Ok, sorry, those were the ones I was referring to: @llvm.arm.neon.* intrinsics.
Is it polluting too much to add the few last (llvm.arm.neon.vadd,
llvm.arm.neon.vsub)? It makes it a bit easier to generate neon

[LLVMdev] Vectorization of pointer PHI nodes
Renato, can you post the c code for the function and the assembly that gcc produces?
Your initial example could be well handled by vectorization of strided loops (and the mentioning of VLD3(.8?)/VST3(.8?) lead me to assume that this is what happened). But the LLVM-IR you sent has a store of 0 in there ;) and strides by 4.
Thanks,
Arnold

[LLVMdev] Vectorization of pointer PHI nodes
This is almost ideal for SLP vectorization, except for two problems:
1. We have 4 stores to consecutive locations, but the last element is the constant zero, and not an additional SUB. At the moment we don’t have support for idempotence operations, but this is something that we should add.
2. The values that we are subtracting come from 3 loads. We usually load 4 elements from memory, or

Getting the correct factor level as Dunnett control in glht()
Hello all,
I would like to do a Dunnett test in glht(). However, the factor level I
want to use as the control is not the first.
dunn1<-glht(model3, linfct = mcp(Container = "Dunnett"), alternative =
"less")
The factor container has 8 levels, so it would be nice not to manually
enter in all of the contrasts. I originally discovered glht() when
working with a glm model

[arm, aarch64] Alignment checking in interleaved access pass
Hi,
As a follow up to Patch D23646 <https://reviews.llvm.org/D23646>, I'm
trying to figure out if there should be an alignment check and what the
correct approach is.
Some background:
For stores, the pass turns:
%i.vec = shuffle <8 x i32> %v0, <8 x i32> %v1,
<0, 4, 8, 1, 5, 9, 2, 6, 10, 3, 7, 11>
store <12 x i32> %i.vec, <12 x i32>* %ptr

[arm, aarch64] Alignment checking in interleaved access pass
Hi Renato,
Thank you for the answers!
First, let me clarify a couple of things and give some context.
The patch it looking at VSTn, rather than VLDn (stores seem to be somewhat
harder to get the "right" patterns, the pass is doing a good job for loads
already)
The examples you gave come mostly from loop vectorization, which, as I
understand it, was the reason for adding the

creating a factor from dates by subject?
Dear R-help,
I have a data set consisting of measurements made on multiple
subjects. Measurement sessions are repeated for each subject on
multiple dates. Not all subjects have the same number of
sessions. To create a factor that represents the session, I do
the following:
data <- read.csv('test-data.csv') # data appended below
data$date <- as.Date(data$date,

I suspect that xapian-compact.cc (and quartzcompact.cc if you can be
bothered) will also need fixing since they use off_t. You need to make
