Remove the advertising clause from UCB copyrighted files in usr.bin. This
is in accordance with the information provided at

Remove reference to unimplemented "-c" option.

Catch up with increasing the resolution suitable for high-res kernel
profiling from microseconds to nanoseconds in 1996. Picoseconds are
already needed.

Describe the choice of units for the per-call times in detail.

Expand *n't contractions.

Deal with double whitespace.

Fix after rev. 1.24 changes: bump document date, and remove -c
from SYNOPSIS.

Mechanically kill hard sentence breaks.

Retire support for gprof's -c option. All our currently supported
architectures only provide a dummy implementation.

mdoc(7) police: back out unproved changes in previous revision;
descriptions in the FILES section should be full sentences, as

Remove done() which was just exit() so use of warn()/err() can be made. Abort
on allocation failure instead of displaying a warning and deferencing NULL
pointer after. Spelling. Add prototypes. Add list of option in synopsis section
of man page, -d is not referenced because available as a compile option. It
should be made a runtime option btw.

Use `The .Nm utility'

mdoc(7) police: kill whitespace at EOL.

Add -K support to gprof(1), which enables dynamic symbol resolution from
the currently-running kernel (and supercedes an executable file argument
given). With this change, properly-compiled KLD modules are now
able to be profiled.

Remove whitespace at EOL.

mdoc(7) police: removed HISTORY info from the .Os call.

Grammar police: "its", not "it's", is the possessive form of "it".

Prepare for mdoc(7)NG.

mdoc(7) police: use the new features of the Nm macro.

Remove single-space hard sentence breaks. These degrade the quality

bad examples for new-comers to mdoc.

$Id$ -> $FreeBSD$

Add $Id$, to make it simpler for members of the translation teams to
track.

The $Id$ line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

.\" $Id$
.\"

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.

Construct the profile file name from the name of the executable. A program
compiled with -pg and run will generate a file <executable-filename>.gmon,
not gmon.out.

PR: bin/8426

Make profiling work for ELF. gprof now autodetects the format of
the executable file, so it will work for both a.out and ELF format
files. I have split the object format specific code into separate
source files. It's cleaner than it was before, but it's still
pretty crufty.

Don't cheat on your make world for this update. A lot of things
have to be rebuilt for it to work, including the compiler and all
of the profiled libraries.

Sort cross references.

Correct some man page cross references and file location references.

Xref clocks(7).

Another round of man page cleanups.

Down to only about 100 items left to cleanup! :-)

Added much-needed new options -[lL], to suppress printing of either the
call-graph or the flat profile, since often you only want one of them.

New flag -u to suppress functions whose name does not begin with an
underscore. Use it to avoid seeing badsw when profiling the kernel.

Print times more accurately (e.g. usec in %8.0f format instead of
msec in %8.2f format for averages) if hz >= 10000. This should have
no effect now since profhz is only 1024.
