pxp
PXP(1) General Commands Manual PXP(1) NAME
pxp - Pascal execution profiler SYNOPSIS
pxp [ -acdefjnstuw_ ] [ -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 neces- sary is to translate the program specifying the z option to pi or pix, to execute the program, and to then issue the command pxp -z 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. -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. -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 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 any specified procedures or functions and the contents of any specified include files will appear in the profile. -_ Underline keywords. -d With d a digit, 2 <= d <= 9, causes pxp to use d spaces as the basic indenting unit. The default is 4. FILES
name.p input file name.i include file(s) pmon.out profile data core profile data source with -c /usr/share/pascal/how_pxpinformation on basic usage SEE ALSO
Berkeley Pascal User's Manual pi(1), px(1) DIAGNOSTICS
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.
