+DSmodel Perform instruction scheduling appropriate for a specific implementation of
the PA-RISC architecture. model can be one of the following:
• PA-RISC version number (1.1 or 2.0)
• A model number (for example, 750 or 870).
• One of the PA-RISC processor names (for example, PA7000, PA7100,
or PA8000).
For information about using this option, see “Compiling for different
PA-RISC machines” on page 87.
On Itanium processor family architecture, the defined values for model are:
• blended: tune for best performance on a combination of processors (i.e.,
Itanium or Itanium 2 processor). This is the Itanium architecture
default.
• itanium: tune for best performance on an Itanium processor
• itanium2: tune for best performance on an Itanium 2 processor
• native: tune for best performance on the processor on which the compiler
is running.
-g Generate debugging information needed by the debugger. This option is
compatible with optimization levels 0, 1, and 2. If you compile and link
separately and specify -g on the command line, you must also specify it on
the link line.
For information about using this option to prepare programs for the debugger,
see “Using the HP WDB debugger” on page 118.
+[no]gprof Prepare [do not prepare] object files for profiling with gprof; see the
gprof(1) man page. The default is +nogprof. If you compile and link
separately and specify +gprof on the command line, you must also specify it
on the link line.
For information about using this option to profile programs with gprof, see
“gprof” on page 143.
