Hi, We are proposing a loop fusion pass that tries to proactive fuse loops across function call boundaries and arbitrary control flow. http://reviews.llvm.org/D7008 With this pass, we get 103 loop fusions in SPECCPU INT 2006 462.libquantum with rate performance improving close to 2.5X in x86 (results from AMD A10-6700). I took some liberties in patching up some of the code in

Hi everyone, I''ve tried posting the same question to the list last Friday but somehow did not see it being posted.. I''ve just started with Rails and Ruby. I just started to play one of those RPG and to get my feet wet I''m writing an app to keep track of item fusions. So the scoop is that item can be fused with another items to create a higher level item. The higher

Hi This is a question prompted by the mac version of R, but as I see it, it should have broader interest. These days the CRAN Mac binary per default compiles every package for two architectures. First i386 and then ppc. In between the two compilation runs, any object files in pkgname/src is removed. This cleanup is necessary since otherwise Make would not recompile the object files

Hi Qi, No, we don’t have loop fusion. The loop fusion transformation itself is easy, but the profitability and legality checks are challenging. For legality, you would need to analyze the memory that you access and figure out that it is legal to fuse the loops. For profitability you would need to predict the effect on performance. You would need to predict register pressure and resource

After upgrading my VMware Fusion (10.1.3) Arch Guest to the latest with OpenSSH upgraded from 7.7p1 to 7.8p1, found that ssh from macOS Sierra (10.12.6) host to Arch guest via local NAT port forwarding failed, but via Arch LAN IP worked, downgraded OpenSSH from 7.8p1 to 7.7p1 fixed the problem. Any idea about this bug? VMware Fusion NAT Port Forwarding setup: VMware Fusion ? NAT Port Forwarding

I recently started using compiz-fusion. After spending months looking at an anemic little rectangular on-screen volume control when I use the volume buttons on my ubuntu thinkpad T60p, all of a sudden I noticed that I was getting a nice, big, robust rounded-corner display (somewhat mac-like). Now it's gone again. I really have no clue whether this came from compiz-fusion, emerald, a plugin,

Howdy. I have a application I'm developing where I need to encrypt the data inside an OGG stream. I will be using a regular block cypher (AES, or others... configurable); and I would like to encrypt the pages in an OGG stream. I'm thinking that if I sit my decrypter in between the reading application and the encrypted file, you should be able to use all the normal seeking

Hi all, I have created a patch (up for review at: http://reviews.llvm.org/D17386) that does Loop Fusion implementation. Approach: Legality: Currently it can fuse two adjacent loops whose iteration spaces are same and are at same depth. Dependence legality: Currently, dependence legality cannot be checked across loops. Hence the loops are cloned along a versioned path, unconditionally fused

Hi, I am a student and my team is trying to identify a suitable topic for our compiler class final project. The requirement is to implement some optimization in LLVM that is not already existed, at least not in the list of standard opt that LLVM already has. We are looking at loop fusion as a potential candidate topic. Since we are all new to LLVM we would like to ask for experts' opinions

Check behaviour of Compiz Fusion KDE 0.6.2-3.1 Hello, I am trying out the release "Compiz Fusion KDE 0.6.2-3.1" on my openSUSE system. I would like to share some more experiences about its usability. 1. Context menu by title bar 1.1 The context/actions menu that appears after a right click on the window title is displayed in English despite German is my primary language in the

Hi, I would like to add an ISD node for an fmad operation (named either FMAD or FMULADD). It will have the semantics of returning the same result as the separate multiply and add with the intermediate rounding step, and not a differently rounded result. The motivation is to share code with the various FMA forming DAG combines, but will be generally more useful on targets that support it

If you're interested to work on it then it'd be great! Hi Devang, Do you know if any pass is taking metadata to avoid un-optimizing? Loop fusion can make it worse if you have strong

hi there, a number of users of ubuntu gutsy with nvidia cards are experiencing a serious memory leak under compiz. This leak essentially renders compiz unusable for us. Gutsy ships with a compiz versioned at 0.6.0 +git20071008 , which I imagine isn't that different from the current compiz, and with the current 100.14.19 nvidia driver running under a 2.6.22 kernel. I'm just wondering

Listmates, I am narrowing down the reason that compiz will not autostart on my Toshiba P35 laptop running openSuSE 10.3. There seems to be a mutual exclusion between being able to do manual start with "compiz --replace ccp &" and having compiz start at all with "libIndirectGL.so.1" present in /usr/lib. To get compiz to start on my system, I must manually rename the

The R function hclust is used to do cluster analysis, but based on R help I see no way to print the actual fusion distances (that is, the vertical distances for each connected branch pairs seen in the cluster dendrogram). Any ideas? I'd like to use them test for significant differences from the mean fusion distance (i.e. The Best Cut Test). To perform a cluster analysis I'm using: x
