similar to: [LLVMdev] NULL successors exposed via GraphTraits

Hi there, I'm currently writing an analysis (for now) pass for LLVM that kind of need some information from the CallGraph of the program. This info would be extremely easy to get if I could build the DominatorTree information about the CallGraph. I even checked out and saw the declarations of GraphTraits templates for CallGraph and CallGraphNode, which might indicate that all algorithms that

I'm assuming that you're talking about a situation where this can't be determined statically in the existing LLVM IR, but you know it's true and want to put it in (e.g. you're the one generating LLVM IR). If that's not the case, then see if JumpThreading will do it for you. I'm not familiar with a way to express exactly what you want to say, but are you opposed to just

Hello, I’m trying to port a project up to 4.0 and I’m seeing the following error: In file included from /Users/jaredcarlson/Projects/llvm-4.0.0.src/include/llvm/ADT/StringRef.h:13: /Users/jaredcarlson/Projects/llvm-4.0.0.src/include/llvm/ADT/STLExtras.h:139:13: error: no type named 'type' in 'std::__1::result_of<std::__1::pointer_to_unary_function<llvm::DSNode *, llvm::DSNode

Suppose I have a bb with N predecessors and N successors. What is, in your opinion, the best way to express that the bb has (dynamically) only one successor (i.e. if coming from the i-th predecessor we will always jump to the i-th successor)? b.r., -- Carlo Alberto Ferraris <cafxx at strayorange.com <mailto:cafxx at strayorange.com>> website/blog

Hi, Can anyone tell me how to find successors and children of a basic-block ? What is the difference between successors and Children? Regards, Chayan

Hi, I use the llvm::ExtractCodeRegion to extract each loop into a separate function, but I have a problem when I run this on the SPEC CPU 2006 on the 401.bzip2 benchmark. First I use clang -O3 to generate optimized llvm code and then I extract some loops from the module built from blocksort.c source file. The problem is that the PHI nodes contained in the successors of the codeRepl

In Dominators.h, the splitBlock(NewBB) method assumes that the NewBB has only one successor. I don't see why it cant have more than one successors. Is there a reason? Or it's just assumed that way to simplify things? Thanks a lot. -- Wei Dang -------------- next part -------------- An HTML attachment was scrubbed... URL:

Correct. Or, more precisely, I'd like to investigate macro compression, i.e.

Hi All, I need to remove successors from every basic block to insert new ones I tried this code, but it doesn't work void RemoveSuccessor(TerminatorInst *TI, unsigned SuccNum) { assert(SuccNum < TI->getNumSuccessors() && "Trying to remove a nonexistant successor!"); // If our old successor block contains any PHI nodes, remove the entry in the //

Hi all, On PAE, two major issues: 2.6.23: kernel HVM Linux will boot failed if set acpi=1; SMP Fedora 7 can not be installed. On IA32E, Fedora 7 can not be installed successfully.

Are there any known race conditions with 2.6.18-194.26.1.el5 x86_64 and NFS4? Today a user managed to shut down two identical Intel servers by copying a simple text file via NFS4. Reverting back to 17.1 made the error disappear. On other non-identical hardware the error was not reproducible (so it must be a combination of hardware and this special kernel revision). Anybody interested in a

After a crash I tried wget http://debuginfo.centos.org/5/x86_64/kernel-debuginfo-2.6.18-194.32.1.el5.x86_64.rpm as usual. But for 32.1 there is no kernel-debuginfo. Is there any reason for that?

Many people seem to wait for the announcement of CentOS 6.0, so I want to share some test results I did with SL 6.0.. The actual 6.0 kernel can NOT allocate tape buffers when the server is heavily loaded at least on some LSILogic hardware. There is a big problem of slab buffer increase that can cause reboot/freeze of the server under load. Reported by many and verified by me :-( So perhaps

Hi guys, While trying to get dwarf debugging information to work with Win32 COFF targets, I came across a couple of issues with the current implementation of WinCOFFObjectWriter. Emitting empty section causes debug information to invalid, as the presence of certain debug section implies available information, and emission of labels as symbols confused gdb about the structure of the program. The

Hallo I am not familiar with any of packages you use (except of MASS and ggplot2) and the code is too complicated without any hint where the error could come from and what is the message you get. I wonder if anybody would like to go through your whole code. 1. data seems to be read correctly ICUData <- read.csv(file = "ICUData.csv", stringsAsFactors = TRUE) ICUData.neuro <-

If the CFG contains loops, how could this be possible? Anyway, no you can't use MBB numbers for that. Perhaps you need the MachineDominatorTree analysis? Regards, /jakob
