[LLVMdev] Proposal: "load linked" and "store conditional" atomic instructions
Hi,
I've been looking at improving atomicrmw & cmpxchg code more,
particularly on architectures using the load-linked/store-conditional
model.
The summary is that current expansion for cmpxchg seems to happen too
late for LLVM to make meaningful use of the opportunities it provides.
I'd like to move it earlier and express it in terms of a first-class
pair of "load linked"

glmmBUGS: logistic regression on proportional data
Hello,
I am trying to run a logistic regression with random effects on
proportional data in glmmBUGS. I am a newcomer to this package, and
wondered if anyone could help me specify the model correctly.
I am trying to specify the response variable, /yseed/, as # of successes
out of total observations... but I suspect that given the error below,
that is not correct. Also, Newsect should be a

question about cloud() in lattice package
Hi all,
I have been previously been using scatterplot3d package to create some graphs but unfortunately it does not allow me to rotate the
plot on all three axis. The cloud() function in the lattice package does allow me to do so. When I was using scatterplot3d I was
using a script (Shown Below) to calculate the mean, quartiles and range limits for all three axis and I was representing that on the

ssh-agent does not immediately clean timeouted keys from memory
during my seminar of advanced exploitation techniques (SEAT, [1]) i
developed some methods to crack into system via DMA (e.g. via firewire).
as part of this i developed a program that steals loaded ssh private
keys from ssh-agents. i was astonished to find that the keys are not
immediately removed from the agent when a timeout occurs, but only the
next time the agent is queried via its socket. i

Define a variable on a non-standard year interval (Water Years)
Hello,
I am trying to define a different interval for a "year". In hydrology,
a "water year" is defined as the period between October 1st and
September 30 of the following year. I was wondering how I might do
this in R. Say I have a data.frame like the following and I want to
extract a variable with the water year specs as defined above:

Basically just wanna hold some ui state in a cookie.
Did I miss something obvious ?

predict.lm is broken in 1.1.0-patched (2000-August-7) (PR#626)
predict.lm has been broken by recent changes to the patched branch.
It fails for all singular fits. An example:

data(quine)
quine.hi <- aov(log(Days + 2.5) ~ .^4, quine)
quine.nxt <- update(quine.hi, . ~ . - Eth:Sex:Age:Lrn)

problems with seq.dates
There seem to be a bug in the seq.dates function in the chron package for R
2.0. Please see below:
when the specified frequency is "months", seq.dates does not return the end
of the specified interval all the time:
> seq.dates(from = "05/31/04", to = "12/31/04", by = "months")

[LLVMdev] Assert in LiveInterval update
Hi Lang,
Just one more quick question. in LiveIntervalAnalysis.cpp In
SlotIndex findLastUseBefore(unsigned Reg, SlotIndex OldIdx)
Did you really mean to use
for (MachineRegisterInfo::use_nodbg_iterator
UI = MRI.use_nodbg_begin(Reg),
UE = MRI.use_nodbg_end();
UI != UE; UI.skipInstruction()) {}
Aren't we currently dealing with units,

[LLVMdev] Assert in LiveInterval update
Lang,
I think I am getting closer to understanding this. The findLastUseBefore()
should probably look something like this:
// Return the last use of reg between NewIdx and OldIdx.
SlotIndex findLastUseBefore(unsigned Reg, SlotIndex OldIdx) {
SlotIndex LastUse = NewIdx;
if (TargetRegisterInfo::isPhysicalRegister(Reg)) {

[LLVMdev] Targetting a virtual machine having no registers
Hi *!
I am writing a C compiler to target the Lego Mindstorms NXT virtual
machine. While I was implementing the optimizer and code generator I
realized that it might be useful to use LLVM for this.
The question I have is related to writing a LLVM target for this
architecture. I have read most of the documentation available on the

Server settings for BackgrounDRB?
