similar to: [LLVMdev] Potential SimplifyCFG optimization; hammock to diamond transformation

All, I have some code that looks like the following: { double a, b, c; for (...) { ... a = lots of FP math; b = lots of FP math; c = lots of FP math; if (cond) { a = 0.0; b = 0.1; c = 0.2; } ... } } Could we not convert the hammock into a diamond and move the initial computation of a, b, and c into the else block. Something like this: {

Thanks, Mark. I will give the paper a look.

The specific code I'm looking at does not have any function calls. The "lots of FP math" is just a series of FP addition, subtraction and division.

Hi, I haven't found in R a possibility to draw a boxplot with a diamond shape (means and CI). Does anyone know how to plot it ? thanks,

Talking about Excel, you can produce excellent graphs in Excel. Yes you have to work at it, but you can get there. The problem is that they are not the default. My gut feeling is that R will make more of an impact in the presentation of graphics than any implementation in Excel. So even if a patent were granted and it made itself into a mainstream package, would it change the world or would the

Hi, does anyone have any idea how I might make a plot in R similar to this: http://assets.sbnation.com/assets/272612/BATTER-1B-PENA.png Specifically looking to plot 3 numbers in a triangle like that. [[alternative HTML version deleted]]

I'm trying to optimize a pattern that goes roughly as: A / \ B C \ / D Problem is, when A gets modified, B and C get added back to the worklist, but D doesn't. Readding D to the worklist just create an infinite loop where one process D again and again. Is there a proper way to make this work ? -------------- next part -------------- An HTML attachment was scrubbed...

I am looking to replicate the functionality of the JMP diamond plot in R. I have found the following enhancement and no other references(see below). I have tried to contact the author via email and I have had no luck. Does any know if this functionality exists in R? If it does not does anyone know how to contact the author of the enhancement request? "Hi, I experimented with a set of S

The root problem is that, when A gets modified, D doesn't get added back to the worklist. I could match the pattern on A, but the problem remains: when D gets modified, A do not get added back tot he worklist. I also considered ding several round of DAGCombine, but it is very easy to run into infinite loops, even with a fair amount of sanity checks. 2017-05-22 7:30 GMT-07:00 Nirav Davé

Explicitly re-adding a node to be processed doesn't work, because the processing order is canonical. 2017-05-22 11:39 GMT-07:00 Nirav Davé <niravd at google.com>: > You can always explicitly add D to the worklist when you make the > transformation with AddToWorklist.

Hi, Coincidentally I've been working to optimize this same case last week. I was struggling a bit to determine where to put this functionality and eventually went for the pragmatic approach of creating an experimental pass. Probably not the eventual solution, but it may provide some useful input to the discussion here. Basically, I experimented with a 'pre-inlining-transform' pass

I apologise for starting a new thread, but we had a mail problem and I don't have the original message to refer to. Someone mentioned the new "Diamond Graphs" invented at Johns Hopkins. I haven't see the August 2003 issue of The American Statistician yet, but I _have_ read the press release. The press release is a bit of a stunner. I quote: "Who would have thought we

Some time ago I was allowed to discuss "Diamond Graphs", and whether they would be useful in R, in this mailing list. The August 2003 issue of The American Statistician has finally arrived here and I have been able to read the article. A number of points of interest arise. 1. The article is "A Diamond-Shaped Equiponderant Graphical Display of the Effects of Two
