HP UX Fortran Software manual Options for controlling the Linker

Table 5 Options for controlling code generation (continued)

Option	Function
-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 -gon
	the command line, you must also specify it on the link line.
	nl
	For information about using this option to prepare programs
	for the debugger, see “Using the HP WDB debugger”
	(page 76).
+[no]gprof	Prepare [do not prepare] object files for profiling with
	gprof; see the gprof(1) manpage. 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.
	nl
	For information about using this option to profile programs
	with gprof, see “gprof” (page 89).
+k	Generate code for programs that reference a very large
	number of shared data items. The linker will issue a
	diagnostic message in the rare cases when this option is
	needed.
	NOTE: This option is valid only on the PA-RISC systems.
+pic={shortlongno}	Generate Position Independent Code (PIC) with short
	displacements (+pic=short) or long displacements
	(+pic=long) for use in shared libraries. The default is
	+pic=no.
	nl
	For information about using this option when creating
	shared libraries, see “Compiling with +pic” (page 59).
+[no]prof	Prepare [do not prepare] object files for profiling with
	prof; see the prof(1) manpage. The default is +noprof.
	If you compile and link separately and specify +prof on
	the command line, you must also specify it on the link line.
	nl
	For information about using this option to profile programs
	with prof, see “gprof” (page 89).
+[no]save	Save [do not save] all local variables in all subprograms.
	nl
	For information about using this option when porting, see
	“Uninitialized variables” (page 144).

Linker

The linker (ld) builds an executable program from the object files produced by the back end and the libraries. An important group of options for controlling the linker specify what libraries the linker should search and where it should search for them. Other options control the type of information that the linker should or should not include in its output file, such as symbol table information used by the debugger or marks identifying the output file as shareable or demand loadable. Table 1-6 lists and briefly describes options that control the linker.

NOTE: If you use the f90 command to compile and link on separate command lines and compile with any of the options (except -c) listed in Table 1-6, you must specify the same options on the link line as well.

Table 6 Options for controlling the Linker

Option	Function
-c	Suppress linking; produce object files only.
+[no]demand_load	Mark [do not mark] the output file from the linker demand
	load. If you compile and link separately and specify
