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>

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.
> store %ptr above the load.
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.
My task - to install the bootloader on the virtual machine image. The image contains the MBR and the only partition with the file system ext4. The file system contains all the files for the guest OS.

[LLVMdev] nested function's static link gets clobbered
Fellow developers,
I'm parallelizing loops to be called by pthread. The thread body that I pass
to pthread_create looks like
define i8* @loop1({ i32*, i32* }* nest %parent_frame, i8* %arg)
parent_frame is pointer to shared variables in original function

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.
What I finally managed to do is using the

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

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

[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.

extlinux and block loopbacks
Hello--
I'm trying to use extlinux to make a bootable disk image, but I've hit

device (/dev/loop1 on the host) and chrooted into it in order to run
