.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
.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 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 .
