paravirtualized vs HVM disk interference (85% vs 15%)
Hi,
We have found that exist a huge degradation in performance when doing I/O to a disk images contained in single files from a paravirtualized domain and from an HVM at the same time.
The problem was found in a Xen box with Fedora 8 x86_64 binaries installed (Xen 3.1.0 + dom0 Linux 2.6.21). The test hardware was a rack mounted server with two 2.66 Ghz Xeon X5355 (4 cores each one, 128 Kb L1

I don't know about Tanu, but we can certainly use this in finding bugs
in LLVM! This has been listed as an "open project" for a long time [1],
but someone already implemented it, saving us the time and effort.
Thanks for the link!

[LLVMdev] [GSoC 2014] Using LLVM as a code-generation backend for Valgrind
Hi,
I've seen on the LLVM's Open Projet Page [1] an idea about using LLVM to
generate native code in Valgrind. For what I know, Valgrind uses libVEX
to translate native instructions into a bitcode, used to add the
instrumentation and then translated back to native code for execution.
Valgrind and LLVM are two tools that I use nearly every day. I'm also
very interested in code

Sounds great! I'll add it to the list of supported platforms.

Tanu,
You've seen ? :-

Don't know whether it is applicable to what you are trying to achieve but I thought I should point it out in case it is useful to you and you have not seen it.

[LLVMdev] Google SOC - Idea
Hi,
I noticed that LLVM had signed up as a mentoring organization for
Google's summer of code. LLVM looks like an exciting project that
overlaps some of my interests.
I would be interested in developing an additional front end for a
language it does not currently support (I'm open to what language). I
do not know much about what this entails in regards to what LLVM
requires from its

I would try that ..Thanks
Another thing that I want to do is to randomize functions within a program (or file ), whatever is easier to do in llvm .Also please tell me how can I randomize global variables ?
Thanks

PE disassembler for unix
Hello, I'm looking for a disassembler to examine a malicious
Win32 binary on FreeBSD. Does anybody have any favourites?
I see pedisassem in ports, but it looks to be broken and unmaintained
(it crashes with a floating point error, currently).

w32dasm - Windows Disassembler 32 - works, please update docs
According to http://www.winehq.com/site/docs/winedev-guide/wine-debugger
"It seems that Windows Disassembler 32 currently has problems working
correctly under Wine, so use IDA or GoVest."
I tried it anyway, and it looked ok while it was disassembling my program.
But then, when it finished disassembling, the window was made really
tiny, and when I made the window regular-sized, the font

Problems using LLVM as a disassembler.
Hi,
I have been trying to use LLVM as a disassembler, thus providing a
small part of my decompiler that I am working on.
It currently decompiles from X86_64 binary.o -> LLVM IR.
It works with a small set of test programs so far, so cannot currently
handle large binary programs yet.
The problem is with the LLVM "getInstruction()" method.
It used to have a PC (program counter)

[LLVMdev] Disassembler status
Hi there.
I've looking libcpu project and some history of the mailing list and got a
question: what is the status of the disassembler? I mean, is there someone
working on it, what targets does it support and so on.
I mean, it would be interesting to be able to "undo" the operations LLVM
does, like machine code->LLVM IR.
If there's no one working with this right now, I'd

[LLVMdev] ARM disassembler
Other than the x86 disassembler effort, is there an ARM disassembler effort
going on? It seems that there have been commits for weeks with messages like
"add so-and-so instruction to ARM.td for disassembly purposes only"...

[LLVMdev] Fix wrong x86 inst encoding / problem with disassembler
Hello
I think I found a bug in the x86 instruction definition file, while trying
out the disassembler.
It looks like the "ADD32rr_alt" instruction should have GR32 operands, not
GR16.
Attached you can find a patch, which should fix the problem.
But even with the change I can not decode e.g. "0x03 0xC1" (should be
"addl %ecx, %eax") only if I remove the

[LLVMdev] MC to LLVM disassembler?
I'm wondering if anyone is working on a machine code -> LLVM bitcode disassembler? Obviously, there won't be a one-to-one correspondence but it seems like you should be able to get close. There's always inline asm for the remaining fragments.
So is there such a thing?
Thank you,

[LLVMdev] x86 disassembler: if-statement with redundant branch
Hi there!
In the x86 disassembler I noticed an if-statement with a
duplicated branch. Are these intended to be identical?

[LLVMdev] x86 disassembler rejecting valid code
Hi,
The x86 (32-bit) disassembler can't disassemble any of the following:
0x2b 0xc9
0x8a 0xc8
0xdd 0x04 0x24
These are:
subl %ecx, %ecx
movb %al, %cl
fldl (%esp)
I've attached patches to bug#8873 which fix all these issues, but I'm not
confident that I've fixed them the right way.
The first two problems are caused by the instructions setting
