...volution analysis pass). Is there fundamental functionality missing in the auto vectorizer when the target vector size increases to 512 bits (instead of 128 for example)? And why? What needs to be done (on a high level) in order to have the auto vectorizer succeed on the test function as given erlier?

Maybe you could rewrite the loop in a way that will expose contiguous memory accesses. Is this something you could do ?

Hi Frank, > > To answer Nadav's question. This kind of loop is generated by a scientific library and we are in the process of evaluating whether LLVM can be used for this research project. The target architectures will have (very wide) vector instructions and these loops are performance-critical to the application. Thus it would be important that these loops can make use of the vector

Hello! I have bin trying to set up trunking between some of my Asterisk boxes but had no luck... I use Asterisk 2.0.6 on SuSE 6.2, but I have had the same problem with erlier releases. I have a working connection and can place multiple calls in both direktions. Than I set "trunk=yes" on both sides and reload. "CLI> iax2 show peers" shows a (T) and low latency on both sides. Now it is not possible to get a call trough any more:-( I have working ti...

Since the array access is consecutive over 4 loop iterations I gave it a try and unrolled the loop by...

I''m on Mac OSX and I''m about to rip my hair out over how hard it is to install rails. I''ve installed rubygems and am typing "ruby setup.rb" in the command line and get "No such file or directory." I''ve never had to use command lines before so this is alien to me. Can''t they just make installation GUI-based for non-geeks like
