.SH SYNOPSIS
|
|
.B bprint

.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 .
