l
ld(1) ld(1)
-V Output a message giving information about the version of ld being used.
-Z Allow run-time dereferencing of null pointers. See the discussions of -Z and pointers
in cc(1). (This is the complement of the -z option.)
-Pd Reorder debuggable functions. Ordinarily -P does not reorder functions from .o
files with debugging information, because reordering renders them non-debuggable.
This option overrides this and reorders the functions.
-PD filename Save link order file generated by fdp during linking with -P option into user-
specified file. This option is incompatible with the +ild option.
-PF filename Indicate to the linker to use the specified file for the linker file instead of generating it
using /usr/ccs/bin/fdp. This option is incompatible with the +ild option.
-dynamic This allows the linker to create a program which can use shared libraries. This is the
default for 64-bit links unless +compat is used. In 32-bit mode, the linker creates a
static executable if there are no shared libraries on the link line.
-noshared This option forces the linker to create a fully archive bound program.
+b path_list Specify a colon-separated list of directories (embedded path) to be searched at pro-
gram run-time to locate shared libraries needed by the executable output file that
were specified with either the -l or -l: option. An argument consisting of a single
colon (:) indicates that ld should build the list using all the directories specified by
the -L option and the LPATH environment variable (see the +s option).
+compat This option is ignored for 32-bit links. This option turns on compatibility mode in the
linker — 64-bit links mimic behavior of 32-bit links).
+copyobjdebug
Copy objdebug space.
+df file Used together with the -P option, this option specifies that file should be used as the
profile database file. The default value is
flow.data. See the discussion of the
FLOW_DATA environment variable for more information. This option is incompatible
with the +ild option.
+e symbol When building a shared library or program, mark the symbol for export to the
dynamic loader. Only symbols explicitly marked are exported. When building a
shared library, calls to symbols that are not exported are resolved internally.
+ee symbol This option is similar to the +e option in that it exports a symbol. However, unlike
the +e option, +ee does not alter the visibility of any other symbol in the file. In a
32-bit link or +compat mode 64-bit link, it has the effect of exporting the specified
symbol without hiding any of the symbols exported by default. In a 64 +std link, all
symbols are exported by default, so
+ee is not necessary to make a symbol visible.
However, it has the additional side effect of identifying the symbol as necessary, so
that it will not be removed when using dead code elimination (+Oprocelim ). Of
course, +ee still retains its export behavior if an option such as +hideallsymbols
is also given.
+fb Instructs the linker to run the fastbind tool on the executable it has produced. The
executable should be linked with shared libraries. For more details refer to fast-
bind(1), the
+help option, or the HP-UX Linker and Libraries User’s Guide manual.
This option is incompatible with the
+ild option.
+fbu Pass the -u option to the fastbind tool. For more details refer to fastbind(1), the
+help option, or the HP-UX Linker and Libraries User’s Guide manual. This option
is incompatible with the +ild option.
+gst Enable the global symbol table hash mechanism, used to look up values of symbol
import/export entries. The +gst and related options provide performance enhance-
ments through use of global symbol table which improves searching for exported sym-
bols. See dld.sl(5) and the HP-UX Linker and Libraries Online User Guide for more
information.
+gstsize size
Request a particular hash array size using the global symbol table hash mechanism.
The default value is 1103. The value can be overridden at runtime by setting the
HP-UX Release 11i: December 2000 − 5 − Section 1−−427
