03ce187564 If running with "-K" really do not information about symbols from the a.out
argument.  Before this fix, after searching the currently-running kernel,
we would still search the a.out argument - completely override the in-kernel
list, essentially defeating the K flag's purpose.

97fa9b7739 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.

The style of this program is still atrocious (not fixed).

275ffbc6e6 Support runtime specification of the history counter type by whatever
generated the gmon data.  The support is currently limited to what is
easy to implement and/or needed:

    signedess: signed or insigned
    size: 8, 16, 32 or 64 bits
    format: a binary integer in gprof's format (gprof is not a cross-tool).

High-resolution kernel profiling uses signed 64-bit counters.  Normal
kernel profiling and user profiling use unsigned 16-bit counters but
should use 32-bit ones.

8109a9af1f Fixed some misspellings of 2 as sizeof(UNIT) so that they won't break
things when sizeof(UNIT) becomes a runtime parameter.  The relevant 2
is the one in profil(2)'s scaling of pc's to bucket numbers:

	   bucket = (pc - offset) / 2 * profil_scale / 65536

gprof(1) must duplicate this scaling, bug for bug compatibly, so it
must first do an integer division by 2 although this mainly makes
scales larger than 65536 useless.  sizeof(UNIT) was already wrong in
gprof4, but there were no problems because the fake profil scale is a
multiple of 2.

There are also some rounding bugs in the scaling, but these are only
problems if profil(2) is used directly to create unusual (and not
useful) scales.

8d57b8d3d2 Fixed printf format errors. In printgprof.c, also convert the scale
without possibly losing lots of precision, and print the scale using
%g instead of %d in case it is non-integral.  %g might not be the best
format for this.

4cd016e8fd Moved the definition of the machine-independent macro UNITS_TO_CODE
from <number of machines> machine-dependent headers to the one
non-header here it is used so that it is easier to fix.  This macro
just divides the machine-dependent offset OFFSET_OF_CODE by the
machine-independent scale factor sizeof(UNIT), as required for bug
for bug compatibility with the scaling of pc's in gprof.c.  UNIT is
the type of a profiling counter, and its size has nothing to do with
the correct scale factor except both are usually 2.

3fc980b135 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.

13a29a8a17 Enable gprof on alpha.
* alpha.{c,h} are same as i386.{c,h}.
* Force address calculation to be done in long precision(64bit on alpha)
  rather than double precision(52bit).

7e74cac42e 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.

5584f22bb3 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.

43ab5f3877 Don't ignore symbols containing "$". C++ destructors and other
special functions have names containing dollar signs, and ignoring
them causes gprof to produce incorrect and sometimes bizarre results.
The comment in the original code said that dollar signs were excluded
because they are used in Pascal labels.  That's not much of an
issue these days.

ff18d3781d 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.
