Yes, given a BasicBlock*, you can iterate over the pred/succ blocks in the CFG like this: #include

Hello all, I am getting an undefined reference to Function::viewCFG() I have a function list iterator F and I am trying to get the CFG through F->viewCFG(); other function calls through the F pointer are working. - I have included the libraries: pthread, ffi, dl, m, LLVMAsmParse, LLVMCore, LLVMSupport, LLVMSystem. - I have dot and gv in my path, and I have reconfigured and rebuilt LLVM

July Status Update ------------------ Hi everyone! This month has been a busy month of cleanups and refinements, and marks over a year of LLVM status updates :). LLVM is getting substantially smaller (in memory footprint) and faster, received a few cool new features, and has a few more fixed bugs. We are currently thinking about unleashing the LLVM 1.3 release in about 3-4 weeks from now. If

Here's what the doxygen page has for viewCFGOnly() : /// viewCFGOnly - This function is meant for use from the debugger. It works /// just like viewCFG, but it does not include the contents of basic blocks /// into the nodes, just the label. If you are only interested in the CFG /// this can make the graph smaller. /// void viewCFGOnly() const; Which indicates that no arguments are

Happy to help. You'll probably find that other optimizations help as

I am doing inter-procedural static analysis, so I need to do DFS of call graph. llvm-gcc sometimes generates this kind of call instruction, which cause the call graph to be incomplete. But thanks for your information, instcombine really solves the problem. On 7/17/07, Chris Lattner <sabre at nondot.org> wrote: > > On Thu, 12 Jul 2007, Zhongxing Xu wrote: > > The current

Hey everyone, I want to call F.viewCFG() from within the Hello.so shared library runOnFunction() function, but I keep getting: opt: symbol lookup error: ../../../Debug/lib/LLVMHello.so: undefined symbol: _ZNK4llvm8Function7viewCFGEv while using: "opt -load ../../../Debug/lib/LLVMHello.so -print /temp/llvm/KellyTest/test.bc" I assume this means that I need to statically link in

Hi Ether, I work under Windows and am able to view graphs generated by LLVM. I haven't tried generating and viewing dog graphs while debugging but I hope this helps. What I do is to invoke llc.exe and pass a switch to generate the graph at the stage(s) you want to see (DAG combine, legalize, scheduling, etc), for example: llc.exe mykernel.ll -view-legalize-dags -f. The graphs are saved

Hi Ether, The detection for graphviz / dotty / ... has been added recently to llvm cmake. It should work properly if those tools are available in the PATH. The related svn commits are : 86153, 86547 and 86644. Those commits are not present in llvm release <= 2.6, but they are straight forward to apply.

hi all, i just install gv and dotty for windows, but i cant see any way to configure it using cmake. is Viewing graphs under windows supported? and how could i configure it? regards --ether

Hi, I started to work with llvm and liked the CFG dotty printer a lot. However there was none for the dominance trees. I implemented dotty printing for dominance trees and introduced these new flags: -dot-dom : Print dominance tree of function to 'dot' file -dot-dom-only : Print dominance tree of function to 'dot' file (with no function

LLVM doesn't use a specific search path to find the relevant executables for that feature. I don't see
