Linux in a Nutshell, 6th Edition

Name

gprof

Synopsis

gprof [options] [object_file]

Display the profile data for an object file. The file’s symbol table is compared with the call graph profile file gmon.out (previously created by compiling with gcc -pg). Many of gprof’s options take a symbol-specification argument, or symspec, to limit the option to specified files or functions. The symspec may be a filename, a function, or a line number. It can also be given as filename:function or filename:linenumber to specify a function or line number in a specific file. gprof expects filenames to contain a period and functions to not contain a period.

Options

-a, --no-static

Do not display statically declared functions. Since their information might still be relevant, append it to the information about the functions loaded immediately before.

-b, --brief

Do not display information about each field in the profile.

-c, --static-call-graph

Consult the object file’s text area to attempt to determine the program’s static call graph. Display static-only parents and children with call counts of 0.

--demangle[=style], --no-demangle

Specify whether C++ symbols should be demangled or not. They are demangled by default. If profiling a program built by a different compiler, you may need to specify the mangling style.

--function-ordering

Print suggested function order based on profiling data.

--file-ordering file

Print suggested link line order for .o files based on profiling data. Read function name to object file mappings from file. This file can be ...
