HP UX Caliper Software Fprof Measurement Report Description, Unknown Source Files, Directory

Table 24 Information in fcover Measurement Reports

Column	Description
Reached	Number of functions in the given source file that executed at least once.
Unreached	Number of functions in the given source file that did not execute.
%Unreached	Percentage of functions in the given source file that were never executed.
Load Module	Load module name in Load Module Summary.
Source Directory	Source directory path in Source Directory Summary.
Source File	Source-file path in Source File Summary.

See Table 25 (page 200).

Table 25 Information in Per-Source-File fcover Measurement Reports

Column	Description
Reached	“Yes” or “No” indication of whether the named function was ever executed.
Function	Name of the function. The load module, main executable or shared library, containing
	the function precedes the function name and is separated from it by “::”.
Source File [Line]	Base source file name, without path information, and starting line number of the named
	function. The tilde (“~”) precedes line numbers when they are approximate due to
	optimization.

Unknown Source Files

If the source file information for a function has been stripped, which is often done with system libraries, then HP Caliper reports on those functions separately. The report shows an additional line in the Source Directory Summary and Source File Summary tables for Unknown Source Files and the Totals coverage statistic includes them.

At the end of the per-source-file function coverage tables is an optional table for Unknown Source Files. To generate this table, use unknown in addition to the other -roption settings.

-r for Function Coverage Reports

-r [module][:directory][:file][:function][:unknown][none][all]

Default value is module:directory:file:function:unknown.

module	Shows data by load module.
directory	Groups data by source directory.
file	Generates Summary Report by source file.
function	Shows function level detail by source file.
unknown	When used together with the other report options, provides additional information
	about functions from unknown source files in the summary and detail coverage
	reports.

fprof Measurement Report Description

With the fprof measurement, produced by the fprof measurement configuration file, HP Caliper measures and reports sampled instruction pointers (IPs). The fprof measurement samples the instruction pointer (IP) at a regular interval (that is, at a particular number of CPU cycles). This provides a statistical identification of where CPU events are occurring.
