[Valgrind-users] Helgrind usage - query
I have cross-compiled Helgrind and using this tool to monitor a process. This process in turn spawns a few more processes. When I use the below command, ./valgrind --trace-children=yes -log-file=helgrind.log -tool=helgrind /bin/process1, I do not see the process 2 and process 3 when the command ps Is entered. Also, I do not observe logs from process 1. Can anyone help me if I have done anything incorrect here? This message is confidential and intended only for the addressee.

Try with --log-file=helgrind%p.log which puts the process ID in each file name, hence they will use different log files. J -- Everyone hates slow websites. So do we.

Re: [Valgrind-users] Helgrind usage - query
If I try to run the process standalone, I get the serial logs. But when the process is run from valgrind, none of the serial logs are output. Even printfs from the process are not being output. The same is the case when redirecting it to a file.

[Valgrind-users] floating point print error in ada
Hi, I'm using valgrind on a small Ada program (attached). The Ada program runs fine on the linux host, it prints 8.5. When I run the program through valgrind, it prints 0.0. Any ideas why this might be? I tried this with gnatmake with gnu 4.1.2 and gnu 4.2 on, $ uname -a Linux maple 2.6.32-22-generic-pae #36-Ubuntu SMP Thu Jun 3 23:14:23 UTC 2010 i686 GNU/Linux Thanks, Bob with System.Img_Real; use System.Img_Real; with System.Val_Real; use System.Val_Real; with Ada.Text_IO; procedure Sample is Buf : String (1 .. 3); Ptr : Natural := 0; begin Set_Image_Real (8.5, Buf, Ptr, Fore = 1, Aft = 1, Exp = 0); Ada.Text_IO.Put_Line (buf); end Sample; -- Everyone hates slow websites.

[Valgrind-users] Valgrind 3.8.1 DRD stuck
Hi, I was using Valgrind 3.8.1 DRD on Parsec 2.1 Benchmark suite. x264 program in Parsec runs for more than few hours and does not stop. I know it takes long time but the previous version 3.7.0 DRD finished the same program in 300 seconds. (I also tried to stop using Ctrl + c and Ctrl + z to suspend but that does not work to stop it either.) Do you have any idea? Environment: Intel Core 2 Duo CPU Ubuntu 12.04 gcc 4.6.3 The exact commnad line used including Valgrind DRD and program parameters: valgrind-3.8.1/bin/valgrind --tool=drd --first-race-only=yes --read-var-info=yes -v ./inst/i686-linux.gcc-pthreads/bin/x264 --quiet --qp 20 --partitions b8x8,i4x4 --ref 5 --direct auto --b-pyramid --weightb --mixed-refs --no-fast-pskip --me umh --subme 7 --analyse b8x8,i4x4 --threads 2 -o eledream.264 ./inputs/eledream_640x360_128.y4m Thanks. -- Everyone hates slow websites.
