I recently upgraded a codebase to use LLVM 3.9.0, up from 3.7.1. All seems to work well, except that I am unable to generate debug information. However, if I run objdump -g on the generated object file, it reports that the compile unit has no children: Contents of the .debug_abbrev section: Number TAG (0x0) 1 DW_TAG_compile_unit [no children] DW_AT_producer DW_FORM_strp

hello *, im running into two major bottlenecks an R script. 1. going through a 40mb file and reading in via readLines() 1 line at a time is almost an order of magnitude slow than the equivalent in python, im wondering if there are alternatives to readLines(), doing more lines at a time helps a bit 2. generating date sequences takes a long time, im basically doing something like

I restarted rsync, and this has been sitting there for almost a minute, barely moved several bytes in that time: 2014/11/545b06baa3d98/com.google.android.apps.inputmethod.zhuyin-2.1.0.79226761-armeabi-v7a-175-minAPI14.apk 6,389,760 45% 18.76kB/s 0:06:50 I straced each of the 3 processes rsync created and saw this (note: every time there were several seconds of no output, I

Hi I rsync from 4 machines to a single destination one, and I am certain the filenames they sync do not overlap. But from time to time rsync from a source machine gets stuck (not always the same source machine). I followed https://rsync.samba.org/issues.html and I gathered strace, lsof and netstat when the freeze occurred. I'd like to ask for any further debug info or ideas! General info

When in the process of testing out the 2.3.0 version of Dovecot, we noticed that on a busy server, imap-login can sometimes take 100% CPU and remain there indefinitely. We grabbed a gdb trace while it was happening: dovenull 36053 31.2 0.0 60460 17316 ?

Here's the details and some debugging I did for starters, but I have no idea where to proceed from here. Help please? Command to reproduce should be in the strace output below. -Dan P.S. Sorry for sending this a few times; I think only one will make it through to the list since I wasn't subscribed initially. $ rsync --version rsync version 3.1.0 protocol version 31 Copyright (C)

Hi again, I'd like to expand on the performance issues and plead for help. Here's one case which shows these odd hiccups: https://i.imgur.com/CXBPjTK.gifv. In this GIF where I switch back and forth between copy operations on 2 servers, I'm copying a 10GB dir full of .apk and image files. On server "hive" I'm copying straight from the main disk to an attached volume

Hi, I'm trying to squeeze performance out of gluster on 4 80GB RAM 20-CPU machines where Gluster runs on attached block storage (Linode) in (4 replicate bricks), and so far everything I tried results in sub-optimal performance. There are many files - mostly images, several million - and many operations take minutes, copying multiple files (even if they're small) suddenly freezes up for

thank john, i have used dump() , and each blocks had pred except entery block, i get the following output: fun main entry entry: %retval = alloca i32 %0 = alloca i32 %i = alloca i32 %j = alloca i32 %a = alloca [2 x i32] %n = alloca i32 %t = alloca i32 %"alloca point" = bitcast i32 0 to i32 %1 = getelementptr inbounds [2 x i32]* %a, i32 0, i32 0 %2 = load i32*

Now that we can gather diagnostic info, I think I know why our P2Vs kept failing last week. Another one just died right in front of my eyes. I think either the Ethernet or NFS server at this site occasionally "blips" offline when it gets busy and that messes up P2V migrations. The RHEV export domain is an NFS share offered by an old Storagetek NAS, connected over a 10/100 Ethernet.

Hi, All I want to implement DSWP Which is used for parallelization of loops. For this purpose, the loop was replaced with a new basic block in main function. And new functions were created and basic blocks of Loop assigned to them.I have checked blocks and branches for Succ and Pred relation and I have not found any problems. However I get the following error: * **opt:
