PPC little endian?
Hi, I am wondering why we dont support PPC32 LE? Here is the output of llvm-mc --version, in which only PPC32, PPC64 & PPC64LE are supported. $ llvm-mc --version LLVM (http://llvm.org/): LLVM version 3.6.2 Optimized build with assertions.

[LLVMdev] Optimization on Atomics (and the OpenMP memory model)
Hi everyone, The OpenMP standards committee has begun work to formalize their memory model, and define its relationship to the C/C++ memory models. A questionnaire has been put together (pasted below), and I'd like everyone's help in composing detailed answers to inform their decision-making process. While our OpenMP support is still in active development, many of these questions apply

libuv bug ??
EPEL package but I think there's a packaging bug, thought I would ask here. Trying to build something that requires libuv-devel - it finds the .so but can't determine version. header files are in /usr/include/uv however the pkgconfig file specifies /usr/include as the include directory. The pkgconfig file also has the version so I'm not sure why the make file can't determine

Error in ifelse(append, "a", "w") : , (list) object cannot be coerced to type 'logical'
Hello I will appreciate your help with the following. Running a script in R 2.14.1 under windows vista I get the following error message: Error in ifelse(append, "a", "w") : (list) object cannot be coerced to type 'logical' However, the very same script runs perfectly well under Ubuntu. My understanding is that this type of error is associated to

use ggplot in a function to which a column name is given
Hi everyone, Hi ggplot users in particular, ggplot makes it very easy to plot things given their names when you use it interactively (and therefore can provide the names of the columns). qplot(x,foo,data=A) where A has columns (x,y,foo,bar) for example but I would like to use this from inside a function to which the name of the column is given. I cannot find an elegant way to make this

procrustes (vegan) plot of residual differences
Hello This is a simple question but I couldn't google an answer. In the procrustes function of the vegan package, one uses plot(procrustes_object, kind=2) to obtain a plot of the residual differences. For instance: data(varespec) vare.dist <- vegdist(wisconsin(varespec)) library(MASS) mds.null <- isoMDS(vare.dist, tol=1e-7) mds.alt <- isoMDS(vare.dist,

[PPC] Linker fails on -fstack-protector
I found a bit weird to use address space for this, since the offset of getting stack_guard in TCB is, unfortunately, negative: https://github.com/gcc-mirror/gcc/blob/master/gcc/config/rs6000/linux64.h#L610 In my understanding an address space is referring to a segment register (-on powerpc 32bit; or SLB entry on powerpc 64bit?) with a non-negative offset value, so that it's actually accessing

“For” calculation is so slow
Dear All, The function I wrote can run well with the small data, but with the large data, the function runs very very slowly. How can I correct it? Thank you very much. My function as below: a<-c(1:240) b<-c(1:240) l=function(a,b){ v=0 u=0 uv=0 v[1]=0 u[1]=0 uv[1]=0 for (i in 1:(length(s)-1)){ v[i]<-((gx[[i]][b,(gx[[i]][a,1]+1)])-(gx[[i]][a,gx[[i]][a,1]+1]))/(gx[[i]][a,gx[[i]][a,1]+1])

[PATCH v4 0/2] s390: virtio: let arch validate VIRTIO features
Hi all, I changed the patch subject to reflect the content, becoming more general. 1) I removed the ack from Christian and Jason even far as I understand they gave it for the functionality more than for the implementation. @Jason, @Christian, please can I get back your acked-by with these changes? 2) previous patch had another name: [PATCH v3 0/1] s390: virtio: let arch choose to
