Dear all, I want to do the following process as a loop ( to run automatically with dimension of X, here 50). How can I do that? Your cooments will be highly appreciable. Alex *# Code:* library(lars) library(chemometrics) X<-matrix(rnorm(2500),ncol=50) dim(X) # [1] 50 50 X1<-X[,2:dim(X)[2]] # I have taken out first column dim(X1) #[1] 50 49 X2<-X1[2:dim(X1)[1],] #

I have been working on a patch to add support for max/min reductions in LoopVectorize. One of the comments that came up in review is that the implementation could be simplified (and less fragile) if max and min intrinsics were recognized rather than looking for compare-select sequences. The suggestion was to change compare-selects into max and min intrinsic calls during instcombine. The

The attached patch makes xenconsole send and receive console messages over a remote connection, instead of via stdin/stdout - if given the --remote switch. It is useful for proxy''ing real console message or other protocol messages (such as gdb) between dom0 and a remote host. We''re currently using it for proxying gdb between gdbstub in a partition that talks gdb over the console

A few people have requested features; I've implemented them in this updated version (attached).

Hi, I wrote a small script in order to stress test llc using test cases generated by llvm-stress. When it finds a case where llc seems to have crashed, it greps the output for Assertion, LLVM ERROR, etc., removes things that look like hex numbers and ID numbers, and then checksums the resulting text. In this way, it can automatically categorize different bugs into different subdirectories. I
