[LLVMdev] a question about constant fold for fdiv
Hello, I have a question about the constant folding for fdiv instructions.
For the instruction "fdiv double 0.0, 0.0", the folded result is inf. I
think this should be nan. Can anyone tell me why it is not nan?
Thanks.
Leo

significance threshold in CCF
Hi everyone,
When the CCF between two series of observations is plotted in R, a line indicating (presumably) the significance threshold appears across the plot. Does anyone know how this threshold is determined (it is different for each set of series) and how its value can be extracted from R? I've tried saving the CCF into an object and unclassing the object, but there's nothing there to

Crossword answers have to be drop-in replacements for the clue in a
sentence. Hence replacing
"She writes in C and R, say."
with
"She codes"
would work, but "She coder" would not.
(If one interpreted C and R as the names of third party candidates for
office, then "She votes" would work,
but the across words made "codes" a more reasonable

I do not understand the question and I do not understand the answer. Possibly one confounds the other.

Well to complicate things, I don't think RULES is the answer.
This is a cryptic crossword clue. They usually contain the answer twice
(well... Cryptically!!)
Writes in C or R, say.
I think the answer is CODER
If you look up the definition of say in the dictionary one option is:
1. give instructions to or direct somebody to do something with
authority (verb)
That's the simple

I think the specification says that it is "undefined" so any value will
do. inf is just as undefined

rsync --delete-existing needed
Hi,
I made the mistake of doing an rsync of a directory into the wrong
destination,
so that the destination became a mix of two directories of unrelated files.
Top unravel the mess, I could need something like a --delete-existing
option.
The semantics would be to delete at the destination ONLY those files that
exists at the
source.
I tried to concoct a combination of options that would do

Newbie needs help
Hello,
I have an old crossword program that runs OK on Win98, WinMe, and XP.
I have installed, via yum, wine and wine-devel and the associated
dependencies on my Fedora 8 system.
I have copied all the files from the program's install floppy to a
directory in my home folder, the same as installing it on XP.
However, when the program tries to access the word files it fails and

Photoshop CS2 Crash under Wine, "Unable to continue because of a hardware or system error. Sorry, but this error is unrecoverable."
I recently came across a post (circa jan-feb 2008) where a user had encountered a fatal and unrecoverable crash when starting Photoshop for the second or subsequent time.
I've noticed that this issue has happened to many people, myself included while installing it on someone's system today, and that, while there is a short-term workaround (noted below), nobody has yet posted an actual

Vectorized forms of isTRUE, identical and all.equal?
Dear all,
I'm wondering if there exist vectorized forms of 'isTRUE()',
'identical()' and 'all.equal()'. My problem is that I wish to test if
each element of a vector is equal to a particular value (or
numerically close), whilst dealing carefully with NAs and so on.
However, using sapply() with identical() is very slow because it makes
so many separate function calls:

You are right yes. The code works faster with <4 x float> types, with still works a bit slower than the scalar
