* gen-c-prog.awk: New awk script, lightly changed from

previously deleted make-c-prog.awk.  Converts a text file
	to a c function that prints that text.
	* flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m:  New files.
	Inputs to gen-c-prog.awk, containing text describing
	gprof output.
	* blurbs.c:  Removed.  Use *_bl.c instead.
	* Makefile.in: Use gen-cprog.awk to generate *_bl.c files
	from *_bl.m files.  Also, improve *clean rules.
	* printgprof.c (printgprof):  Usw new function names from *_bl.c.

call graph profile:
The sum of self and descendents is the major sort
for this listing.
function entries:
index the index of the function in the call graph
listing, as an aid to locating it (see below).
%time the percentage of the total time of the program
accounted for by this function and its
descendents.
self the number of seconds spent in this function
itself.
descendents
the number of seconds spent in the descendents of
this function on behalf of this function.
called the number of times this function is called (other
than recursive calls).
self the number of times this function calls itself
recursively.
name the name of the function, with an indication of
its membership in a cycle, if any.
index the index of the function in the call graph
listing, as an aid to locating it.
parent listings:
self* the number of seconds of this function's self time
which is due to calls from this parent.
descendents*
the number of seconds of this function's
descendent time which is due to calls from this
parent.
called** the number of times this function is called by
this parent. This is the numerator of the
fraction which divides up the function's time to
its parents.
total* the number of times this function was called by
all of its parents. This is the denominator of
the propagation fraction.
parents the name of this parent, with an indication of the
parent's membership in a cycle, if any.
index the index of this parent in the call graph
listing, as an aid in locating it.
children listings:
self* the number of seconds of this child's self time
which is due to being called by this function.
descendent*
the number of seconds of this child's descendent's
time which is due to being called by this
function.
called** the number of times this child is called by this
function. This is the numerator of the
propagation fraction for this child.
total* the number of times this child is called by all
functions. This is the denominator of the
propagation fraction.
children the name of this child, and an indication of its
membership in a cycle, if any.
index the index of this child in the call graph listing,
as an aid to locating it.
* these fields are omitted for parents (or
children) in the same cycle as the function. If
the function (or child) is a member of a cycle,
the propagated times and propagation denominator
represent the self time and descendent time of the
cycle as a whole.
** static-only parents and children are indicated
by a call count of 0.
cycle listings:
the cycle as a whole is listed with the same
fields as a function entry. Below it are listed
the members of the cycle, and their contributions
to the time and call counts of the cycle.

% the percentage of the total running time of the
time program used by this function.
cumulative a running sum of the number of seconds accounted
seconds for by this function and those listed above it.
self the number of seconds accounted for by this
seconds function alone. This is the major sort for this
listing.
calls the number of times this function was invoked, if
this function is profiled, else blank.

total the average number of milliseconds spent in this
ms/call function and its descendents per call, if this
function is profiled, else blank.
name the name of the function. This is the minor sort

in parenthesis it shows where it would appear in
the gprof listing if it were to be printed.

This table describes the call tree of the program, and was sorted by
the total amount of time spent in each function and its children.
Each entry in this table consists of several lines. The line with the
index number at the left hand margin lists the current function.
The lines above it list the functions that called this function,
and the lines below it list the functions this one called.
This line lists:
index A unique number given to each element of the table.
Index numbers are sorted numerically.
The index number is printed next to every function name so
it is easier to look up where the function in the table.
% time This is the percentage of the `total' time that was spent
in this function and its children. Note that due to
different viewpoints, functions excluded by options, etc,
these numbers will NOT add up to 100%.
self This is the total amount of time spent in this function.
children This is the total amount of time propagated into this
function by its children.
called This is the number of times the function was called.
If the function called itself recursively, the number
only includes non-recursive calls, and is followed by
a `+' and the number of recursive calls.
name The name of the current function. The index number is
printed after it. If the function is a member of a
cycle, the cycle number is printed between the
function's name and the index number.
For the function's parents, the fields have the following meanings:
self This is the amount of time that was propagated directly
from the function into this parent.
children This is the amount of time that was propagated from
the function's children into this parent.
called This is the number of times this parent called the
function `/' the total number of times the function
was called. Recursive calls to the function are not
included in the number after the `/'.
name This is the name of the parent. The parent's index
number is printed after it. If the parent is a
member of a cycle, the cycle number is printed between
the name and the index number.
If the parents of the function cannot be determined, the word
`<spontaneous>' is printed in the `name' field, and all the other
fields are blank.
For the function's children, the fields have the following meanings:
self This is the amount of time that was propagated directly
from the child into the function.
children This is the amount of time that was propagated from the
child's children to the function.
called This is the number of times the function called
this child `/' the total number of times the child
was called. Recursive calls by the child are not
listed in the number after the `/'.
name This is the name of the child. The child's index
number is printed after it. If the child is a
member of a cycle, the cycle number is printed
between the name and the index number.
If there are any cycles (circles) in the call graph, there is an
entry for the cycle-as-a-whole. This entry shows who called the
cycle (as parents) and the members of the cycle (as children.)
The `+' recursive calls entry shows the number of function calls that
were internal to the cycle, and the calls entry for each member shows,
for that member, how many times it was called from other members of
the cycle.
