These warnings started appearing recently when building LLVM: llvm[2]: Compiling LLParser.cpp for Release build /Volumes/Data/Users/kremenek/llvm/lib/AsmParser/LLParser.cpp: In member function ‘bool llvm::LLParser::ParseBr(llvm::Instruction*&, llvm::LLParser::PerFunctionState&)’: /Volumes/Data/Users/kremenek/llvm/lib/AsmParser/LLParser.cpp:3195: warning: ‘Op1’ may be used uninitialized in

So i have a testcase (see PR31792, and cond_br2.llin GVN) that current GVN can simplify because it replaces instructions as it goes. It's an example of a larger issue that pops up quite a lot I would appreciate thoughts on what to do about it it amounts to something like this (but again, it happens a lot): live = gep thing, 0 live2 = gep thing, 1 branch i1 provablytrue,, mergeblock, otherbb

On cygwin-1.7, clang and llvm can be built fine through 3 stages. With --disable-assertions (RC3's default), I saw a few warnings in llvm/lib/AsmParser/LLParser.cpp with g++-4.3.4.

Hi, I learning samba on SUSE 9.3 linux box. I followed the Samba "Small Office Networking" example to configure the server, but I have problem to access the share "accounts" / finsvcs until I changed the valid users from %G to @acctsdep. Here are the output from the console when I accessing the share "accounts" server01:~ # smbclient //server01/accounts -U

Hi folks, Hope this is not a silly question. But it bothers me when I am thinking about it. My question is: 1. In the implementation of serverSplitPHINodes(), why it only checks the first PHI node for possible multiple inputs from outside the region to extract. There could be more than one PHI nodes in the header block, and the code only checks the first one. I don't quite get it.

Hi all, Can somebody explain why length("") returns 1 and not 0? How do I test if a given string is the empty string? Thanks, Steffen. [[alternative HTML version deleted]]

Hello list, I wish to report a problem with openvpn tunnels. Synopsis: Despite adding policies to the shorewall policy file, I have to add extra rules to allow the UDP port 5000 packets to get through. I have used no particular setup guide. I believe this problem goes away with shorewall 2.0.9, as I have implemented openvpn with that version on a different machine, and I see no UDP:5000 packet

Dear llvm guys, I am trying to add the BreakCriticalEdges pass to my application. I tried to add it to the PNE pass (e.g. PHIElimination.cpp - AU.addRequiredID(BreakCriticalEdgesID); ), but I get this error: llc -f -regalloc=simple Base1Sum.bc -o simple.s ----------------------------------------------- llc: PassManagerT.h:387: void llvm::PassManagerT<Trait>::markPassUsed(const

The 2.1.0p2 and 2.1.0p3 RPMS try to fall back to the r* commands in /usr/kerberos/bin. I'm not sure under which distribution that path is valid, but it just gives an error on my machines (RedHat 6.1 and 6.2). It's no big deal to tweak the SRPM and build my own packages, but it does make me wonder if the fallback path should be configurable. -- Jason L Tibbitts III - tibbs at uh.edu -

It's a week until the semester starts, so what better time to dump on the sysadmin (me)! I've been told that I must have Geometer's Sketchpad running in a small (20-seat) Linux-based computer lab and I have a week to do it. Just another pothole on the freeway of life. So I've turned to Wine, which I have only superficial knowledge of. The FC3 RPM from WineHQ, though a bit

Hello: I just installed samba 2.0.0 here on my Linux 2.2.5 box and it is working...sort of. Here is the problem: I can browse the shares and see what's there but anytime I click on a folder shown there I get a message similar to: \\EAGLE\root\file does not exist yet I KNOW the files directory is there and I can obviously see it. What am I missing here? George George, MR. Tibbs & The

Dear list, I am having a problem with openvpn. I have the following arrangement, running two instances of openvpn on "home fw". I want to protect my WLAN in back of the home fw and that works fine. I can see "Peer connection initiated with 192.168.1.3:5000" in daemon.log on homefw. Nothing gets initiated with officefw, nor can I ping the other end of the tunnel at officefw.

OK, here's a new patch that adds the infrastructure and the implementation for X86, ARM and PPC of GetInstSize and GetFunctionSize. Both functions are virtual functions defined in TargetInstrInfo.h. For X86, I moved some commodity functions from X86CodeEmitter to X86InstrInfo. What do you think? Nicolas Evan Cheng wrote: > > I think both of these belong to TargetInstrInfo. And

Hi, I'm writing a ModulePass that needs critical edges split up. I have the statement AU.addRequiredID(BreakCriticalEdgesID); in my getAnalysisUsage() but the pass never gets executed. I guess I have to request pass execution for each function, but I can't get behind how to do that, since there is no analysis group for that kind of transformation. Thanks, Andi

Hi Hongbin I am not quite familiar with AnalysisUsage, let me correct question a bit. I have read Writing Pass <http://llvm.org/docs/WritingAnLLVMPass.html#specifying-interactions-between-passes>, All examples that i see here are based on collecting information .i.e Analysis Passes. I wonder if this applies to Transformation passes also. e.g. void MyInliner::getAnalysisUsage(AnalysisUsage
