HP aC++/HP C A.06.25 Programmer's Guide

<qualifiers> are a comma-separated list of profile collection qualifiers.

Supported profile collection qualifiers:

arc Enables collection of arc counts.

dcache

Enables collection of data cache misses.

stride Enables collection of stride data.

loopiter

Enables collection of loop iteration counts..

all

Enables collection of all types of profile data. This is equivalent to

+Oprofile=collect:arc,dcache,stride,loopiter. This is the

default.

This option merely enables the application for collection of the various forms of profiling

data.

The environment variable PBO_DATA_TYPE controls the type of data collected at

runtime. It may be set to one of the following values, which must be consistent with

the +Oprofile=collect qualifiers used to create the application:

arc-stride Collects stride and/or arc counts. This is the default if

PBO_DATA_TYPE is not set.

dcache

Collects data cache miss metrics.

NOTE: Data cache miss metrics cannot be collected during the same run of an

application as stride and/or arc data.

Information Embedding Options

The +annotate option annotates the compiled binary with extra information.

-annotate=structs

The+annotate option annotates the compiled binary with accesses to C/C++ struct

fields for use by other external tools such as Caliper. By default, no annotations are

added.

Displaying Optimization Information

The +O[no]info option displays informational messages about the optimization

process.

+O[no]info

The +O[no]info option displays messages about the optimization process. This option

may be helpful in understanding what optimizations are occurring. You can use the

option at levels 0-4.
