Question about versioning of LVVM IR
Hello, It is likely that I missing something however I have to ask. We are working on Mull project https://github.com/mull-project which deals with LLVM IR in the first place so it is often that we encounter errors like the following one when we do things like parseAssemblyString(IR, Err, GlobalCtx);`: ``` test: <string>:7237:187: error: invalid field 'variable' !1526 = di...

JIT client - late cross references
Hello Alex, This is an interesting approach! Thank you for that! I understand the basic idea but sadly... My skills in handling the IR are not very high, so I can't imagine where and when to replace the calls to b() with the trampoline. The only thing I can handle would be creating that trampoline variable. Also will this approach be a problem for really time critical tasks? Since I replace

LLVM-based Mutation Testing, first results.
...ciently. Also, it is a bit more complicated, since we do not know the domain of LLVM internals very well. Here I leave links to the results in case you are interested. https://lowlevelbits.org/ADTTests/ https://lowlevelbits.org/IRTests/ Source code of the tool itself is here: https://github.com/mull-project/mull We hope it helps to improve the quality of LLVM even further. Thanks for reading. We appreciate any feedback. Best regards, Alex. -- AlexDenisov Software Engineer, http://lowlevelbits.org

Remote system up/down monitoring tool?
...ails, it emails me to say the other box might be down. It then emails me again the next time the other box appears to be up. Of course, this can't distinguish between the remote box really being down and there being a network problem somewhere between the local and remote boxes. I've been mulling over the idea of a more sophisticated scheme, where a number of boxes send each other messages, indicating not only their presence, but which other boxes they believe to be up. Then if a box goes down, the other boxes all see it has gone and agree that it really is down. However, if there is ins...

Antispam with Postfix
I am mulling over the thought of replacing my current solution, it works very well except for the following two issues: 1. LDAP recip verification for only one server, this gateway services multiple domains who's directories are independent. I need to be able to verify the various domains off of indepen...

Roaming Profiles
I'm mulling over the idea of replacing my Win 2k MS AD using Samba. But I'd like to retain roaming profile capability for all my users. Based on your experience is it stable enough to implement for a production environment? I have only 30 using Win 2k Pro and some XP. What are the pit falls I need to l...

Antw: Re: openssh kills the stty values?
Hi, thanks for your answer. I can reproduce your error in my HP-UX system and solved it ;-)). I built socalled software-depots for distributing the openssh-package and put the start command in the postinstall-script. The shell of this postinstall script has the bahavior that intr ^C won't work properly. So I did your trick with "/sbin/init.d/sshd stop/start" from a shell where ^C

LLVMContext: Threads and Ownership.
Hi All, ORC's new concurrent compilation model generates some interesting lifetime and thread safety questions around LLVMContext: We need multiple LLVMContexts (one per module in the simplest case, but at least one per thread), and the lifetime of each context depends on the execution path of the JIT'd code. We would like to deallocate contexts once all modules associated with them have

Oen source IP phone, maybe?
Its another one of my "If I only had time...damn this sleep thing" ideas, but I really wonder how hard/cost effective it would be to build an open source IP phone or phone adapter (ala ATA). In about 20 minutes of mulling and research, I figure you could do it for about $40 in parts plus coding time... 1 DS80C400 Ethernet enabled microcontroller with built in IPV4/V6 stack $10 1 DSP56K hardware DSP (you may even be able to dispense with this if the C400 is fast enough to do the codecing...then you just need a...

Highpoint Rocketraid 2240
Has anyone on the list used one of these w/Linux? We currently use Linux + Cinelerra for editing uncompressed video (and a few dual G5 macs running Final Cut Pro). Current editing stations are getting a bit long in the tooth so I've been mulling over a mass upgrade. 8-) These cards are interesting to me because they are PCI-X and support 4 SATAII drives per multilane/infiniband connector for a total of 16 drives. Multilane is interesting to me because the editor can use a SFF system (tiny desktop footprint) with 1M multilane cable...

CYGWIN Rsync exclude/include problem
I'm having troubles with getting rsync 2.5.5 (CYGWIN version) to include/exclude files they way I expect it to. I have mulled over the list postings and man pages regarding this and I am either missing something or ... well I don' know. I have a drive with 12 folders in the root however, I only want to rsync 5 of them (the ones marked with an *) and in those 4 I want to exclude certain folders and file patterns. Th...

If yes then this doesnt look all that bad or invasive at first sight (if the put_user() workaround can be expressed in a cleaner way), but in any case it would be...
