Hello David, Thanks for the reply. Would i not need to pass any arguments for viewCFGOnly() method? According to this http://llvm.org/doxygen/Function_8h-source.html seems like we need to? I am building it on top of the example shown at http://llvm.org/docs/WritingAnLLVMPass.html and just added 'F->viewCFGOnly(); line to it. It doesn't compile, i suspect it has to do with...

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() con...

Hello All, I am trying to get basic CFG display to work. I have read the programmer's manual and it mentions that we can simply call the viewCFGOnly() (part of Function.h) from our sample program. When i read the comments for that method in Function.h, it mentions that i need to call it from the gdb debugger instead. I am confused as to how to get this working. Do we need to call it from a simple program or a debugger. An example would be ver...

You can call the function from your program OR the debugger. The comments simply inform you that it is quite handy to be able to call the function from a debugger (such as gdb). To call the function in you code simply add a line such as: F->viewCFGOnly(); Where F is an appropriate variable eg. a MachineFunction pointer If you are using gdb then you can do the following: call F->viewCFGOnly() from a point where F is live.

...GraphWriter on these data structures. 3. The file DomPrinter.cpp containing the actual passes, printers & Co. It is simple as almost everything already existed. 4. A little bug fix in lib/Analysis/CFGPrinter.cpp. virtual bool runOnFunction(Function &F) { - F.viewCFG(); + F.viewCFGOnly(); return false; "opt -view-cfg-only" showed too much. Any feedback is highly appreciated. See you Tobi

...rget-independent live-variable analysis is quicker and simpler than before. 15. Vladimir Prus contributed code generator support for targets that have object alignments bigger than their size (e.g. bytes aligned on 32-bit boundaries). 16. Alkis implemented MachineFunction::viewCFG and ::viewCFGOnly methods, which make it really easy to visualize machine code in a debugger (operating like the Function::viewCFG method). Note that this does not work with the SparcV9 target yet. 17. The LLVM llc and lli tools now support dynamically loaded target implementations: http://mail.cs...
