49c4458c80 Remove single-space hard sentence breaks. These degrade the quality
of the typeset output, tend to make diffs harder to read and provide
bad examples for new-comers to mdoc.

bd76338214 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).

6578739ddb 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.

70ccb43727 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.

664ece1203 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.

5b11e2a2f4 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.

993b274d03 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.

20aa44a88c 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.

467c7d29da 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.

f8b51172cd 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.

39cdb05128 Implemented non-statistical kernel profiling. This is based on
looking at a high resolution clock for each of the following events:
function call, function return, interrupt entry, interrupt exit,
and interesting branches.  The differences between the times of
these events are added at appropriate places in a ordinary histogram
(as if very fast statistical profiling sampled the pc at those
places) so that ordinary gprof can be used to analyze the times.

gmon.h:
Histogram counters need to be 4 bytes for microsecond resolutions.
They will need to be larger for the 586 clock.
The comments were vax-centric and wrong even on vaxes.  Does anyone
disagree?

gprof4.c:
The standard gprof should support counters of all integral sizes
and the size of the counter should be in the gmon header.  This
hack will do until then.  (Use gprof4 -u to examine the results
of non-statistical profiling.)

config/*:
Non-statistical profiling is configured with `config -pp'.
`config -p' still gives ordinary profiling.

kgmon/*:
Non-statistical profiling is enabled with `kgmon -B'.  `kgmon -b'
still enables ordinary profiling (and distables non-statistical
profiling) if non-statistical profiling is configured.

63eff9d9b8 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.
