I can't find any benefit unrolling this loop.

Hi, you need to run some optimization passes first. (like -O2)

Who's eating our bandwidth?
Hi,
I've recently setup a new server for our public libraries. For the last
two years, this has been my first "big" job, since it involves
networking eleven small to medium size public libraries.
There was a hiccup some time ago when the administration hiring me
wanted to do it on their own, but it took them less than two weeks to
get the server hacked and lose everything. So

I just want to try loop-unroll and see corresponding changes in the bitcode
file. For that any loop will do. Have you been able to test llvm loop-unroll

Dream of a wiki GUI for R
Dear R fans ( and wiki fans),
I am just writing a draft to introduce confidence intervals of various
"effect sizes" to my students. Surely, I'll recommend the package
MBESS in R. Currently, it means I have to recommend R's interface at
first. As a statistics teacher in a dept of psychology, I often have
to reply why not to teach SPSS. Psychologists and their students hate

base::order making available retGrp and sortStr options for radix method?
Hi together,
a bit more than a month ago I have released the 'collapse' package for
advanced and fast data transformation in R with an array of fast grouped
and weighted functions and facilities for efficient grouped programming in
R.
As I am preparing the next update of this package I have come across the
following: For grouping, 'collapse' uses the function 'GRP', and

The function cummax() seems to have a bug.
Hi,
The function cummax() seems to have a bug.
> x <- c(NA, 0)
> storage.mode(x) <- "integer"
> cummax(x)
[1] NA 0
The correct result of this case should be NA NA. The mistake in [
https://github.com/wch/r-source/blob/trunk/src/main/cum.c#L130-L136] may be
the reason.

Latest R-devel build failing on OS X
Ah, got it. For some ancient reason config.site on that machine had
LDFLAGS=-L/usr/X11R6/lib
in config.site, and that prevented configure from inserting -L /usr/local/lib, so linked /usr/lib/libreadline.dylib, which is the Apple-supplied one, which possibly is really libedit...
