Re: [Valgrind-users] Making valgrind output diff-friendly

[Alan M. <ala...@jp...>]

I use grep when I invoke valgrind in my makefile (where the valgrind 
output from my entire regression suite is concatenated into 
/tmp/valgrind.report):

         grep -v STACK /tmp/valgrind.report | grep -v allocs | \
             grep -v 'memory error detector' | grep -iv copyright | \
             grep -v 'counts of detected' | grep -v 'HEAP SUMMARY' | \
             grep -v checked | sed 's/==[0-9]*== //' | \
             sed 's/(suppressed: [0-9]* from [0-9]*)//' >valgrind.report
