NAME

pxp − Pascal execution profiler

SYNOPSIS

pxp [ −acdefjLnstuw_ ] [ −23456789 ] [ −z [ name ... ] ] name.p

DESCRIPTION

pxp can be used to obtain execution profiles of Pascal programs or as a pretty-printer.  To produce an execution profile all that is necessary is to translate the program specifying the z option to pc, pi, or pix, execute the program, and then type the command

tutorial% pxp −z name.p

pxp generates a reformatted listing if none of the c, t, or z options are specified; thus

tutorial% pxp old.p > new.p

places a pretty-printed version of the program in old.p in the file new.p. 

OPTIONS

The use of the following options of pxp is discussed in the Pascal User’s Manual in the Sun Pascal Manual. 

−a Print the bodies of all procedures and functions in the profile; even those which were never executed. 

−c Extract profile data from the file core.

−d Include declaration parts in a profile. 

−e Eliminate include directives when reformatting a file; the include is replaced by the reformatted contents of the specified file. 

−f Fully parenthesize expressions. 

−j Left justify all procedures and functions. 

−L Map all identifiers and keywords to lower case. 

−n Eject a new page as each file is included; in profiles, print a blank line at the top of the page. 

−s Strip comments from the input text. 

−t Print a table summarizing procedure and function call counts. 

−u Card image mode; only the first 72 characters of input lines are used. 

−w Suppress warning diagnostics. 

−z [ name ... ] name.p
Generate an execution profile.  If no names are given the profile is of the entire program. If a list of names is given, then only the specified procedures or functions and the contents of the specified include files will appear in the profile. 

−_ Underline keywords. 

−d Use d spaces (where d is a digit, 2 ≤ d ≤ 9) as the basic indenting unit.  The default is 4.

DIAGNOSTICS

For a basic explanation do

tutorial% pxp

Error diagnostics include ‘No profile data in file’ with the c option if the z option was not enabled to pi; ‘Not a Pascal system core file’ if the core is not from a px execution; ‘Program and count data do not correspond’ if the program was changed after compilation, before profiling; or if the wrong program is specified. 

BUGS

Does not place multiple statements per line. 

Procedures and functions as parameters are printed without nested parameter lists, as in the obsolete Jensen and Wirth syntax.
