[LLVMdev] Double spills with Greedy regalloc
Hello,
I noticed the following interesting code sequence while compiling a piece
of code with the backend I'm developing. Probably this issue is for Jakob,
but anyways this is what I'm getting:
STDWPtrQRr <fi#12>, 0, %R25R24; mem:ST2[FixedStack12](align=1)
STDWPtrQRr <fi#12>, 0, %R25R24; mem:ST2[FixedStack12](align=1)

prevent conversion to factors in aggregate?
...39;ve been trying to figure out how to prevent a column that is the result of
an aggregate function call so that I can use it in further calculations. For
example, I would like to aggregate the expf for the data.frame by sp
(character) and dbh (double d=rounded to integer) using the command:
> st2 <- aggregate( ntrs$expf, by=list(sp=ntrs$sp,dbh=ntrs$dbh), sum )
> st2$expf <- st2$x / 20
> st2$basal.area <- st2$dbh^2 * st2$expf

data frame row statistics (mean)?
...o calculate the mean value of each row in a data frame (d),
I am having troubles and getting errors using the code I have written.
Below is a brief example of the code, any thought or suggestions would
be great.
Thank you for your time,

# Example Code:
d <- data.frame(st1=c(1,2,3,4), st2=c(2,5,6,7), st3=c(5,5,NA,7),

avg <- rep(NA,length(d[,1]))

Problem with st driver
Hi ;
I used a scsi tape driver (/dev/st2) on a red hat 7.2 system ia64.
when I rewind first the tape, it is ok
when I write a long file on the tape (dump 0f /dev/st2 /dev/sda3),
dump seems to be ok, but the next rewind operation ( mt rewind )
gives an error message :

and , in the /var/log/messages, I get :

## this one has more fields: how do I generalize the regular expression?

[LLVMdev] Re: recursive structs (linked list)
...mory, which allows users to do pointer comparisons to check
structural equality of types. Naturally, this makes things interesting
when it comes to building recursive structures. :)
The trick to it is to use an Opaque type like so:
// ST1 === struct ST1;
OpaqueType *ST1 = OpaqueType::get();
// ST2 === { int, ST1* }
StructType *ST2 = StructType::get(make_vector(Type::IntTy,
PointerType::get(ST1), 0));
// ST1 === ST2, delete ST1
ST1->refineAbstractTypeTo(ST2);

--partiall-dir not behaving like it ought too
Hi,
I have awaited the new release inorder to use the -"-partial-dir" option.
But after testing it seems that it does not behave like it says on the tin.
It will correctly move and rename the interrupted file to the declared
directory, but it will not
attempt to use it when the client attempts to rsync the file again.
I have a Solaris 8 box running as a server (Matthew), and another
