Yes, I think you're right.  HeaderMayThrow is a conservative approximation, and the conservativeness is biting us here. > Are there any plans to

hi all, i have SCEVAddRec {{(32 + @edge.8265),+,32}<Loop0>,+,4}<Loop1> where Loop0 and Loop1 are brothers (loops at the same level of the loopnest), and Loop0 have a computable backedge taken count. when i call getSCEVAtScope({{(32 + @edge.8265),+,32}<Loop0>,+,4}<Loop1> , Loop1), it just give me a {{(32 + @edge.8265),+,32}<Loop0>,+,4}<Loop1>, instead of

Dear All, Is the following patch to ScalarEvolution correct? It seems that without it, the enclosing for loop could skip over SCEVAddRecExpr's in the Ops[] array. -- John T. -------------- next part -------------- An embedded and charset-unspecified text was scrubbed...

A customer has an expanding number of Mac computers. Last Friday and existing machine started having problems writing files to a Samba share on a CentOS 5.x server. They had no problems prior to Friday. They are getting permission failure errors in creating files and folders. I made the sare owned by the user and group with group write enabled. Even with him as the owner he can not write

Hi:    I want to do some optimization on MachineLoop. So I want to get MachineLoopInfo from MachineFunction. I reference MachineLICM.cpp. So I try to write a pass in Target/mytarget directory. I find there is Error. llvm/include/llvm/PassAnalysisSupport.h:198: AnalysisType& llvm::Pass::getAnalysisID(const llvm::PassInfo*) const [with AnalysisType = llvm::MachineLoopInfo]: Assertion

Hi, I have an strange issue on our company network. We run samba4 ad-dc's on four branches as separate sites, they are connected via ipsec tunnels, all servers are debian wheezy systems using sernet 4.1.9-8 samba packages. We use roaming profiles with folder redirection configured via GPo's. In tree of the four branches users suddenly losse the connection to their home shares, since

Old managers will change its the LaLawyershat don't change. Every dam law office that I been in has at least one fax machine that is constantly printing something out. But to say fax is dead is an understatement. AT&T said that about teletype service, you know 50 - 300 baud service, years ago and then one day they noticed that traffic across their teletype seservicetarted growing. If

i am getting seg fault on functions like I->eraseFromParent also. I'm assuming that the problem comes when i change the loop structure.

I'm interested in using smbclient in an embedded Linux system, to copy files to a Windows file share. I don't need the entire samba suite. I'd like to get a smbclient compile that is reasonably small (less than 3 MB ideally). I'm building the embedded Linux system cross-compiled for an ARM based platform using Yocto. Yocto has support for building samba. But it is aimed at the

The funny thing is that i am manually able to hoist the Loop invariant instruction to the basicBlock terminator, by editing the human readable form and then using llvm-as to convert it into bytecode.

Yes, I can get "SCEVAddRecExpr" from operands of "(sext i32 {2,+,2}<%for.body4> to i64)". So whenever SCEV cast to "SCEVAddRecExpr" fails, we have drill down for such patterns ?

In the past I've used a combination of spamhaus combined RBL's and Spamassassin with Mailscanner as my spam recipe, but this stopped working very well for me well over a year ago. As many of the users of the couple small/personal mail servers I run are NOT technical people, and use POP to read their mail, 'training' spamassassin is difficult at best. Once upon a time, using

Hi, How does LLVM identify induction variables of a loop? Is the algorithm based on SSA graphs? I have a complicated loop and I need to do some analysis around it. Can anyone please point me to source of identification part? -- *Disclaimer: Views, concerns, thoughts, questions, ideas expressed in this mail are of my own and my employer has no take in it. * Thank You.

How do you generate a SCEVAddRecExpr from a SCEV? It tried dyn_casting and it seems like that the SCEV returned by getSCEV is not a SCEVAddRecExpr.
