Constant propagation: %sum = add <N x float> %a, %b @llvm.reduce(ext <N x double> %sum) if %a and %b are vector of constants, the %sum also becomes a vector of constants. At this point you have @llvm.reduce(ext <N x double> %sum) and don't know what kind of reduction do you need. - Elena -----Original Message----- From: Renato Golin [mailto:renato.golin at linaro.org]

This is required in order to build using the built-in assembler in clang. --- I squashed the two changes since it would break the normal gcc build otherwise. --- celt/arm/arm2gnu.pl | 2 ++ celt/arm/celt_pitch_xcorr_arm.s | 18 +++++++++--------- 2 files changed, 11 insertions(+), 9 deletions(-) diff --git a/celt/arm/arm2gnu.pl b/celt/arm/arm2gnu.pl index eab42ef..5c24758 100755 ---

Hi All, Since I continue to base my work on top of Jonathan's patch, and my previous Ne10 fft/ifft/mdct_forward/backward patches, I thought it would be better to just post all new patches as a patch series. Please let me know if anyone disagrees with this approach. You can see wip branch of all latest patches at https://git.linaro.org/people/viswanath.puttagunta/opus.git Branch:

Hi Timothy, As I mentioned earlier [1], I now fixed compile issues with fixed point and resubmitting the patch. I also have new patch that does intrinsics optimizations for celt_pitch_xcorr targetting aarch64. You can find my latest work-in-progress branch at [2] For reference, you can use the Ne10 pre-built libraries at [3] Note that I am working with Phil at ARM to get my patch at [4]

Hi All, I've been successfully using the with function for analyses and the transform function for multiple transformations. Then I thought, why not use "with" for both? I ran into problems & couldn't figure them out from help files or books. So I created a simplified version of what I'm doing: rm( list=ls() ) x1<-c(1,3,3) x2<-c(3,2,1) x3<-c(2,5,2)

Hi! I will calculate sum??s in the following way: E.g.: a <- rpois(100,20) b <- rpois(100,5) x <- data.frame(cbind(a,b)) # the sum??s should be calculated based on a. attach(x) sort.nace <- unique(sort(x[,1])) sum1 <- matrix(ncol=1, nrow=length(sort.nace)) # I calculate the sum of all values of b, which have the same category in a. Eg.: sum1[1,] <- sum(subset(x,

Hi All, As per Timothy's suggestion, disabling mdct_forward for fixed point. Only effects armv7,armv8: Extend fixed fft NE10 optimizations to mdct Rest of patches are same as in [1] For reference, latest wip code for opus is at [2] Still working with NE10 team at ARM to get corner cases of mdct_forward. Will update with another patch when issue in NE10 gets fixed. Regards, Vish [1]:

Hi All, Changes from RFC v2 [1] armv7,armv8: Extend fixed fft NE10 optimizations to mdct - Overflow issue fixed by Phil at ARM. Ne10 wip at [2]. Should be upstream soon. - So, re-enabled using fixed fft for mdct_forward which was disabled in RFCv2 armv7,armv8: Optimize fixed point fft using NE10 library - Thanks to Jonathan Lennox, fixed some build fixes on iOS and some copy-paste errors Rest

Hello Timothy / Jean-Marc / opus-dev, This patch series is follow up on work I posted on [1]. In addition to what was posted on [1], this patch series mainly integrates Fixed point FFT implementations in NE10 library into opus. You can view my opus wip code at [2]. Note that while I found some issues both with the NE10 library(fixed fft) and with Linaro toolchain (armv8 intrinsics), the work

Simple question... I would like to dump some summries of lm()'s to small seperate text files. I have looked at: print(), but it don't support output to file cat(), but it claims that 'sum1' is a list write, but that just uses cat()... The script goes something like this: ... lmMax <- lm(NUMAMMON ~ YYYY*MM*DD) sum1 <- summary(lmMax) # help needed here... how to dump sum1

I am having the following error in my function function(theta,reqdIRR) { theta1<-theta[1] theta2<-theta[2] n<-length(reqdIRR) constant<- n*(theta1+theta2) sum1<-lapply(reqdIRR*exp(theta1),FUN = sum) sum2<-lapply(exp(theta2 - reqdIRR*exp(theta1)),FUN = sum) sum = sum1 + sum2 log.fcn = constant - as.numeric(sum) result = - log.fcn return(result) } *error :

Greetings. For R gurus this may be a no brainer, but I could not find pointers to efficient computation of this beast in past help files. Background - I wish to implement a Cramer-von Mises type test statistic which involves double sums of max(X_i,Y_j) where X and Y are vectors of differing length. I am currently using ifelse pointwise in a vector, but have a nagging suspicion that there is a
