NAME

hat-nonterm - finds and displays a non-termination path

SYNOPSIS

hat-nonterm [PROGNAME] [OPTION]...

DESCRIPTION

hat-nonterm is a one-shot tool for displaying a simple trace of a non-terminating program. The tool picks a function likely to be involved in the non-termination. It then displays a trace containing some number of reductions of this function.

Note that the traced program must first be compiled using the Hat tracing tools, and executed to generate a trace file.

OPTIONS

Possible options are as follows:
--showqual[=(t,f)]
               control whether to show functions qualified by the name
                of their module
--cutoff=DEPTH
               subexpressions in printed expressions are cut off and
                replaced with a placeholder below a depth of DEPTH
--numfn=NUM
               control how many instances of the suspicious function
                appear on the displayed extract of the non-termination
                path
--showrt[=(t,f)]
               control whether to show the root of the search path, or
                just the path from the suspicious function instance
--srcref[=(t,f)]
               control whether to show source references for each
                expression on the path
--showcount[=(t,f)]
               control whether to show the number of accesses to the
                file nodes
--shownode[=(t,f)]
               (DEBUGGING OPTION)
                control whether to show the octal addresses of the
                expression nodes, along side the pretty-printed versions
