[LLVMdev] vmkit on x86_64
Hello,
I'm trying to compile vmkit on a x86_64 linux box with gcc-4.1.2, but
I'm running into troubles because of various problems with casts
between pointers and integers. Is there anybody who succeeded in this
task? Az I see, some of the problems can be fixed with an appropriate
typedef/macro declaration, but in VMCore/JavaObject.cpp some lowlevel
bitmanipulation is used, to mark

How to use conditional statement
Dear R helpers
Suppose
val1 = c(10, 20, 35, 80, 12)
val2 = c(3, 8, 11, 7)
I want to select either val1 or val2 depending on value of third quantity val3.
val3 assumes either of the values "Monthly" or "Yearly".
If val3 = "Monthly", then val = val1 and if val3 = "Yearly", then val = val2.
I tried the ifelse statement as

[LLVMdev] vmkit on x86_64
Hi Zsombor,
Thanks for the patch! Unfortunately I can't apply it because the llvm
API has moved from BinaryOperator::create to BinaryOperator::Create. Are
you using svn head?
Now on the x86_64 part. There has been very little work on porting vmkit
on x86_64. If you're having compilation problems, I suppose it's in the
garbage collector directory (GCMmap2). If you could make the

Memory Store/Load Optimization Issue (Emulating stack)
Hello,
I am trying to emulate the "stack" as like on x86 when using push/pop so
afterwards I can use LLVM's optimizer passes to simplify (reduce junk) the
code.
The LLVM IR code:
define { i32, i32, i32 } @test(i32 %foo, i32 %bar, i32 %sp) {
; push foo (On "stack")
%sp_1 = sub i32 %sp, 4
%sp_1_ptr = inttoptr i32 %sp_1 to i32*
store i32 %foo, i32* %sp_1_ptr, align

Barplot with lines
Hi,
I'm trying to plot stacked barplot with lines on it. Here is the data.
emp days val1 val2 score
1 21 1 0 1200
2 35 1 1 na
3 42 na na 3000
4 53 2 1 2100
5 64 1 0 na
6 73 na na 1400
My X-axis is days. I'm looking to plot val1,val2 as stacked bars and score
as lines with different y-axis. I could get the bar plot and lines on it
but the problem is the bars and lines are not aligning

Memory Store/Load Optimization Issue (Emulating stack)
Thank you for the hint.
I adjusted the code and it works:
The code after replacing inttoptr with getelementptr:

entry:

%sp_1 = getelementptr i8, i8* %sp, i32 -4
%sp_1_ptr = bitcast i8* %sp_1 to i32*

preparing data for barplot()
What is the best way to produce a barplot from my data? I would like
the barplot to show each person with the values stacked
val1+val2+val3, so there is one bar for each person When I use
barplot(data.matrix(realdata)), it shows one bar for each value
instead.
To post here, I created an artificical data set, but it works fine.

Hi,
I have data like this....
print(x)
ID VAL1 VAL2
1 B A
2 P Q
3 T S
What I would like is data like this...
ID VAL1 VAL2
1 A B
2 P Q
3 S T
So that VAL1 and VAL2 are alphabetically ordered.
Any advice is welcome!

Memory Store/Load Optimization Issue (Emulating stack)
Thanks for the answers. Although I am not sure if I've understood the docs
about how inttoptr/ptrtointr are different when compared to gep.
It says: "It’s invalid to take a GEP from one object, address into a
different separately allocated object, and dereference it.".
To go back to my intention why I am doing this, I would like to "emulate"

lattice panel question
Dear R users,
How to change lattice panel label/text from the automatically generated
label (based on the conditioning) to our own set of label?

= 25),

Memory Store/Load Optimization Issue (Emulating stack)
Hi again,
So I finally gave up on trying to get through the converting (x86' push pop
mov add) because it deals a lot with crazy pointer arithmetics and sonce
inttoptr and ptrtoint doesn't provide any alias analysis information.
Daniel, you said it doesn't make much sense to provide it but in my cases
it is actually very much needed, you didn't say it wasn't possible to

Getting group size in a data frame
Hi all,
I have a data frame with some measured values of some animals. Sometimes the
measurement failed, resulting in a NA for a measurement and sometimes the
animal died, resulting in NA for all measurements.
I have several groups of animals. How do I find the size of each group with
only alive animals? And how do I find the size of the groups for each
measurement?

Aggregating a List
Hi all,
There must be a really obvious R solution to this, but I can't figure out
how to aggregate a list. For instance, if I read.table the following from
a file:
Val1 Val2
A 3 4
A 5 6
B 4 4
I would like to take the mean (or median) across any/all rows of type "A"
to end up with the structure:
Val1 Val2
A 4 5
B 4 4
in this case. How would I go about doign that w/o doing a

I am wondering if a joining "one-to-many" can be done a little bit easier. I tried merge function but I was not able to do it, so I end up using for and if.

2 problems with latex.table (quantreg package) - reproducible
Dear all,
When using latex.table from the quantreg package, I don't seem to be able to set
table.env=FALSE: when I don't specify caption (as I think I should, when
understanding the R help rightly(?)), I get an error message, and when I
do so, of course I get one, as well.
The funny thing is, that a table is indeed produced in the first case,
so I get a nice tabular, but as I'm using

[DebugInfo] [DWARFv5] .debug_abbrev contents for different implicit_const values
Hello all, it looks like we have a bug here but I am not sure. Currently
if we have two similar types with implicit_const attributes and
different values we end up with only one abbrev in .debug_abbrev
section. For example consider two structures: S1 with implicit_const
attribute ATTR and value VAL1 and S2 with implicit_const ATTR and value
VAL2. The .debug_abbrev section will contain only 1

[RFC, PATCH 17/24] i386 Vmi msr patch
Fairly straightforward code motion of MSR / TSC / PMC accessors
to the sub-arch level. Note that rdmsr/wrmsr_safe functions are
not moved; Linux relies on the fault behavior here in the event
that certain MSRs are not supported on hardware, and combining
this with a VMI wrapper is overly complicated. The instructions
are virtualizable with trap and emulate, not on critical code
paths, and only
