Hi, I've been writing an optimization pass (described on the ML previously). Sometimes this pass removes some case entries from switch instructions, which cause an abort because removeCase() doesn't fix the PHINodes predecessors when needed. e.g.: define i32 @foo() nounwind { ifthen: %call = call i32 @bar() switch i32 %call, label %myphi [ i32 0, label %ifelse i32 1, label %ifelse ] ifelse: br label %myphi myphi: %ret.0 = phi i32 [ 0, %ifthen ], [ 1, %ifelse ] ret i32 %ret.0 } Suppose I remove the default target (i.e. replace it with other target BB). I get the...

Hi All, I am using a specialized aggregation function to reduce a dataset with multiple rows per id down to 1 row per id. My function work perfect when there are >1 id but alters the 'var.g' in undesirable ways when this condition is not met, Therefore, I have been trying ifthen() statements to keep the original value when length of unique id == 1 but I cannot get it to work. e.g.: #function to aggregate effect sizes: aggs <- function(g, n.1, n.2, cor = .50) { n.1 <- mean(n.1) n.2 <- mean(n.2) N_ES <- length(g) corr.mat <- matrix (rep(cor, N_ES^2),...

Hi, I came across the below error when I try to do ifelse condition:- Error in "[<-"(`*tmp*`, test, value = rep(yes, length = length(ans))[test]) : incompatible types What I am trying to accomplish is :- for(x in 1:ncol(filterpred)){ sumno<-sum(filterpred[no,x]) sumyes<-sum(filterpred[yes,x]) ifelse(sumno==0 && sumyes !=0,

I like how some cds, such as the windows installer discs will skip booting from the disc if you accidentally left the drive because they require you to hit a key to make them actually boot from the disc. I've kind of tried to emulate this behavior using chain.c32, but, it requires me to specify which harddrive, and I'd rather see an independant setup. I've tried localboot -1, but, it

We would like to develop a code generator using LLVM for a target language that does not support conditional branches and in fact only supports structured control flow, eg. If and while. As far as I can tell that the problem with doing this in LLVM today, is that it does not support these high-level constructs and instead all control flow is implemented as branches. It is ³fairly²

I find Sweave very useful and I was trying to combine it with the latex package fancyvrb. I was trying to get line numbering and labels in order to reference the lines where particular commands occur. Unfortunately, I haven't been able to figure out how to do it. Maybe somebody can help me. The following is a sample Rnw file: the first part shows what I would like to get, the second what I

...to me. Is there a better way to do this? I have tried to do my homework, see below. Do I get partial credit ;-) ? Thank you all for your time! Stephan ######################################### I can't simply start a for loop within an R chunk and finish it in another one. whiledo in the ifthen.sty package doesn't like Sweave at all. And of course, it would simply reuse the R chunks if it did work, without changing things between loops. For the same reason, I cannot define a \newcommand{\loopcontent}{...} with the entire loop contents and then simply write \loopcontent \loopcontent .....
