Hi,
I am trying to use Callgrind to run determine the code coverage of a large
number of PDF files opened in Adobe Reader to then provide me with a much
smaller set of files that have unique code coverage.
The method is as follows:
1. I run Adobe Reader in Valgrind with the Callgrind tool enabled.
2. Then open the first file.
3. Now run Callgrind_Control (callgrind_control -w /tmp/ -s)
4. Note the number of "Basic Blocks"
5. Now close that file and open another
6. Repeat steps 3 to 5 for each file and only keep files that show new Basic
blocks have been hit
The issue I have is that this works fine if I use evince to read the files
but when I run Adobe Reader in the callgrind tool, callgrind_control does
not give me any output, just hangs with the "[requesting Status]" prompt:
/tmp$ callgrind_control -w /tmp/ -s
[requesting 'Status'...]
I suspect that this is because Adobe Reader is opening a number of processes
when run, but the main process callgrind.out file does not contain any
output, all output goes into the other process files.
/tmp$ ps -ef |grep Adobe

Is there a way around this issue?
Many thanks,
