--alloc_objects: Display allocated objects

--show_bytes: Display space in bytes

--drop_negative: Ignore negaive differences

Call-graph Options:

--nodecount=<n>: Show at most so many nodes [default=80]

--nodefraction=<f>: Hide nodes below <f>*total [default=.005]

--focus=<regexp>: Focus on nodes matching <regexp>

--ignore=<regexp>: Ignore nodes matching <regexp>

--scale=<n>: Set GV scaling [default=0]

EXAMPLES

google-pprof /bin/ls ls.prof

: Outputs one line per procedure

google-pprof --gv /bin/ls ls.prof

: Displays annotated call-graph via 'gv'

google-pprof --gv --focus=Mutex /bin/ls ls.prof

: Restricts to code paths including a .*Mutex.* entry

google-pprof --gv --focus=Mutex --ignore=string /bin/ls ls.prof

: Code paths including Mutex but not string

google-pprof --list=getdir /bin/ls ls.prof

: Dissassembly (with per-line annotations) for getdir()

google-pprof --disasm=getdir /bin/ls ls.prof

: Dissassembly (with per-PC annotations) for getdir()
