--base=<base>
Subtract <base> from <profile> before display
Reporting Granularity:
--addresses
Report at address level
--lines
Report at source line level
--functions
Report at function level [default]
--files
Report at source file level
Output type:
--text Generate text report [default]
--gv Generate Postscript and display
--list=<regexp>
Generate source listing of matching routines
--disasm=<regexp>
Generate disassembly of matching routines
--dot Generate DOT file to stdout

Call-graph Options:
--nodecount=<n>
Show at most so many nodes [default=80]
--nodefraction=<f>
Hide nodes below <f>*total [default=.005]
--edgefraction=<f>
Hide edges below <f>*total [default=.001]
--focus=<regexp>
Focus on nodes matching <regexp>
--ignore=<regexp>
Ignore nodes matching <regexp>
--scale=<n>
Set GV scaling [default=0]
EXAMPLES
pprof /bin/ls ls.prof
Outputs one line per procedure
pprof --gv /bin/ls ls.prof
Displays annotated call-graph via 'gv'
pprof --gv --focus=Mutex /bin/ls ls.prof
Restricts to code paths including a .*Mutex.* entry
pprof --gv --focus=Mutex --ignore=string /bin/ls ls.prof
Code paths including Mutex but not string
pprof --list=getdir /bin/ls ls.prof
Dissassembly (with per-line annotations) for getdir()
