TargetData does not have enough information for vectorization. For example, we need to ask the target if it has efficient "cos4" implementation or the cost of 'mult_4xf32'. We need lots of target specific information for deciding when to vectorize and which vectorization optimizations to apply.

Having problems with SSL and Apache on CentOS
I had a RH7.3 box that provided some web services, but the hard drive
recently started to throw errors. So I got another drive and built a
new system using CentOS4. Unfortunately, there is no one to one as far
as Apache since COS4 uses Apache 2 and there is a dramatic difference
in the way the config files are done. I have managed to get it to
recognize the directory on my other drive after finding the selinux
commands to allow that directory to be used. I can get to the startup
page if I go through port 80. I also have it r...

...t with I would like to make sure that I
got the output from (3) right. The ouput of (3) tells me that the highest
R^2 value was reached after 8 iterations and there are only 8 significant
predictors in this model ??? In addition the only significant frequencies
(predictors) left are:
cos1, cos2, cos4, cos7, sin1,sin2, sin3, sin5
I got this information interactively. But I'm in troubles at extracting it
automatically.
Any suggestion ?
Question: Do I have to run "step" in advance of "regsubsets" for a
first-pass model pruning or may I run "regsubsets" on the o...

I agree. Once we make the codegen accessible to the IR-level passes we need to start talking about
