[LLVMdev] Does loop vectorizer inquire about target's SIMD capabilities?
Hi Akira!

Yes, it uses a cost model to determine the profitability of vectorization. At the moment only x86 provides the necessary hooks that are needed for calculating the costs. We may need to change the cost defaults to

The loop vectorizer is now enabled by default.

I thought that was just a temporary arrangement to get the feel for it, not
to actually have it on all the time (next release). Is it just for -O3 or
lower too?
This can cause problems, for instance on ARMv7, the default is that NEON is
present, but Tegra2 doesn't

[LLVMdev] predicates vs. requirements [TableGen, X86InstrInfo.td]
I tried to add an 'OptForSize' requirement to a pattern in X86InstrSSE.td,
but it appears to be ignored. However, the condition was detected when
specified as a predicate.
So this doesn't work:
def : Pat<(v2f64 (X86VBroadcast (loadf64 addr:$src))), (VMOVDDUPrm addr:
$src)>,
*Requires<[OptForSize**]>*;
But this does:
* let Predicates = [OptForSize]

KNL Vectorization with larger vector width
Thank You.
But I cannot find your mentioned function
LoopVectorizationCostModel::computeFeasibleMaxVF(bool
OptForSize, unsigned ConstTripCount). I am using LLVM 4. I have been trying
to get the required code portion in LoopVectorize.cpp file. But I am unable
to debug this. each time i debug it, it returns me vectorized IR in gdb.
My goal is simple when i mention my target name in opt it should

inquire
I am looking for the binary rw1051. I have some code that will only run in version 1.5.1 and I need to install the old binary code. Is there a repository for previous R versions?

inquire a statistical terms
Dear all,
Is there any standard statistical terminology describing the points beyond
a confidence region? Obviously, the "outlier" is improper here. Please help
me if you happens have the info.
Thanks you very much for your kindly help.

LVM and Backups
Hey there,
I'm testing LVM snapshot to make backups and I've some questions about
snapshot lvm.
In my test case I have httpd, postgresql db and a dataset on a VM.
Running a backup I follow this steps:
1) Stop httpd
2) Create lvm snapshot on the dataset
3) Backup database
4) restart httpd (to avoid more downtime)
5) mount the snapshot and execute backup
6) umount and remove the snapshot
