Capturing Function Arguments
I'm wrapping a function in R and I want to record all the arguments
passed to it, including default values and missing values. I want to
be able to snoop on function calls in sourced scripts as part of a
unit testing framework.
I can capture the values fine, but I'm having trouble evaluating them
as if `force()` had been applied to each of them.
Here is a minimal example:

load instruction erroneously removed by GVN v2
Hello to whom this may concern,
Versioned this as I saw identical title before. I'm compiling a clang
project where I'm seeing GVN mess up and replace a load with a wrong def
value. I am using LLVM-3.5, but the problem has been observed upto 3.8.
To illustrate the problem,
define i32 @main
scalar.ph:
<initialize [80 x i16] %dest>

Unable to mount loopback devices in RAID mode
Hi!
I recently tried to mount a filesystem in RAID1 mode using loopback devices. I followed the instructions at [1]. Here''s exactly what I''ve done:

$ dd if=/dev/zero of=raid1_1.img bs=1M count=500
$ mkfs.btrfs -m raid1 -d raid1 raid1_0.img raid1_1.img

load instruction erroneously removed by GVN v2
Thanks for quick reply Daniel,
I tried to make a simple C testcase, but could not reproduce the same
condition with output from Clang. I suppose I could modify the C code to
make it look similar with TBAA's; I may be able to provide this by eod.

My mistake; I was referring to the store $lcssa in bb2. Looking at the C
source code, it should definitely alias

syslinux installation problem
Hey, guys.
I have a problem when installing syslinux 4.06, and I'd be grateful if someone could tell me how to solve the problem.

I still have it in my mailbox: ADY4UEFI.IMG in ADY4UEFI.ZIP.
The test results are the same as with Didier's partition image.
Wrapped in an ISO and presented as -cdrom it reboots in cycles.
Presented as -hda it boots as naked disk image and as part of

Samba clients can't see partitions mounted via loop device from image files
Is there something special about filesystems mounted via
the loop device, which prevents Samba from sharing them?
I have a small LAN with several PCs on it. It has a
few Windows machines, and a Linux machine running
Mandrake 10 (kernel 2.6.3), which shares out its root

img file to physical disk
Hi all.
I''ve got a domU that exists in a sparse file image, I''d like to now use
this on a physical partition (loopback performance issues).
Is there an a easy way to do this ?
Thanks

how to mount a xen image file
Can someone correct my attempt at mounting a xen image?
Im trying 2 things:
a)

which dmesg|tail tells me is Not an NTFS system
b) ntfsmount ./mywindows.img /media/loop -o force
which gives me mywindows.img invalid argument

[LLVMdev] Missed vectorization opportunities?
Hi,
I am trying to understand the limitations of the current vectorizer, and came upon these test cases that fail to get vectorized.
1. loop1 below (note the increment by 2) fails to get vectorized because the access a[j+1] is considered to wrap around (the corresponding SCEV doesn't have nsw/nuw set) and hence isStridedPtr() in LoopAccessAnalysis.cpp return false.

Syslinux + integrated flash disk
Quick summary: Syslinux stops at "Boot failed". Which, from a quick look at
the raw disk image, seems to indicate that the boot sector loads but it fails
to load the .sys loader.
The details: I've been trying to load Linux (or etherboot...or anything at all
that is not NT embedded) into a set of Compaq Evo T20 48/64 for a while now.

Using LVM snapshots to backup NTFS partitions for windows guests
Hi everyone!
I''ve been reading this list for a while and I''m thinking that the best
way to do backups is using LVM snapshots as discussed here several
times.
The problem is that when i use a LVM logical volume as windows disk,
windows writes the partition table onto the LV so the LV itself is not
a partition - it''s a whole disk.

I think you meant panel.first, not plot.first. At least I cannot find
any mention of plot.first in the R source code. In this example,
