Hi Jay - I see the slow, small accesses using an older clang [Apple LLVM version 7.0.0 (clang-700.1.76)], but this looks fixed on trunk. I made a change that comes into play if you don't specify a particular CPU: http://llvm.org/viewvc/llvm-project?view=revision&revision=245950 $ ./clang -O1 -mavx copy.c -S -o - ... movslq %edi, %rax movq _spr_dynamic at GOTPCREL(%rip),

I'm trying to generate 50+ graphs using the UScensus2000tract data. I need to access the data for just about all of the states, so I was hoping to create a simple loop that will take the relevant state from my data and load the associated census data from the UScensus2000tract package. Below is a sample of what I'm trying to do. Any suggestions are much appreciated.

Thank you for your reply. FWIW, I wrote the .ll by hand after taking the C program, using clang to emit the llvm and seeing the memcpy. The memcpy version that clang generates gets compiled into assembly that uses the large sequence of movs and does not use the vector hardware at all. When I started debugging, I took that clang produced .ll and started to write it different ways trying to get

Yeah, the llvm-ar tests are working on Windows. But I'm getting different results when I try to use the same commands in an LLDB lit test. Maybe there's something messed up in LLDB's local lit config? If I have `mkdir %t/subdir` in my lit test, I get either file-not-found or a complaint about "unrecognized option /subdir." The one-and-only mkdir on my PATH is

Dr. Stevens, Hi, my name is Trey Scott, and I'm a grad student of Brian McCarthy's. He referred me to you because of your expertise in handling complex R problems. We were hoping you could help us solve a nagging problem that is prohibiting me from producing graphicl output. Here is a simple mock-up of the matrix I'm using a b c d e f 1i 1 4

I'm writing a lit test that needs to temporarily make a subdirectory. I tried: ``` // RUN: mkdir %t/subdir ``` But on Windows, it's hard to bypass the built-in mkdir to use a Posix-style one from Git or GnuWin. The built-in mkdir believes the `/subdir` is an unrecognized command flag. I figure I cannot just use a backslash because that would fail on Posix systems. (The test should

Hi everyone, Ive just installed a bunch of Snom 360s, and now having a NIGHTMARE of problems! Ive got a receponist phone with a extra sidecar on it. And when she gets 2+ calls and puts them on hold, when she goes to transfer them out the calls on hold get merged together. Somehow the calls on hold get merged and not to the extension needed!! Any help on this would be great guys, that would be

Realtek is "real" good about getting drivers for their chips into the kernels as soon as possible. They are one of the few vendors that I have never had a problem with built in support... Mike McCarthy On 06/03/2016 08:03 AM, Phil Manuel wrote: > You can get the Linux driver from >

I was hoping this would be the right place to look for some help, I cannot make public folders get the right permissions. I continually get the fchown error in logs, and have googled high an low to find multiple solutions that do not work for me. I'm using maildir. I have sendmail with postfix distributing my mail. I created maildir's in each users personal directory. I then thought

Hello, I am trying to help a colleague with an R problem (see below) to whit I can only generate a very inelegant solution. Any advice would be welcome. Thanks, Brian If you have two matrices, say a species by trait matrix (Matrix 1 below) and a plot by species matrix (Matrix 2 below), is there a straightforward way to prune one matrix so that the species list matches those in a

Hi there! Seems that my 2.0beta5 is not going as smoothly as I'd hoped. We've found a strange behaviour which is only happening when people first log in in the morning. When we log in, a number of drives are mapped to various directories on the Unix box. Things seem to go OK until another person logs in and tries to access a file already open by another user. Then they both seem to

Hi, I have created a dll in Fortran and used the Visual Studio 2005 Compiler. I've read that certain problems can arise based on the compiler used and that these problems can sometimes cause R not to be able to access everything appropriately, but I've not found how to fix any of these problems. Specifically, after using dyn.load, I know the dll has been loaded because it is listed in

[cc'ed back to r-help] I've started to take a look, and there's nothing immediately obvious about the problem with the fit (the warnings and errors are about a "non-positive-definite Hessian", which usually means an overfitted/poorly identified model) -- still working on whether there's a way to get more useful information. As it turns out, glmmADMB's default

I've just upgraded our little network here to 2.0 beta 5. The server is a Data General Intel box running DGUX R4.20. Compile and install went incredibly well and things have just about working straight off. However, we experienced a little 'funny' this afternoon. A user was creating and deleting a postscipt file in a Unix directory. She then used Ghostview on the PC client to

Hi, does anybody have any pointers on where to look to learn how to write custom dynamic templates? Agile is a little sparse on this (but otherwise superb)! Thanx -- Posted via http://www.ruby-forum.com/.

I am a first time poster, so I apologize if this is an obvious question or out of scope for LLVM. I am an LLVM user. I don't really know anything about hacking on LLVM, but I do know a bit about compilation generally. I am on x86-64 and I am interested in structure reads, writes, and constants being optimized to use vector registers when the alignment and sizes are right. I have created a

Hi, Suppose I have the following data name     score Abel        88 Baker      54 Charlie    77 stored a  table called myData. I want to write a function that will create a table which is a subset of myData containing those have a score > 75. I know I can do this with the following command: subset(myData, score > 75) But I would like to do this via a function, something like:
