Hi Tobias: Thanks for replying . So if I understand correctly, in LLVM currently, the Polyhedral model is being built ( LLVM IR -------> Poly Model ----------> LLVM IR ). This is for compile-time optimizations of loop-nests [e.g. loop-transformations to expose parallelism or improve locality etc]. Yes, thats great for optimizing loop-nests. As an additional, since the real value of LLVM

I don't see why not. I've used LLVM metadata to record type-inference information and to

Thanks Reid/Jonathon for your replies. Reid, An important case against module level flags is that it wont allow changing or resetting section names e.g. int a; #pragma clang section bss = "xyz" int b; In case above, users would like to see only 'b' placed in 'xyz' and not 'a' as well. Link pointed to by Jonathon seems to require same behavior.

Hi I read on LLVM blog that meta-data has been implemented to coney debug information to run-time system. Can one use meta-data to convey developer specifc hints to run-time system (e.g. JIT compiler)? Keen to know your thoughts on this.

Hi Reid, Unfortunately yes, it is. > If we do go with approach 3, I'd recommend adding a single metadata attachment that controls all sections a global could possibly live in (text, data, rdata, bss). I agree with this, although I think using metadata here wouldn't be right - don't we need to use attributes when dropping metadata would cause miscompiles? I was considering adding

Hi Javed, Developing a good loop vectorizer takes several years. The work on the GCC vectorizer began in 2004, and they spent several years improving and optimizing their vectorizer. They started by vectorizing simple loops, and added features that they needed in order to vectorize additional loops that were important for them. They started with a single-block loops, and later they added

It would be great to get "accurate" dependence analysis from polyhedral framework.

Hi all, Can anyone tell me the current state of instruction scheduling in LLVM, i.e. what all internal scheduling algorithms and whether constraint solving methods are used in LLVM for a single issue processor ? Please let me know if anyone has any information about it. Thanks, Siddharth -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi Nadav (and others who are related to this issue) - I saw some discussions on loop vectorizer that you are planning to write. Do you foresee using Polyhedral Framework (polly project) in some way in that. Thanks J. -------------- next part -------------- An HTML attachment was scrubbed...

I am looking for a large number (probably about 100 or so) low-cost phones that I can hang on the wall. I need the phones to use PoE. Do the Uniden phones support wall-mounting? These phones are not going to be high-usage; they simply need to be there in case of an emergency. Another question, along the same kind of lines, has anyone figured out how to keep the SoundPoint IP 600 receiver

According to digium's site, "Note: Please do not attempt to use the G.729 code in a SCSI-only system. We are currently working with VoiceAge to correct this issue." (found at http://www.digium.com/index.php?menu=asterisk_g729). Does anyone know what these issues are? Can anyone define SCSI-only system? I know this sounds kinda dumb, but I have a server with SCSI and IDE interfaces,

Javed, I'd like to add that, mostly through Tobi's efforts, we were able to have isl (the integer set library) on which Polly depends relicensed such that it is now distributed under the MIT license, and thus Polly should be eligible for inclusion as some of LLVM's core analysis and transformation passes. -Hal ----- Original Message ----- > From: "Javed Absar"

I am currently working on an Asterisk test system, and will be presenting a demo to the Board of Directors tomorrow night. I want to make sure I have all of my ducks in a row. The Asterisk system will be used to replace a Norstar MICS. The location has two PRI's coming in, with a few hundred DIDs. I know how to make * use the DIDs incoming, and I know how Nortel uses the DIDs. Now for the

Hi all, I need some help/guidance on writing the specs needed on a project that will be scaling up to 10,000 users. I will have some T1's to provide PSTN connectivity, and all the users will be SIP and/or H323 phones. Services offered will include conferences, voicemail (20 megs per users), etc Should I use SER in front of asterisk to handle the SIP load ? I think I should put the

Problem: Polycom SoundPoint IP phones (running SIP) ceases to send DTMF that Asterisk can detect and use. It worked in 1.0.5, but has not worked since. This has been verified on SoundPoint IP 300's and SoundPoint IP 600's. Workaround: It used to be that for DTMF to work, I had to set the mode in sip.conf to "inband". Without making any configuration changes on the
