scheduling of groups of insns (iirc it's SCHED_GROUP_P or something like that). And didn't you mention an fwrapv issue that's currently papered over by libcall notes?? Gr. Steven
