PROFILE OUTPUT PROCESSING TOOLS FOR R ===================================== This package provides some simple tools for examining Rprof output and, in particular, extracting and viewing call graph information. Call graph information, including which direct calls where observed and how much time was spent in these calls, can be very useful in identifying performance bottlenecks.

LLVM does not need to construct a CFG, because the CFG is an explicit integral part of the program representation. Every BasicBlock ends

Alright, I can now see my hammocks being translated into phi nodes. Thanx for the info. I now have a question regarding the analyze tool. I noticed it has a -help option. I tried using the -print-cfg option. It creates a cfg.main.dot file. Is there a graphical tool I can use to view this graph ? Thanx, -- Vinay S. Belgaumkar

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

Just wanted to check in on this - did your patches make it past the prototype phase?

Sorry, I didn't notice that you are asking not to me but to Fangrui. Please disregard my previous email.

Dear Tianwei, You can use the -analyze option to the opt tool to tell the DSA passes to store their results in files. When you use the -analyze option, the DSA passes will create a separate file for each function (and possible one file to hold the globals graph). For this reason, I recommend running opt in a special empty directory because DSA will generate *a lot* of files. Second, to

You might have realized this already but it's probably not a good idea to use InputSection::Relocations for this because that ends up missing anything that becomes a dynamic relocation. I reckon that the code should be doing exactly what MarkLive.cpp is doing. Peter On Thu, Feb 28, 2019 at 5:15 PM Rui Ueyama via llvm-dev < llvm-dev at lists.llvm.org> wrote: > I hacked up a patch to

+1 for graphviz dot format, so that it can be consumed by any one of many existing graph visualization tools.

I'm an Rgraphviz newbie trying to figure out how to do some things/whether they are possible. Apparently graphviz does allow you to modify line widths of edges: see https://mailman.research.att.com/pipermail/graphviz-interest/2001q2/000051.html (although it looks a little obscure even in graphviz). [As discussed in the thread above, the "weight" parameter in Rgraphviz sets the

I don’t know if I can actually use LLVM due to its humongousness, but I hope the graph will be helpful to others attempting to comprehend LLVM. PNG attached; dot file

Hello, everyone! The code below allows me to produce the graph I want (I know - the colors are strange, but it's just for the sake of an example). After you run the plot<- part and then do print(plot) - that's what I want. However, when I run the bits of code below (with graphics devices) - what they print is different from the original plot. In .png, .emf, and .tiff - my dots change

Hello, I am a new user of LLVM and have been trying to find how Control Flow Graphs are implemented in it.I wish to get access to the internal structures of CFG and learn how LLVM makes them. Is there any existing tool that LLVM provides that makes CFG out of bytecode ? Thanks, Tanu --------------------------------- Do you Yahoo!? Check out the new Yahoo! Front Page. www.yahoo.com
