-.TH BPRINT 1 "local \- 9/24/91"
-.SH NAME
-bprint \- expression profiler
-.SH SYNOPSIS
-.B bprint
-[
-.I option ...
-]
-[
-.I file ...
-]
-.SH DESCRIPTION
-.I bprint
-produces on the standard output a listing of the programs compiled by
-.I lcc
-with the
-.B \-b
-option.
-Executing an
-.B a.out
-so compiled appends profiling data to
-.BR prof.out .
-The first token of each expression in the listing is preceded
-by the number of times it was executed
-enclosed in angle brackets as determined from the data in
-.BR prof.out .
-.I bprint
-interprets the following options.
-.TP
-.B \-c
-Compress the
-.B prof.out
-file, which otherwise grows with every execution of
-.BR a.out .
-.TP
-.B \-b
-Print an annotated listing as described above.
-.TP
-.B \-n
-Include line numbers in the listing.
-.TP
-.B \-f
-Print only the number of invocations of each function.
-A second
-.B \-f
-summarizes call sites instead of callers.
-.TP
-.SM
-.BI \-I \*Sdir
-specifies additional directories in which to seek
-files given in
-.B prof.out
-that do not begin with `/'.
-.PP
-If any file names are given, only the requested data for those files are printed
-in the order presented.
-If no options are given,
-.B \-b
-is assumed.
-.SH FILES
-.PP
-.ta \w'/usr/lib/bbexit.oXX'u
-prof.out profiling data
-.br
-/usr/lib/bbexit.o creates
-.B prof.out
-when
-.B a.out
-exits
-.SH "SEE ALSO"
-.IR lcc (1),
-.IR prof (1)
-.SH BUGS
-Macros and comments can confuse
-.I bprint
-because it uses post-expansion source coordinates
-to annotate pre-expansion source files.
-If
-.I bprint
-sees that it's about to print a statement count
-.I inside
-a number or identifier, it moves the count to just
-.I before
-the token.
-.PP
-Can't cope with an ill-formed
-.BR prof.out .
