RFC: Combining Annotation Metadata and Remarks
Hi,
I would like to propose a new !annotation metadata kind that can be attached to arbitrary instructions to drive generating remarks that provide additional insight into transformations applied to a program.
To motivate this, consider these specific questions we would like to get answered:
* How many stores added for automatic variable initialization remain after optimizations? Where are

RFC: Combining Annotation Metadata and Remarks
Cool! I really like the idea. I left a comment about metadata
preservation below.
Once this is available we will certainly employ it to understand OpenMP
programs better.
We could also think about a user facing version of this while we are at
it ;)

Roaming Profiles -- Problem Rapidly Switching Users
Does anybody have any insight into what could be causing this strange
problem? I have Samba 3.02 (sorry, can't upgrade right now). My Linux box is running
Mandrake 10 Official. I have Samba configured as a PDC.
I can successfully add machines to my Domain -- and log on as ANY user from
ANY machine. However on a SINGLE MACHINE, when I log on as USER_1 and access

Sum per hour
Dear all,
I have a list of precipitation record and a list of time
I would like to sum them up per hour, or per day.
Does such a function exist ?
example:
time<-c("2000-10-03 14:00:00","2000-10-03 14:10:00","2000-10-03

Creating a correlation Matrix
Hi all:
I have a question on how to go about creating a correlation matrix. I have
a huge amount of data....21 variables for 3471 times. I want to see how
each of the variables correlate to each other. Any help would be
appreciated, including which package and which functions I should use to do
this.
Thanks,

regular expression for na.strings / read.table
Dear all,
I am working with a csv file.
Some data of the file are not valid and they are marked with a star '*'.
For example : *789.
I have attached with this email a example file (test.txt) that looks like
the data I have to work with.
I see 2 possibilities ..thast I cannot manage anyway in R:
1-first & easiest solution:
Read the data with read.csv in R, and define as na strings

How to get optimization remarks while testing with lnt in llvm
Hi, I'm new to llvm and am trying to run benchmarks from the test-suite
using lnt to check loop-vectorization for various benchmarks.
Test are compiling and executing fine, but I am not getting optimization
remarks while using flags like -Rpass-missed=loop-vectorize and
-Rpass-analysis=loop-vectorize
I've tried running it like this:

error message when downloading packages using the OS X shell
Hi Fellow R Users,
I recently upgraded to Mac OS X 10.5 (Snow Leopard) and had some issues
downloading and running R 2.10.1. I fixed the tcl/tk problem I was
originally having but it was replaced with another. I run R out of the shell
(terminal) and when I ask it to download.packages() it gives me the
following message:

Next steps for optimization remarks?
Adam, thanks for all the suggestions!
One nice aspect of the `-Rpass` family of options is that I can filter
based on what I want. If I only want to see which inlines I missed, I could
use `clang -Rpass-missed="inline"`, for example. On the other hand,
optimization remark YAML always include remarks from all passes (as far as
I can tell), which increases the amount of time it takes

[RFC] Interprocedural MIR-level outlining pass
Hi Violeta,
I compiled with
clang -Oz and
clang -Oz -mno-red-zone for comparisons against Oz
and
clang -O0 and
clang -O0 -mno-red-zone for comparisons against a default clang.
I unfortunately don’t have the clang commit I worked with on my home laptop, and don’t have access to the computer I was using at Apple, so I can’t help you there.

Dear R user,
After I imported data (csv format) in R, I called it out. But it is in
non-numeric format.
Then using "as.numeric" function.
However, the output is really awful !!!!!

Optimization remarks for non-temporal stores
Hi,
There was a recent discussion on generating non-temporal stores automatically[1]. This is a hard problem to get right. What seems like a much easier but still useful problem to solve is to provide diagnostics to the user where NT stores *may* help. Then the user can add the corresponding builtins and see if they are beneficial.
My hope is that with the work to add profile-driven

Help with assigning a value based on existing numbers
Hi All
I have a column/variable called time difference. It has a whole list of
numbers from 0 through to the hundreds eg 236. I want to assign a

less, 1 -2 months, 2-3 months etc
So the result would look something like:

Good afternoon!
After applying the latest bash RPM listed at

Showing hotness in LLVM optimization remarks using AutoFDO sampling profile data?
Hello!
(+cc Adam Nemet, since he presented on optimization remarks at LLVM Dev Mtg
2016)
I have a large C++ program, which I am compiling using a sampling profile
generated via perf and AutoFDO. I'd like to use this profile in order to
show the hotness of each code path that is displayed in the new
optimization remarks viewer tool (
https://www.youtube.com/watch?v=qq0q1hfzidg).
