I don't know how good it is, but the applications seem obvious. e.g. compiling programs in any of a number of original formats to run natively on CPUs that have a working simple C compiler (maybe only K&R or C89) but don't have an LLVM back end. The source program could be in modern C, C++, or any other high level language or assembly language with a translator to LLVM. On Tue, Aug

Hi All, 2 of my summer interns (Aimee Dipietro and Greg Simpson) used their time over the summer to resurrect the LLVM C Backend: https://github.com/draperlaboratory/llvm-cbe Improvements include recovery of simple for/while loops (instead of goto), better variable naming, inline asm support, and making it work on a more recent version of llvm. I believe they used the repository here as a

I strongly disagree. If you think this is the case, we should probably start a new thread (rather than ressurecting this one) with the context of what you want to do and why you think it should be on a

The reason why I say it should be done in a separate branch is that the final design is not necessarily the same as the first initial implementation. There are things that will break and this kind of change touches almost everything, not just the core LLVM libraries. It is hard to get right the first time, and developing it in a sandbox will dramatically decrease the amount of churn that will show

I have a question about Ogg. (which, ironically, means i'm posting to the wrong list. I don't know of an Ogg list though, and if i'm posting to the wrong list, please inform and forgive me) A while back I read how some of the developers had added MIDI support to the Ogg stream format. While just in early stages, this reminded me of a thought that had been passing through my

Outside of what was listed below, which you would have to go back into the other emails/reviews to get into more details, I believe the handling of global constants expressions was problematic with the API's that I had implemented. That said, changes of this magnitude should be done in a branch instead of mainline trunk. Micah -----Original Message----- From: llvmdev-bounces at cs.uiuc.edu

Hi, I was working on alias analysis using LLVM-2.6 previously. But I just downloaded LLVM-2.7 and found AndersenAA is not there. What happened for andersen's IPA alias analysis? Has it been deleted for some reason? Thanks. Lei -------------- next part -------------- An HTML attachment was scrubbed... URL:

I have had a problem with mkdiskimage for quite a while. It seems to always exit with the syntax messages. I'm not really familiar enough with Perl to figure out exactly what it's checking for there that it determines is incorrect, but, my guess would have to be that it doesn't like the letter. Eg, I think the last time it suceeded I was running it on sda, but, not I'm typically

Hello all, There is a new Windows package of NUT. It now contains nut-scanner binary. Note that there is a known issue with libupsclient.dll with nut-scanner. The scan of NUT servers using nut-scanner will not work for now. You can find it at : http://www.networkupstools.org/source/2.6/NUT-Installer-2.6.3-1.msi Please send feedback to the list.

OpenSSH Developers, I'm researching whether or not OpenSSH is a viable commercial alternative to F-SECURE SSH or SSH.COM's ssh, but I'm not getting the kind of results that I expected from a "Non patent encumbered ssh client". When I attempt to build OpenSSH against an OpenSSL build without rc5, idea, or rsa it bombs since OpenSSL doesn't place the header files in the

This patch implements persistent grants for the xen-blk{front,back} mechanism. The effect of this change is to reduce the number of unmap operations performed, since they cause a (costly) TLB shootdown. This allows the I/O performance to scale better when a large number of VMs are performing I/O. Previously, the blkfront driver was supplied a bvec[] from the request queue. This was granted to
