[LLVMdev] [GSoC] Improvent of PRE in LLVM compiler
Greetings,

I am Aradhya Biswas, final year student of Computer Science and Engineering

Active DNS registration on join realm?
Dear Samba members,
I am wondering if on joining a realm (with security=ADS), samba 3.x server
gets automatically registered with MS Dynamic DNS server. My test with Samba
3.0.14a on linux did not reveal any such capability. But may be because I
did not use the correct option? I would appreciate any help.
Thanks in advance,

Re: Grant-table error messages in a crash log
Hi Team,
For a XenServer (5.6 sp2) crash I have got following in the crash logs. Can somebody tell me why I can see(grant_table.c:1408:d0 dest domain 40 dying) this and how I can resolve it, if it is an issue.

I don't have cycles for this right now, but if you file a bug I can
give this a shot when I have time later. Even in the best case this
will have to at least wait until end of April because I'm leaving for

missing simplification in ScalarEvolution?
Hi Sanjoy,
Thanks for the reply!
Your approach sounds good to me!
I think 1) is legal as address wraparound in unsigned range doesn't make sense given a positive offset, but I am not sure.
I think umax will not be added if we can prove the predicate as known.
I am not sure whether umax will get simplified if we add nuw to the expressions.

Thanks for the reply!
Would it be possible for you to implement this?
You know the codebase better than I do.

Nested VM
Hello,
As part of my project for my MSc, I am looking for a solution to implement
nested virtual machines. My current scenario is:
- I have a server with AMD Phenom II X6 1100T and 8GB RAM - virtualization
enabled at BIOS.
- I have installed 64bit CentOS-5.6 with Xen enabled (let''s call it as
base1).
- On top of base1 I have also installed 64bit CentOS-5.6 (guest1) with Xen
enabled and

valid BasicAA behavior?
Hi Hal,
In that case what is the best way to query whether there is a loop carried dependence between B[j] and A[j] at i-loop level?
We were operating under the assumption of 'conservatively correct' behavior of alias analysis in the function scope?
Thanks,
Pankaj

[SCEV] inconsistent operand ordering
Thanks for the helpful reply!
I see that we are trying to keep ScalarEvolution stable around instruction ordering. My suggestion would be to not restrict the fix by only recursing on the first operand.
By "dominator logic" I meant that if all other 'cheap' checks fail, we should decide by walking the dominator tree to see which instruction's basic block is encountered

[LLVMdev] collect end line number for scope
Pankaj,
If you want to decorate MachineInstrs then for the end of scope you're not looking at "}" but instead you're looking at _last_ machine instruction in that scope. Now, if you want to find out start and end MachineInstrs for a lexical scope (and corresponding line numbers) then see CodeGen/LexicalScopes pass. It collects lexical scope information and maps MIs to respective

Error of building dom0 kernel
Hi all,
I follow instructions(http://wiki.xensource.com/xenwiki/XenParavirtOps) to
build XEN and dom0 kernel. Building XEN has no problem, but there is an
error which I cannot solve to build dom0 kernel. The brief instructions for
building dom0 are get linux-2.6-xen code from git and make ARCH=x86_64
menuconfig, finally generate kernel.deb. (I did every step exactly as the
web page says)

[LLVMdev] collect end line number for scope
Hi,
The link and the information shared was helpful.
I will make my problem definition more clear.
While I am "asm printing" target code, I also want to emit scope related information.
Scope related information includes,
- for each scope, start line, end line, start column, end column
and
- scope heirarchy.
As scope is delimited by "{" and "}" (for an input

[LLVMdev] LowerDbgDeclare results in redeclaration of local variable
Hi Eric,
Thanks for patch information. I have checked the patch with my code and I see that it works.
But when I extract the variable and check the metadata information to retrieve the scope information,
I do not get exact scope, after optimization.
As you said that this is a work in progress, so can we expect full version on this in llvm3.3 release ?

Question on induction variable simplification pass
Hi Sanjoy,
I have attached the IR I got by compiling with -O2. This is just before we widen the IV.
To get the backedge taken count info I ran indvars on it and then replaced zext with sext.
I think regardless of where we decide to add this transformation in the pipeline, it should try to preserve as much information as it can. This means that we should generate sext for signed IVs and

valid BasicAA behavior?
My understanding is that alias analysis returns results in the function scope, not in loop scope.
Since both the phis access both global arrays, that should results in BasicAA conservatively returning MayAlias.
I debugged this a little bit and narrowed it down to the section of the code in BasicAAResult::aliasPHI() which has this comment-
// Analyse the PHIs' inputs under the assumption
