f7dd47a8d1 Build/install gprof on amd64 as well, after repocopying the MD bits.
Not that it has anything to process yet, but that comes next.

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.

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.

312a529b81 Added missing copyright. Obtain one and a vendor id from gprof.c. aout.c
was split off from gprof.c in rev.1.7 of the latter.  elf.c is mostly new,
but the old copyright sort of applies to it and is better than none.

Use __FBSDID() for the FreeBSD id.

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.

5e6220d9d0 * include/elf.h has been repo copied to include/elf-hints.h, and it no
longer includes machine/elf.h.
* consumers of elf.h now use the minimalist elf header possible.

This change is motivated by Binutils 2.11.0 and too much clashing over
our base elf headers and the Binutils elf headers.

3be5f1f5ce 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.

aac6614bdc Don't ignore weak symbols.
EGCS assign weak symbols to inline functions it couldn't inline (e.g. virtual
inline functions), template functions, etc. Omitting them result in quite bogus
profile.

Weak symbols created by __weak_reference are not really problem.

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.

ffbce11fea 32-bit counters aren't large enough for 100+MHz clocks. Use 64-bit
counters.  `4' in GPROF4 and gprof4 now means 8.  gprof4 needs to be
recompiled to match the kernel.

db6a4b8826 Use a (signed) int32_t counter instead of an `unsigned int' counter
for the GPROF4 case.  This allows a simpler method to be used for
non-statistical profiling (it allows overhead adjustments to be
subtracted from one counter without harm if that counter goes
negative; otherwise the adjustment would have to be distributed).

32 bit counters were already too small for GPROF4 with a 200MHz
clock.  int64_t counters should be used.

d4aa237228 Print times/call in ns if hz >= 10e7. hz will be this large for high
resolution profiling on Pentiums.  On a 100MHz Pentium, the resolution
is at best 10 ns and actually a few hundred ns, but units of 10's or
100's of ns would be inconvenient and the current units of 1 us are a
bit too coarse.
