Hello,
Do you know what's the order that the tools consume memory/sources?
I only know that memcheck is the most(12---18times).
Does "valgrind --tool=none date " mean running date command on coregrind
without other tools?
I use valgrind to test date command on arm ,
tools: none,lackey,callgrind,cachegrind is OK;
tools: memcheck,drd,massif,helgrind is not OK;
---they could run date command, but will display fault as below:

Thank you!
