filtercalltree reads a file containing a
call tree, as generated by the
sample(1) or
malloc_history(1) commands, and
filters or prunes it as specified by the options.
-invertCallTree- Print the call tree from hottest to coldest stack frame.
-pruneCount
count- Remove branches of the call tree that have count less than
count
-pruneMallocSize
size- Remove branches of the call tree that have malloc size less than
size, such as 500K or 1.2M.
-chargeSystemLibraries- Remove stack frames from all libraries in /System and /usr, while still
charging their cost to the caller.
-chargeLibrary
library-name- Remove stack frames from library-name, while still
charging their cost to the caller. This argument can be repeated for
multiple libraries.
-keepBoundaries- When charging libraries to callers, keep the top call into excluded
libraries.
