...d-alignment LLVM-IR for va_arg().    In some degree, llvm-gcc frontend depends on targets. The best solution is llvm-gcc can create va_arg node, I can lower it at the backend.    Who can give a temporary solution to make frontend can create 8 byte alignment code for long long type? Thanks     renkun. ___________________________________________________________ 好玩贺卡等你发，邮箱贺卡全新上线！ http://card.mail.cn.yahoo.com/ -------------- next part -------------- An HTML attachment was scrubbed...

Thank you, Nick. Yes, I have add getAnalysisUsage. As I know, some CFG is irreducible. At this time, Dominator Tree can not find some backedge. Is it means some MachineLoop is not be found? dominatorTree.jpg is a previous exmaple. best regards! renkun --- 10年3月9日，周二, Nick Lewycky <nicholas at mxc.ca> 写道： > 发件人: Nick Lewycky <nicholas at mxc.ca> > 主题: Re: [LLVMdev] Find all backedges of CFG by MachineDominatorTree. please look at my jpg. > 收件人: "任坤" <hbrenkun at yahoo.cn> > 抄送: "Benoit Boissinot&quo...

...ackedge form CFG. But I find A LOOP in some CFG, there is backedge from current to next, dominates function reture "FALSE". So my algorithm find Graph can not be toplogical sort. Is there a bug in MachineDominatorTree?? or MachineDominatorTree can not find all backedges??? Thanks renkun ___________________________________________________________ 好玩贺卡等你发，邮箱贺卡全新上线！ http://card.mail.cn.yahoo.com/

...s a backedge from current node to next node. move this backedge form CFG. But I find A LOOP in some CFG, there is backedge from current to next, dominates function reture "FALSE". So my algorithm find Graph can not be toplogical sort. 3. how do I find all backedges of CFG???

Dear maintainers, I'm reporting a bug in qr.coef that mishandles the colnames of matrix. A minimal reproducible example is as follows: x <- cbind(rep(0, 10), rep(0, 10)) y <- rep(0, 10) q <- qr.default(x) qr.coef(q, y) [1] NA NA If x has colnames, then qr.coef will end up with an error: x <- cbind(x1 = rep(0, 10), x2 = rep(0, 10)) y <- rep(0, 10) q <- qr.default(x)
