Hi Roman, > That depends. > If there's LLVM intrinsic for it, then any normal optimization pass could do it. > In cttz's case it's mainly done in LoopIdiom pass. Oh yes. Thank you! Unfortunately several of the instructions of the bit manipulation extension don't seem to have an intrinsic already in LLVM. That will require to add some passes to the middle end. >

Hi list, We use samba 4.1.17 (debian's version) on several DCs. I just realized that one of them is desynced and cannot get it to resync. The long story: we got 5 DCs splitted over several sites. Recently we had to replace one of them (let's call him DC5). Since both had to run in parallel for data recovery/users work we decided to join a brand new DC (DC6) and latter demote the

I'd try to rejoin the faulty DC instead of copying sam.ldb files. I guess there are unique DC specific entries in the local database. Can be samba-tool replicate works if you try the push the settings from an other dc or pull em on the faulty dc. What command did you try andn on what dc?

Uh.. .. poweroff. ;-) And then cleanup the AD-DB and DNS old records. Dns tool and Domain user andn computer mananger shows all you need. This is because, not many records where shown in you ad-db.

Is there any intention of making floating absolute and negate primitive IR instructions? I ask because only a few days ago I was also faced with the task of implementing negate in my compiler, and finding no suitable IR instruction, simply subtracted from zero. But this is wrong. I could change my code to do the bit casting and fiddling, but I wonder: would that be lowered appropriately on all

...thought > about making that into a top-level goal. > What I said is sort of misleading in that the targets have a variety of "exotic" instructions that can effectively collapse multiple nodes in the critical path e.g. x86 BMI, PPC rlwinm, etc. Even stuff like whether the target has ANDN will affect the critical path (or an instruction taking a general truth table). Also the precise cost in a critical path of the individual instructions can vary a fair amount.to the extent that except for getting rid of mul's or div's it's not a universal win (even with mul, there are o...

Hi Nate! I don't see how that would work. Select doesn't work per element. Say we're trying to vectorize the following C++ code: if(v[0] < 0) v[0] += 1.0f; if(v[1] < 0) v[1] += 1.0f; if(v[2] < 0) v[2] += 1.0f; if(v[3] < 0) v[3] += 1.0f; With SSE assembly this would be as simple as: movaps xmm1, xmm0 // v in xmm0 cmpltps xmm1, zero // zero =

I want to replace an existing 32bit with a 64bit installation (Centos 5). There's an existing LVM with lots of partitions. Most are used for Xen guests. The system itself uses only one of them plus a separate /boot partition that is not on LVM. What's the best course of action here? Should I do the reinstall with kickstart or better manually and reuse the existing filesystem? As I

Hi, We would like to extend the vector operations in llvm a bit. We're hoping to get some feedback on the right way to go, or some starting points. I had previously had some discussion on this list about a subset of the changes we have in mind. All of these changes are intended to make target-independent IR (i.e. IR without machine specific intrinsics) generate better code or be

After a quick look at this thread, yes, i suggest you add a new DC. I also suggest you read : First this one. https://github.com/thctlo/samba4/blob/master/howtos/stretch-base-1.1-checkup.txt Now you are joining a existing domain. Line 20, the resolv.conf, set the first name server to you windows DC, the second to the internet. Besides that, before you install samba do these checks. Next is
