[LLVMdev] how to eliminate dead infinite loops?
...t appears that the following code in LoopDeletion.cpp:152 is the culprit: ScalarEvolution& SE = getAnalysis<ScalarEvolution>(); const SCEV *S = SE.getMaxBackedgeTakenCount(L); if (isa<SCEVCouldNotCompute>(S)) return Changed; So, LoopDeletion thinks my loops might be infinite so it does not delete them - even if they do not write to any of the function return values. Is there a way to flag a loop as non-infinite? Or will I need to create my own modified loop deletion pass that can eliminate potentially infinite loops. Is it correct just to remove the above code...

Cannot clean infinite values
Hello all, I have to import numeric data from file but found it contains Infinite values which need to be eliminated. I tried to replace them in this way: data[which(data=="-Inf")] <- -0.3 data[which(data=="+Inf")] <- 0.3 But, somehow, the Infinite values stayed there. Any suggestions? regards, N. -- View this message in context: http://www.nab...

[LLVMdev] readonly and infinite loops
> You dropped some context... > A daemon program wouldn't be readonly. An infinite loop can be. Right. To prevent miscommunication, here is a quick analysis of a problematic (IMO) example: We start with ``` define void @infloop(i1 %c) { entry: br i1 %c, label %l, label %e l: br label %l e: ret void } define void @main_func() { entry: call void @infloop(i1 1)...

[LLVMdev] Is infinite empty loop dead code?
Hi, All: Is it legal to delete empty infinite loop like this : "while(1) {}"? It is interesting that both llvm and gcc keep the loop, however Open64 delete it. If it is safe to delete this loop, it would be lot easier to delete non-obvious dead loop like following as compiler doesn't need to prove if the loop in question...

Package 'MASS' (polr): Error in svd(X) : infinite or missing values in 'x'
Hello, I am trying to run an ordinal logistic regression (polr) using the package 'MASS'. I have successfully run other regression classes (glm, multinom) without much problem, but with the 'polr' class I get the following error: " Error in svd(X) : infinite or missing values in 'x' " which appears when I run the "summary" command. The data file is large (585000 rows) and has no NA, -9999 or blank values. My script (in brief) is as follows, with results: ############ > library(MASS) > > ## ADD DATA > Jdata<- re...

I do some google, I cannot find the answer... I check C std, I cannot find answer either. Delete infinite empty loop is boring, but if C/C++ lawyers could tell it is safe to to so, it would obviate the need to prove a non-countable loop infinite or not before DCE can delete it. That is the answer I'm waiting for to delete a disgusting dead non-countable loop in my way. On 11/14/2012 12:14 AM,...

Error: evaluation nested too deeply: infinite recursion / options(expressions=)?
Hi, I am processing tick data and my code has stopped working as I have increased the size of data being processed. Now I am receiving error for basic tasks in RConsole: > a = c(1:1000) Error: evaluation nested too deeply: infinite recursion / options(expressions=)? My R code worked fine with 50 stocks and 500,000 rows per stock, but when I increased this to 50 stocks and 5,000,000 rows per stock the code stopped halfway through with the above error message (Error: Evaluation nested too deeply.....).

[LLVMdev] readonly and infinite loops
Running -early-cse on declare void @rn() readnone nounwind define void @f() { entry: call void @rn() ret void } removes the call to @rn(). But @rn() could have had an infinite loop in it in which case @f() went from being a non-terminating program to an terminating no-op. Is this intentional? The only way I can see this transform being legal is if infinite loops are declared to have undefined behavior, but I could not find anything in the LLVM specification that menti...
