[Kcachegrind-callgrind] can not get partial dumps of profile data

[Giovanni S. <gsa...@fu...>]

Hi

 I am using callgrind 0.9.11  (valgrind-2.2.0) to profile a C++ test
application that

comprises 4 steps, I would like to selectively collect profile data only =
when

the application runs the method:

=20

IncrementalTester::step4(void)

=20

The application is compiled with gcc 2.95.3.

I have tried the following:

=20

callgrind

-v

--log-file=3DreflTestIncrement

--num-callers=3D20

--simulate-cache=3Dno

--cacheuse=3Dno

--dump-before=3DIncrementalTester::step4

--dump-after=3DIncrementalTester::step4

incremental_tester.exe parameters.txt

=20

but I still get one single profile dump file callgrind.out.xxxxx, with =
the
whole run in it.

I also tried

=20

callgrind

-v

--log-file=3DreflTestIncrement

--num-callers=3D20

--simulate-cache=3Dno

--cacheuse=3Dno

--collect-atstart=3Dno

--toggle-collect=3D IncrementalTester::step4

incremental_tester.exe parameters.txt

=20

but still no success. Furthermore the option --dumpat=3D<funct> is not =
valid
for this version.

Any help to solve this is highly appreciated.
