pxp — Pascal execution profiler

pxp [-acdefjnstuw_] [-23456789] [-z [name ...]] name.p

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 pi(1) or pix(1), to execute the program, and to then issue the command 
pxp -x name.p

A reformatted listing is output if none of the -c, -t, or -z options are specified; thus

pxp old.p > new.p

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

The use of the following options of pxp is discussed in sections 2.6, 5.4, 5.5 and 5.10 of the Berkeley Pascal User's Manual.

Print the bodies of all procedures and functions in the profile; even those which were never executed.
Extract profile data from the file core.
Include declaration parts in a profile.
Eliminate include directives when reformatting a file; the include is replaced by the reformatted contents of the specified file.
Fully parenthesize expressions.
Left justify all procedures and functions.
Eject a new page as each file is included; in profiles, print a blank line at the top of the page.
Strip comments from the input text.
Print a table summarizing procedure and function call counts.
Card image mode; only the first 72 characters of input lines are used.
Suppress warning diagnostics.
Generate an execution profile. If no name's are given the profile is of the entire program. If a list of names is given, then only any specified procedures or and the contents of any specified include files will appear in the profile.
Underline keywords.
With d a digit, 2 ≤ d ≤ 9, causes pxp to use d spaces as the basic indenting unit. The default is 4.

information on basic usage

pi(1), px(1)

Berkeley Pascal User's Manual.

For a basic explanation do

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.

Pxp appeared in 3.0BSD.

Does not place multiple statements per line.
