The record

Purpose: GNU gprof analyzes profiling data to show which parts of a program take the most execution time.
Outputs: It can print a flat profile and call graph, and provide annotated source output.
Build requirement: Programs must be compiled and linked with profiling enabled, typically using the compiler option -pg.
Data collection: The profiled program writes its data to gmon.out when it exits normally.
Combine profiles: gprof can sum statistics from multiple profile data files.
Sampling limits: Its time measurements do not account for time when a program is not running, such as time limited by I/O or swapping.
Instrumentation overhead: Profiling adds overhead to function calls, which the manual says can create artificial hot spots.
Line profiling: The -l line profiling feature works only with programs compiled by older GCC versions; newer GCC versions use gcov for line-by-line information.
Alternative in suite: The manual describes gprofng as a more modern profiler in Binutils that can read gmon files and provides more functionality.
Platforms: The Binutils project says its tools have been ported to most major Unix variants and Wintel systems.
Download: GNU Binutils releases are available from ftp.gnu.org and sourceware.org.
Support channels: The project lists Bugzilla for bug reports and mailing lists for bug reporting and discussion.
License: The gprof manual is distributed under the GNU Free Documentation License version 1.3.
