similar to: [LLVMdev] SelectionDAG viewers, filter-view-dags question

Daniel, We are using 3.6. Someone also pointed out that it was mandatory in 3.6.2 but I have not verified that.

I've just looked at my checkout of 3.6 and it looks like the fix wasn't merged. I don't have the revision number for the fix to hand but in lib/CodeGen/SelectionDAG/SelectionDAGISel.cpp, this: MatchFilterBB = (!FilterDAGBasicBlockName.empty() && FilterDAGBasicBlockName == FuncInfo->MBB->getBasicBlock()->getName().str());

Daniel, Ok, thanks. Simple fix. We'll just make correction in local copy for now, one less thing to port later :) Thanks.

Hi, It's changed a few times over the last year. I believe xdg-open spawns whichever application your desktop environment would use to open the file so you should be able to tell it to use dotty.

Hi I would like to view the various dags being output during codegen. Unfortunately, I am not seeing the files being dumped. I will really appreciate if someone can help me here llc switch.bc -f -view-dag-combine1-dags ( i tried -view-isel-dags, -view-sched-dags as well) Writing '/tmp/llvm_zbbAKM/dag.main.dot'... done. Writing '/tmp/llvm_G4rLKf/dag.main.dot'... done. Writing

After enabling assertions and recompilation I still get this error. ~/bin/llvm$ llc -view-isel-dags t3.bc llc: Unknown command line argument '-view-isel-dags'. Try: 'llc -help' llc: Did you mean '-fast-isel-abort'? and I see the view-edge bundles option but get the following error. ~/bin/llvm$ llc -view-edge-bundles t3.bc Writing

I'm trying to debug an issue in codegen but when using: llc -view-legalize-dags -O1 -march=x86-64 -o c-01.s c-opt.bc I get a .dot file and while it has the DAG the nodes do not have any text. I'm probably doing something very stupid but I cannot figure what it is can anyone point out what I'm doing wrong? Thanks, Ben I'm on Unbunto 9.3: dotty version 96c

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. Best regards, -- Arnaud de Grandmaison -----Original Message----- From: llvmdev-bounces at

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 eli, i delete the cache of cmake, and reconfigure the project, but HAVE_GRAPHVIZ still undefine. do you know what i should do? thanks very much. regards --ether On Tue, Dec 1, 2009 at 12:41 PM, Eli Friedman <eli.friedman at gmail.com> wrote: > On Mon, Nov 30, 2009 at 8:32 PM, ether zhhb <etherzhhb at gmail.com> wrote: >> hi all, >> >> i just install gv and

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

Matt, This seems to generate llvm.my_intrinsic just fine in the DAG, so no DAG errors; however, it won't match. For example, if I call the intrinsic from C, the DAG node looks to be named the same in dotty file but it won't match... am I missing something? I've done it exactly the way it was done above. The DAG looks great but it won't match. Did I miss something? Thanks.

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'm running ubuntu 12.04 and I'm trying to use dotty, the graphs are produced but without data - there are just dots in the nodes instead of text. Does anyone else have any trouble?

I was able to compile LLVM on windows (llvm2.3) using Visual studio. When I type llc -help command, I do not see -view-isel-dags option (http://llvm.org/docs/CodeGenerator.html document mentions about it). Is this option is supported on Windows (or Cygwin) build? Thanks a bunch, -Sanjay -------------- next part -------------- An HTML attachment was scrubbed... URL:

Yes, this is really a problem with the checks, not with the language. A simpler approach than your alternativeAssignment function would be simply to allow globalVariables() to be limited to a single function as the note in its help page says. This might be tedious to write by hand, but could be automated using methods like "dotify" in dotty. Duncan Murdoch On 12/03/2023 10:36
