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

The -D option has lower precedence than the -U option. If the same name is used in
both, the -U option and the -D option, the name is undefined regardless of the order
of the options on the command line.
Profiling Code Options
HP compilers provides the following options for profiling your code.
-G
-G
At compile time, the -G option produces code that counts the number of times each
arc in the call graph is traversed. At link-time, when you are building an executable
(but not a shared library) -G picks up profiled versions of certain system libraries and
picks up the gprof support library.
Example:
aCC -G file.C
The above example compiles file.C and creates the executable file a.out
instrumented for use with gprof.
See gprof(1) manpage for more information.
-p
-p
At compile time, the -p option produces code that counts the number of times each
routine is called. At link-time, when you are building an executable (but not a shared
library) -p picks up profiled versions of certain system libraries and picks up the prof
support library.
Example:
The following example compiles file.C and creates the executable file a.out
instrumented for use with prof.
aCC -p file.C
See the prof(1) manpage for more information.
+profilebucketsize
+profilebucketsize=[16|32]
This is a link-time option to support prof and gprof when building an executable,
but not a shared library. When prof or gprof startup code invokes sprofil, this
option specifies the size in bits of the counters used to record sampled values of the
program counter.
