[LLVMdev] MergeFunctions: reduce complexity to O(log(N))
Hi Stepan, Sorry for the delay. It's great that you are working on MergeFunctions as well and I agree, we should definitely try to combine our efforts to improve MergeFunctions. Just to give you some context, the pass (with the similar function merging patch) is already being used in a production setting. From my point of view, it would be better if we focus on improving its capability

[LLVMdev] MergeFunctions: reduce complexity to O(log(N))
Hello Sean and Tobias, Sean, Thank you. Could you describe Nick's ideas in few words or give me links to your discussion, so I could adapt my ideas to it. Tobias, Your patch fails on several modules in my benchmark (73 of ~1800 tests). I have sent one as attachment. See statistics files for more details, all the .ll files you could simply find in test-suite object directory (after

2.6.33 high cpu usage
With the ATI bug I was hitting earlier fixed, only my btrfs partition continues to show high cpu usage for some operations. Rsync, git pull, git checkout and svn up are typicall operations which trigger the high cpu usage. As an example, this perf report is from using git checkout to change to a new branch; the change needed to checkout 208 files out of about 1600 total files. du(1) reports

virtio-scsi <-> vhost multi lun/adapter performance results with 3.6-rc0
Hi folks, The following are initial virtio-scsi + target vhost benchmark results using multiple target LUNs per vhost and multiple virtio PCI adapters to scale the total number of virtio-scsi LUNs into a single KVM guest. The test setup is currently using 4x SCSI LUNs per vhost WWPN, with 8x virtio PCI adapters for a total of 32x 500MB ramdisk LUNs into a single guest, along with each backend

[LLVMdev] 2.1 Pre-Release Available (testers needed)
Hi, LLVM 2.1-pre1 test results: Linux (SUSE) on x86 (P4) Release mode, but with assertions enabled LLVM srcdir == objdir # of expected passes 2250 # of expected failures 5 I ran the llvm-test suite on my desktop while I was also working on that PC, so don't put too much trust in the timing info. Especially during the "spiff" test the machine was swapping

'object.size' takes a long time to return a value
I was using 'object.size' to see how much memory a list was taking up. After executing the command, I had thought that my computer had locked up. After further testing, I determined that it was taking 241 seconds for object.size to return a value. I did notice in the release notes that 'object.size' did take longer when the list contained character vectors. Is the time that it is

[LLVMdev] 2.6 pre-release2 ready for testing
LLVMers, 2.6 pre-release2 is ready to be tested by the community. http://llvm.org/prereleases/2.6/ If you have time, I'd appreciate anyone who can help test the release. To test llvm-gcc: 1) Compile llvm from source and untar the llvm-test in the projects directory (name it llvm-test or test-suite). Choose to use a pre- compiled llvm-gcc or re-compile it yourself. 2) Run make check,

Test Failure: <0.01> expected but was <0.01>
I have two database fields, and then I have a method which shows the difference. It''s simply def ev_diff ev_push - ev_fold end The value of ev_push is 0.26, value of ev_fold is 0.05, so the diff is obviously 0.01. I have an assertion written as: assert_equal 0.01, stats.ev_diff Which fails..but I have no clue why. The failure message follow: 1) Failure:

ggplot cumsum refined question (?)
OK, so maybe last night was a little too much at one throw, so I have reduced the data to two stations- one that has precipitation and one that does not. This is going to be in the context of a larger data set. I would like to be able to issue a ggplot command and have cum sum just act on the facets (factors) to apply this. library(chron) library(ggplot2) DF <- structure(list(date_time =
